DJ Mixer

A DJ mixer is a piece of hardware used by disc jockeys (DJs) to combine audio sources and sound effects during live performances. Beyond allowing the DJ to create his or her own audio through other sources, a DJ mixer makes it easier for a DJ to continuously play music without any downtime, so people keep dancing without interruption or a single moment of silence. In many ways, a DJ mixer unit is similar to other audio mixers, but there are differences in the DJ’s equipment that make a DJ mixer special. Most mixers can record audio, allowing the DJ to make an original mix that can be played on cue.

The DJ mixer is almost like any other audio mixer. It takes one or more audio sources and applies changes by altering the basic components of the audio’s sound. One of the defining features of a mixer is the crossfader, which acts as two faders colliding with each other. This allows the DJ to quickly transition from one song to the next, fading out one audio source and simultaneously fading in another source. Another defining feature is the ability to feed a non-playing audio source into headphones.


Aside from crossfading, DJ mixers have many other features that allow a DJ to create his or her own mix. There are often a variety of knobs and controls that permit the DJ to change the bass, treble and beat of the audio, along with other basic audio components. Sound effects are normally an afterthought with these units, so the DJ focuses more on mixing pre-existing music rather than adding sound effects, but most units have a few effects that can be used. These effects are typically generic and may be included on many different mixer models.

One obvious benefit from using a DJ mixer is that the DJ is able to keep music playing continuously without any downtime. This is done via the crossfader, because it generally allows the audio to decrease in volume for less than a second before picking back up. By using this technique, the DJ can keep people dancing and entertained all night, without there being any party-stopping silence between songs.

Another benefit of using a DJ mixer model is that the DJ can create his or her own DJ mixes. While some DJs prefer impromptu performances, others prefer to plan the event and have a list of songs and effects ready. DJ mixers can typically record a mix, so the DJ can have the lineup ready before the event occurs, and he or she can fine-tune the sound for his or her preference.

How Do I Become a Disc Jockey?

To become a disc jockey, it is usually necessary to go to college to acquire technical skills and training, whether the plan is to work in radio or club environments. It is also possible to acquire the necessary skills through apprenticeship and on the job training, although this can take longer. It also helps to be familiar with a wide variety of musical genres and to be able to keep pace with developments in the music industry through professional publications, events, and studious listening.

Radio disc jockeys need to be able to operate the equipment in the radio studio and also need some announcing skills. Many may give weather forecasts and other announcements during the show, and require training in broadcast journalism. In training, students learn how to use equipment and will also receive voice training so they acquire the vocal skills they need on the radio. Training to become a disc jockey often provides access to internships to allow students to get job experience.

A student who wants to become a disc jockey on a radio station may want to think about the kind of music that most interests her. She should develop broad familiarity with the genre she wants to work in. With a college education and some experience through internships, she can apply for positions at radio stations. Competition is often fierce, and it can help to have an outstanding application with credits like internships at major radio stations.

In the club environment, disc jockeys may not need broadcast journalism training, but it can help to have some education in music and audio engineering. Many colleges and universities offer this type of training. Disc jockeys can learn to operate sound equipment and may develop skills like mixing and playlist creation. Careers in clubs are less likely to require higher education, but applicants who choose not to go to college to become a disc jockey do need to acquire on-the-job training through internships under the tutelage of experienced disc jockeys.

It can take several years to become a disc jockey and even longer to build up a reputation in the field. Radio announcers may move between stations to take advantage of better job offers and more work opportunities, while club disc jockeys tend to develop freelance careers as they build up a list of clients and a following. Both can potentially become celebrities if they have charisma and a talent for adapting quickly to emerging trends in music; a disc jockey can attract a customer following that will put him in high demand and may allow him to negotiate better pay for his services.

4-Channel Mixer

Components used to combine audio sources are called mixers because they mix multiple audio sources into a combined output. An audio mixer can include dozens of inputs, with advanced features to provide sophisticated signal routing to a variety of destinations. A smaller 4-channel mixer typically has only four channels to handle incoming audio sources, but can have multiple audio output channels. Generally, a 4-channel mixer is designed to solve more basic audio problems.

Disc Jockeys (DJs) typically use a 4-channel mixer to combine two stereo audio sources so music can be cross-faded from one song to another. Mobile audio production crews for film or television may use a 4-channel mixer to combine audio from two actors while also capturing the ambient sound from the location. The mixers are frequently used in conjunction with a public address (PA) system where solo performers need to blend a vocal microphone with an instrument. A 4-channel mixer might also be used in an auditorium where a group of speakers each require their own microphone.

