SideDeck - DJ App & Mixer

SideDeck - DJ App & Mixer

Free, Open‑Source DJ App for Android

• A fully‑featured DJ program you can download at no cost.

• Runs on any Android device with version 8.0 or newer.

• Released under the GNU GPL v3, so there are no hidden subscriptions or “pro” unlocks.

Mix Anywhere – On‑Screen or On‑Hardware

• On‑phone mode – Landscape dual decks with waveforms, a 3‑band EQ, filter, and cross‑fader.

• USB‑mixer mode – Connect a compatible mixer (e.g., Teenage Engineering EP‑136 K.O. Sidekick) and route Deck A and Deck B as separate stereo outputs.

• The app’s internal EQ and cross‑fader step aside, letting you control everything from the hardware.

• Any USB mixer that accepts two independent stereo feeds works the same way.

Your Music, Your Library

• Play tracks stored locally on the device.

• Browse, stream, and download from any Subsonic‑compatible server.

• Automatic BPM and key detection on import; the library highlights tracks that harmonically match what’s already loaded.

FAQ

Q: Which Android versions can run SideDeck, and do I need any special hardware?

A: SideDeck works on any device running Android 8.0 (Oreo) or newer. The on‑screen mode needs nothing more than the touchscreen, while the USB‑mixer mode requires a compatible USB audio mixer that can accept two independent stereo feeds (such as the Teenage Engineering EP‑136 K.O. Sidekick). No root access or additional drivers are required beyond the standard USB audio support built into Android.

Q: Is SideDeck really free, and what does the GPL v3 license mean for me as a user?

A: Yes, SideDeck is completely free to download and use. The GPL v3 license guarantees that you can run, study, modify, and redistribute the software without paying fees or facing usage restrictions. If you modify the app and share your version, you must also provide the source code under the same license, preserving the freedom for everyone.

Q: Can I use SideDeck with my existing music files, and what formats are supported?

A: SideDeck plays any audio file that Android’s media framework can decode, which includes MP3, FLAC, WAV, OGG, AAC, and most common lossless and lossy formats. Simply place your tracks in a folder on the device’s internal storage or SD card, and the app will scan them into its library automatically.
