Can I DJ with my phone?

DJing involves playing and mixing recorded music for an audience. DJs typically use various pieces of equipment like turntables, CD players, mixers, laptops, and DJ controllers to cue up tracks, adjust songs to the same tempo, mix between tracks, add effects, and more. The origin of DJing dates back to the 1970s in New York City when DJs like Kool Herc would isolate and extend the instrumental breaks in funk and disco records by switching between two turntables. This developed into hip hop music.

Over the decades, DJ equipment evolved from just turntables and a mixer to add in samplers, drum machines, synthesizers, laptops, and advanced DJ controllers. While vinyl records were once the main medium, CDs and digital files on laptops and controllers now dominate DJ booths. The core concept remains mixing tracks seamlessly using a mixer with crossfader and channel faders along with turntables or media players. Modern DJ setups combine this classic gear with laptops, MIDI controllers, effects processors, and more for creative live mixing and remixing.

Using a Phone as a Music Player

One of the most basic ways to use a phone for DJing is to simply play music directly from the device through a PA system or speakers. Most smartphones come preloaded with a default music player app like Apple Music or Google Play Music which allows you to access songs stored locally on your device. You can create playlists and cue up tracks to play just like you would with a traditional DJ setup.

There are also many third party music player apps designed specifically for DJs, like Pulselocker and DJay, that offer advanced DJ-friendly features for mixing and crossfading. These apps often include beat matching, pitch control, looping, effects, and allow you to set cue points for easy transitions between songs.

The main advantage of using a phone as your music player is convenience and portability. You can load up all your tracks onto a device that fits in your pocket. However, local storage is limited compared to laptops or CDJs, so you may need to swap out songs if your library is large.

Using DJ Apps

Mobile DJ apps like Edjing Mix, Cross DJ, and DJay Pro allow you to DJ and mix tracks directly on your smartphone or tablet. These apps provide mixing decks, EQs, effects, looping, beatmatching, and other standard DJ features. Most apps include sizable libraries of songs and let you import your own music library. This allows you to access thousands of tracks without carrying around physical media.

However, mobile DJ apps have some limitations compared to professional DJ software and hardware. The small touchscreens don’t allow the same level of precision and control. Effects and transitions may be more basic. The audio quality and processing power is reduced compared to a laptop or DJ controller. Long, continuous mixing sessions may cause phones to overheat. And if your phone’s battery dies, the party is over.

For casual DJing, short sets, or emergency backup, mobile DJ apps offer a capable solution right on your smartphone. But for professional, seamless, uninterrupted DJ sets, dedicated DJ gear remains the top choice.

Connecting Controllers

One of the biggest limitations of DJing directly on a phone is the small touchscreen interface. While swiping and tapping to mix tracks can work in a pinch, most DJs are more comfortable with physical controllers and interfaces. Thankfully, there are options for connecting external DJ controllers and hardware to your smartphone.

Some controllers like the Pioneer DDJ-200 or Numark Party Mix can connect directly to your phone via USB. This allows you to use the traditional DJ controls like jog wheels, faders, knobs, and buttons to control the software and mix your music. The controllers essentially turn your phone into a digital DJ setup.

There are also small USB audio interfaces like the Hercules DJUCED 40 that can provide headphone and speaker outputs for your phone. This lets you plug in proper DJ headphones and speakers to your phone for better monitoring and sound quality.

For more professional controllers, you may need an adapter like the Rane GO or a powered USB hub to provide enough power and inputs to connect them to your phone. With the right gear, you can unlock the full capabilities of a pro DJ controller using only a smartphone.

While phone screens are small, connecting an external monitor can also make it easier to view your DJ software. This allows you to see waveforms, libraries, and more as if you were using DJ software on a laptop or computer.

Live Streaming Sets

Streaming live DJ sets directly from your phone has become increasingly popular, especially with the growth of platforms like Twitch, YouTube, and Facebook Live. With just a phone, a good mobile data/WiFi connection, and the right apps or equipment, DJs can now broadcast their mixes to a potentially huge audience.

Dedicated apps like Roland GO:Mixer allow you to connect turntables, mixers, and controllers directly to your phone via cables or Bluetooth to capture the audio. The app then encodes it in real-time and streams it to your platform of choice. For basic streaming, your phone’s built-in mic can also work in a pinch.

Extra equipment like portable webcams, lighting rigs, and mobile tripods can further enhance the production value of your phone-based live stream. However, the audio quality captured directly from your DJ gear and the ability to mix tracks remains the core component.