Most 4-channel mixers include design features for specific applications. A mixer used by DJs typically will feature slider controls that are well suited for smooth transitions between sources. Mobile audio production units might use rotary knobs so an accidental bump will not cause an unwanted adjustment of the volume level. Depending on the application, mixers may also provide light-emitting diode (LED) displays that warn when input levels are too high, or a larger multi-color LED display that shows output levels.

Regardless of the number of inputs provided, mixers often include additional features to further control the audio signal. These features might include equalization for each channel. Equalization allows the user to adjust different parts of the audio spectrum. Reducing low, or bass, frequencies can help reduce feedback problems. Reducing high, or treble, frequencies reduces hiss or noise created by the input source.

Some mixers include the ability to send a separate audio level to additional outputs. A musician may need to hear themselves through a stage monitor, as well as send a separate audio level to the PA system. Mixers can allow performers to adjust both the stage monitors and the sound heard by the audience by having separate controls for each output. The cost of the mixer typically will increase with the number of added features.

A well-designed audio mixer generally will operate without adding additional noise or distortion from its internal electronic circuits. Mobile mixers used by musicians or mobile applications are designed to endure the bumps and scrapes that happen with frequent movement. As needs grow, 4-channel mixers can be replaced by models that feature more inputs for additional audio sources.

Radio Disc Jockey

A radio disc jockey, also known as a DJ, is a person who works at a radio station. He or she is responsible for playing music and broadcasting news on the radio. The radio disc jockey may also read commercials on air and accept calls from listeners. Whether presenting a traffic or weather report, chatting with listeners by phone, or interviewing celebrities, a radio disc jockey must do so in a relaxed, professional manner.

Disc jockeys sometimes gain their training in radio broadcasting by earning a degree in broadcast journalism. They then find an internship at a radio station, receiving hands-on training in the field. Other aspiring DJs may work at school radio stations before becoming a professional disc jockey. No matter which path a future DJ takes, radio broadcasting is a competitive field that proves difficult to enter.

People with clear speaking voices and the ability to learn complex equipment have the best chance of finding work as a radio disc jockey. Disc jockeys usually specialize in specific genres of music, so they must be familiar with different music styles. They must also be able to speak in a knowledgeable manner about their chosen genres.


During a typical work schedule, DJs must manage their time well. This involves knowing the amount of time available so that music, commercials, news, interviews, and chatting fit into a set schedule. They must also have the ability to operate complex equipment that controls music and sound. DJs who play club music must be skilled at mixing music and beats as well.

Since radio stations play music 24 hours a day, a disc jockey may be required to work unorthodox hours. Many work late nights and weekends. More established DJs with a loyal following may work more desirable time slots. It's important that the new DJ develops a pleasing on-air personality so that listeners continue to listen to his or her radio program.

Disc jockeys do more than just present prerecorded music on the radio. They also may be responsible for writing commercials and skits. After writing the scripts, they perform the material. Disc jockeys are often required to do promotional work, making public appearances at community events and visiting schools.

Since the disc jockey is usually responsible for playing new music on the air, music companies often send the new albums of their recording artists for the DJ's review. This provides the DJ with opportunities to hear the latest music. As a result, disc jockeys stay abreast of trends and sometimes have the chance to influence the tastes of the listening public.

What Are Different Types of Disc Jockey Jobs?

Disc jockey jobs include those that are performed at a radio station, club or special event. In some cases, a disc jockey may do more than one of these types of jobs, either making special appearances for a radio station as a promotion, or to earn money on the side. No matter what career path is chosen, many disc jockey jobs are very similar. Even those inside a radio station often require a great deal of public interaction.

It is for this reason that most disc jockey jobs are not merely jobs that require selecting songs and running a broadcast, though these may be very important aspects of the disc jockey job description. Rather, a disc jockey must be a person that relates well to people. In the studio, the disc jockey is often one of the first contacts the general public has, answering a studio line to take requests, running contests and other interactive experiences. Disc jockeys that enjoy this type of work will find there are plenty of opportunities, as the most popular ones will have a great deal of public interaction.
Radio disc jockey jobs involve doing show preparation, running the broadcast, and dealing with listeners. In some cases, a disc jockey will be responsible for securing interviews with local personalities, or personalities within the music genre. In other cases, the format may simply call for playing music, updating sports, news and weather, and handling other general duties. While a disc jockey shift may last eight or more hours, they are seldom on the air that long.

Other disc jockey jobs are based at night clubs. These are usually part-time positions. The person performing the duties of a disc jockey in this setting is therefore likely to be a student, or will have another full-time or part-time job. Further, a live disc jockey may be required every night of the week at busier clubs, or only on weekends, depending on the crowd levels and expectations. This type of job can provide a good, steady part-time income for those interested in the work.

For those who want to start their own business, becoming a disc jockey is one way to do it. Privately-contracted disc jockeys are often in demand for weddings and other special events. Due to the fact many of these events happen on weekends, it is very easy for an individual to also have a full-time job. Doing this type of job on the side will require investment in equipment, lighting and sound systems. This could get to be very expensive.

How Do I Become a Mobile Disc Jockey?

A person looking to become a mobile disc jockey will need to have a love for music and the ability to operate DJ equipment proficiently. It is possible to get a start in the industry by visiting local disc jockey companies and seeking employment or by starting a mobile disc jockey entertainment company. An aspiring mobile disc jockey needs to have a broad knowledge of various music genres, and a desire to entertain a crowd. Although there are several training programs available, there is no specific training that is required in order to become a mobile disc jockey.

The duties of a mobile disk jockey include traveling to a variety of venues with the expectation of being able to play any genre of music required by the client. A fun and outgoing personality is also needed in order to become a mobile disc jockey, as the job demands that the DJ keep the crowd excited and engaged throughout the session. The skills needed to please a crowd and keep guests engaged in the music can either be self-taught or learned through watching and listening to other disc jockeys.

It is important to keep in mind that although being a disc jockey might appear to be all fun-and-games, it is serious work. An aspiring mobile disc jockey will need to work tirelessly at promoting his services in order to find clients and gigs. This is quite challenging in comparison to the typical disc jockey job where one has a regular show at a local radio station or nightclub. A marketing plan will also be needed in order to determine the best method for attracting clients, whether for weddings, parties, or any other event that requires mobile disc jockey services.

In order to become a mobile disc jockey, it is necessary to develop good contract terms to present to potential clients. New DJs will need to outline their services and payment policies in order to focus their attention on their specialties and ideal clients. Having structured pricing guidelines will also help to attract serious customers and quickly filter out unqualified leads.

Finally, in order to become a successful mobile disc jockey, time management skills are critical. Good mobile DJs always work with a business calendar in order to manage their schedules. Fridays and weekends are usually the busiest times on the schedule and many even find themselves booked months in advance. Aspiring mobile disc jockeys must learn how to maintain a business calendar and manage appointments.

What Are the Different Types of Audio Computer Software?

Audio computer software changed the way consumers perceive music. With these computer programs, consumers went from simply listening to music, to having the ability to listen to, record, or manipulate music files. Different types of audio computer software include players that allow a consumer to listen to different types of music files, recorders that allow consumers to record music, editors that allow consumers to improve or change music files, and converters that allow consumers to change the file type of different music clips.

Music player software is the most common type of audio computer software. With a music player, the owner can play music files directly from a CD, play files stored on his or her computer, or stream music from a website. Many music players also allow the user to create a library of all of their music files within the player itself and to make different playlists using multiple albums.

Recorders have two main functions, including the ability to record from a CD and the ability to record from a voice recorder. The user can use the recording software to transfer his or her CD collection to computer files and store the files within the computer itself. The recording software can also work with a computer's voice recording software, so the user can record his own original music or record streaming music from other sources saving the music as a file on his or her computer.

Editors give the user the most control over his or her music collection, including both music files from other artists and music files of his or her original recordings. This type of auto computer software allows a user to edit different music files using different settings and filters. For example, the user can shorten the length of a file, mix two files together to create a new sound, or add sound effects to an original recording.

A converter is a type of audio computer software that allows the user to change the file type of different music files. Many portable music players only accept one or two file types, such as mp3 or mp4. With a converter, a user can change the file type of all of his music files to match the file type accepted by his portable music player. Some converters also include basic editing features, such as a sharpness filter that removes static or excess noise from the file during conversion.

What Are the Different Types of DJ Computer Software?

Most DJ computer software is designed for use in either playing audio or altering audio in some way to create original compositions by remixing files imported into the program. Audio playback programs can be quite simple, though most DJs prefer somewhat more complicated programs that allow them to create and organize playlists, quickly search through audio files, and play files based on genre. Other types of DJ computer software are designed for altering audio files, usually by creating a remix based on audio content that is altered. Some software can even be used with different types of hardware, such as digital turntables, for “scratching” during playback.

A DJ, or disc jockey, is someone who plays recorded music professionally, such as a radio station DJ or a DJ who works live events like clubs and weddings receptions. DJ computer software is typically designed to assist a DJ with his or her professional work. Most of this software is intended to enhance playback of audio content, and these programs are typically similar to other media player programs. Since these DJ computer software programs are intended for professional use, however, they often have more robust tools for creating playlists, adjusting audio levels during playback, and automixing tracks for particular types of events.