With preparation and practice, streaming DJ sets solely from a smartphone provides flexibility and portability beyond hauling heavy laptops and equipment. Just be aware of data usage and internet connectivity challenges. For professional and reliable results, dedicated streaming gear is still recommended.

Mixing Limitations

While it’s possible to mix music using only a smartphone, there are some notable limitations compared to using proper DJ equipment and software. Phones have smaller screens which can make it more difficult to view waveforms when beatmatching and mixing. The processing power and audio capabilities of phones are also limited compared to professional DJ gear. This can make EQing and audio effects less responsive.

Most mobile DJ apps provide only basic 2-channel mixing capabilities, while professional DJ mixers and controllers offer 4 or more channels for more creative mixing. The crossfader and volume faders on phones are also virtual and less tactile compared to hardware DJ mixers. Additionally, mixing on small touchscreens lacks the physical feedback needed for smooth beatmatching.

According to Digital DJ Tips, beatmatching and smooth mixing is noticeably harder when relying solely on a phone’s small interface. For serious DJs doing live performances, having dedicated DJ hardware and software is recommended over only using a smartphone.

Audio Quality Concerns

When using a phone for DJing, one potential drawback is that phones may not output the highest audio quality, especially when connecting to large speaker systems. Phones are designed mostly for personal listening through headphones or small built-in speakers.

DJs generally prefer using uncompressed, high-quality audio formats like WAV or AIFF files rather than compressed formats like MP3s or AAC files. According to experts, 320kbps MP3s are often sufficient for most DJ purposes, but lower bitrates may result in degraded sound quality on big systems (Some sources: https://www.digitaldjtips.com/is-it-still-ok-for-djs-to-play-mp3s/, https://djcity.com.au/blog/what-is-the-best-audio-format-for-djs/).

While phones can typically play uncompressed audio files, their built-in DACs (digital-to-analog converters) and amplifiers may not produce the highest fidelity output compared to professional DJ gear. This becomes more noticeable when phones are hooked up to venue sound systems or large PA speakers. The audio conversion and amplification hardware in phones is designed for personal listening rather than professional audio playback.

For critical DJ gigs where audio quality matters, phones should be tested thoroughly to ensure they can provide satisfactory sound without distortion or degradation of dynamics and frequency response. For more casual personal use, phone audio capabilities are likely sufficient.

Small Gigs/House Parties

While professional DJs rely on industry-standard equipment for live shows and events, using a phone can work well for small, informal gigs like house parties. Phones are portable and convenient to carry around. Most people already have their phone with them, making it easy to quickly set up some tunes anywhere. With a phone, an impromptu dance party can break out wherever you are. At small house parties with friends, a phone has enough power to provide background music. Provided the phone is connected to decent speakers, the sound quality is sufficient for a casual party atmosphere. Using a phone to DJ allows anyone to take a turn playing music from their own device and personal playlists. It creates a relaxed, collaborative vibe as friends take turns DJing from their phones.

Use as Emergency Backup

One important reason for a DJ to keep some music files on their phone is to use it as an emergency backup. If your main DJ equipment or laptop fails for some reason during a gig, having a phone with some key tracks loaded up can be a lifesaver.

As suggested in the DJ Tips video on using phones as emergency backup, having an iTunes library loaded on your iPhone with special or must-play songs is a good idea. That way if your main rig crashes, you can plug your phone into the sound system and play those crucial tracks to keep the party going.

You may not be able to beatmatch and transition as smoothly when using just a phone. But in an emergency, it’s better than silence. Having a prepared emergency backup on your phone can give you time to troubleshoot issues or switch to a secondary laptop if needed.

Conclusion

Using a phone or tablet for DJing offers both advantages and disadvantages. While mobile devices provide convenience, portability, and an easy entry point into DJing, they lack the tactile control, audio connectivity, and robust performance of traditional DJ gear. For casual DJs or beginners, a mobile device can be a fun way to mix music and try DJing. But for serious, professional DJ work, most will prefer the specialized hardware and software found in DJ controllers, mixers, turntables, and laptops. In the end, DJing with a phone has its place, but dedicated DJ gear remains the preferred choice for refined mixes, reliable gigs, and optimal audio quality.

To wrap up, phones allow nearly anyone to try basic DJing thanks to DJ apps and streaming music services. While limitations exist, mobile DJing offers a portable and accessible option in a pinch. Yet for pro-level performance, traditional DJ controllers provide superior results. With both options now available, DJs can choose the experience that fits their needs and goals.