Other types of DJ computer software are created for use in generating original content. Many DJs, especially those who work in clubs, are well known for creating original remixes of existing songs. Software can be used to isolate different parts of a track, especially when using a master recording with multiple channels, to then create new versions of recorded music. This type of DJ computer software allows a DJ to more easily create original remixes that can help the DJ establish a greater presence for himself or herself in a particular scene or industry.

Some DJ computer software can also be used with particular pieces of computer hardware to emulate techniques and methods available to DJs who used traditional equipment. In the past, DJs typically played vinyl records and could alter the sound of recordings during playback through methods such as “scratching.” This is a process by which a vinyl record is physically shifted back and forth around a turntable, allowing the DJ to control how the needle is reading the audio information on the record. Digital technology can be used to replicate this process through hardware that emulates the feel of a turntable, which then communicates with DJ computer software that uses audio time codes to shift playback of the track back and forth while the DJ “scratches.”

What are the Different Types of DJ Equipment?

The thought of DJ equipment conjures up memories of the 1970s disco era, complete with record mixers and a mirrored disco ball. Many of us remember a local disk jockey (DJ) bringing his hodgepodge of DJ equipment to the high school gym for a dance or prom, or to the local American Legion for a wedding or Bar Mitzvah. Like most things, however, DJ equipment has grown and evolved to fit into the high tech world we know today. Gone are the manual flip switches and record changers. Today, one can find DJ equipment that includes just the basics, with a pair of compact disc (CD) decks and a set of speakers, or if money is no object, there are fancy, multi-level CD decks, surround sound amplifier and speaker systems, a professional quality mixer, top notch headphones, and of course, easy access mobile shelving and storage units for CDs.

Today, most DJ equipment is computerized, and some DJs agree that CD decks are becoming a thing of the past. In the same manner as the MP3 player and the iPod, music can now be played with the flip of a switch or the push of a button, without a CD, tape, or record in sight. Often, all that is needed is a computer. A mixer should be included in any set of DJ equipment, because it will allow the sound being output, whether a speaking voice or a song, to play without a break. For instance, a mixer will switch from one song to the next without the momentary silence that usually indicates the end of the song.

A set of good quality headphones is a must in a set of DJ equipment. Most DJs find that a noisy DJ booth can make it difficult to hear the music being mixed. If no booth is available and the DJ finds herself and her DJ equipment practically in the middle of the party or dance, hearing the music clearly is nearly impossible without headphones. The experts agree that headphones in a DJ equipment set should be lightweight and have a closed back to help filter out background noise. Headphones should also have a wide frequency response.

The speakers or amplifier and speakers complete a set of DJ equipment, for they are responsible for carrying the music to the listeners. DJs should make sure that their speakers can handle the volume they plan to use and that the amplifier will properly amplify the signal coming from the computer or CD player. Most DJs who are serious about their music are more than willing to spend the money to purchase high quality DJ equipment, for a DJ who pleases his listeners will be invited back again and again.

How Do I Choose the Best Headphone Mixer?

A headphone mixer is necessary for musicians, especially bands, which need to be able to hear their recorded music to ensure it sounds right and that the mixing is correct, but finding the right headphone mixer can be tough. There must be enough channels so everyone in the band can hear himself or herself simultaneously, and the channels should be able to function independently of each other. The ability to adjust the click track on the fly will help drummers and vocalists the most, because this will turn up or turn down the click so the respective musician can hear his or her part. A mono control will allow each musician to hear an isolated part of the music. Preset controls will help when setting up the mixer, because the user just has to push a button to get the controls ready.

Each headphone mixer comes with at least one channel, depending on the model. The channels allow each person to hear the audio, and the channels themselves typically have controls to change the audio. The best mixer should have enough channels for each band member. It also is best if the channels can function independently, so each musician can hear only his or her part, without the other parts mixing in.

The ability to increase or decrease the click track will be most important for drummers and vocalists, but others also can benefit from this control. Drummers are part of the click track, so they will want a high click to ensure the beat sounds correct and to make it easier to hear just the drums and not the other parts of the song. The other members will likely reduce the click when listening to themselves, because this will make the sound of their instrument or voice clearer.

Mono controls help isolate the audio, so each person can hear only his or her instrument playing. This is typically done either with a button or as one of the headphone mixer settings. Along with isolating the sounds, the bass and treble can usually be controlled as well when the sound is placed in mono.

Setting up the headphone mixer usually is not a difficult process, but it can take several minutes to get the sound just right. To avoid going through this setup procedure, it can help if the headphone mixer comes with preset controls. This will save the control settings, so the users just hit a button and the mixer will be set at its optimal levels.

What is Recording Software?

Recording software creates a digital sound studio for recording and manipulating one or more sound tracks. Tracks can be edited, changed by applying effects, compiled or mixed, matched to video, converted to export formats, or burned to CD or DVD, depending on the program.

Originally, recording software packaged with operating systems had very few options, allowing for recording off the standard Line-In port on any sound card. Plugging a microphone, for example, would allow the user to create a voice recording and save it to a sound file format like WAV on PCs, or AIFF on Macs. Some effects and editing options were included, but today’s recording software — even free programs like Audacity® — have become quite sophisticated.

Audacity®, created by Dominic Mazzoni, is a cross-platform open source program. It’s ability to run on Windows®, Apple®, Linux® and BSD Unix has made it extremely popular. Along with an import feature that supports a generous number of music formats, one can record and mix tracks, apply many types of digital effects, remove noise from a track, and even adjust the tempo without affecting the pitch, handy when matching a track to video. This recording software can also change the pitch of a track without changing its speed.

Another feature found in some recording software, (included in Audacity®), is the ability to automatically create separate files when copying full-length cassettes or vinyl albums. The software separates songs based on the inserted silences between tracks, saving time and hassle when converting music libraries to digital format.

GarageBand® is a highly popular recording software bundled free with Apple® computer systems. Not only does this software support recording and editing, it also includes music lessons by popular artists. Let rock stars like Sting, John Fogerty and Norah Jones teach you how to play one of your favorite songs, then record your own rendition.

Advanced recording software is often bundled with hardware that augments the program. The hardware might be a patch bay, sound card, or both. The patch bay or card commonly features ports for headphones, microphone, and other types of inputs for digital and analog instruments.

Arguably, the most popular commercial program is Pro Tools® by Digidesign®, used extensively in the recording and motion picture industry. This editing and recording software runs on both Mac and PC platforms and comes in three flavors: Pro Tools LE, Pro Tools HD and Pro Tools M-Powered. The LE version is the home version.

All three variations of Pro Tools® use proprietary hardware, without which the software will not function. The high-end versions, HD and M-Powered, use rack-mounted hardware that contain Digital Signal Processing (DSP) chips to facilitate processing of applied digital effects, editing and other functions, along with input for microphones and instruments, both digital and analog. The home version, Pro Tools LE, lacks the rack mount hardware and DSP chips, but does require a proprietary sound card, also used for inputs.

The functionality of recording software like Pro Tools® is probably beyond the needs of the average consumer who wants to edit sound files or record tracks for casual enjoyment. However, for those interested in recording and producing music professionally, in movie scoring or in professional sound editing, a program like Pro Tools® will fit the bill. Check system requirements before purchasing.

Many popular types of recording software are also available in several other packages that fall somewhere between the robust-but-free Audacity®, the fun-loving GarageBand®, and the proprietary Pro Tools. Several programs are available as shareware so you can play with them before deciding. Look for an intuitive interface and the functionality required, without getting a lot of features you’ll never use.

Best Mixing Software

To choose the best mixing software, you should consider what features you want from a program and the value of such a program for you. You should look at the types of audio or video files that any program you are interested in can use, and ensure the software can work with your other programs and hardware. If possible, you might also look for software that offers a free trial so you can see the kinds of features and user interface (UI) included. You might even be able to find a free mixing software program that meets your needs.

Mixing software typically refers to a program that can be used to mix audio or video files together, usually to create output files that combine both original sources. This can be done using different sound files to create a remix, for example, though some programs can also be used to mix audio in real time. Such programs are often used by disc jockeys (DJs) who play recorded music and often mix audio for entertainment at events and in clubs.


As you consider different mixing software, you should look for a program with the features and tools you need. You should, for example, look at the files a program can open or save to, so you ensure the program can work with the files you have. Other features you might look for from mixing software include how the software UI displays the audio files you are working with, what types of editing features are included in the software, and if you can save presets to make live mixing faster and easier.

You should also look at the types of software and hardware that can work with any mixing software you might choose. Most software is developed to work with a particular operating system (OS), so you should ensure that any program you choose is compatible with the OS you use. If you have special input devices, such as a digital turntable, you should look for mixing software that can utilize that equipment.

It can also be beneficial to consider different programs and compare prices between them. You might be able to find freeware that provides you with the mixing features you need. If you are a professional DJ, however, it is likely the mixing software that includes all of the options you want would require a license purchase. The developers of many of these programs offer a free trial, however, so you can ensure any program you choose works best for your needs.
