DJ Mixer Pro - 2 Deck DJ App

DJ Mixer Pro is a DJ app that plays the songs already on your phone across two decks so you can mix from one track into the next. Auto BPM detection and SYNC line up tempo and beats, and the 3-band EQ and crossfader blend them smoothly. Songs are decoded on your device, so playback needs no internet connection. Record your finished mix straight to WAV.

Mixing on two decks and recording your set are free. Extra effects, key lock, auto mix and more come with Premium, a one-time purchase.

KEY FEATURES

■ Two decks and waveforms
Load a song on each deck. The scrolling waveform is colored by lows, mids and highs, so you can see kicks and breakdowns coming. Jump anywhere from the full-track overview; while playing, hold first so you never skip by accident.

■ BPM detection and SYNC
Each song's BPM and first beat are analyzed automatically to build a beat grid. Press SYNC to keep a deck locked to the other deck's tempo and beat position, even for double- or half-time tracks. Fix a wrong BPM with ×2, ÷2, tap tempo or by typing it, nudge the grid in 10 ms steps, or set the downbeat right where you are.

■ Jog wheel and pitch
In vinyl mode, touching the jog scratches; turn it off to nudge the speed instead. Choose a pitch range from ±6% to ±50% and use the bend buttons to beatmatch by ear.

■ Mixer
Each channel has gain, a 3-band EQ, a filter, a fader and a level meter. Long-press an EQ knob to kill that band instantly, perfect for the classic bass swap. Pick a smooth, medium or sharp crossfader curve; a master limiter prevents clipping.

■ Headphone CUE (split output)
Preview the next song in your headphones before the crowd hears it. With split output, left is the master for the speakers and right is your headphones (use a splitter cable).

■ Hot cues, loops and beat jump
Set up to 4 hot cues per deck and jump to them with a tap (long-press to clear). Make loops with IN/OUT or one tap from 1/4 to 32 beats, then halve or double them. Beat jump moves 1, 4, 16 or 32 beats back or forward.

■ Effects and sampler
Echo and reverb are included. The sampler has 15 built-in sounds such as air horn, siren, laser, kick, clap and riser, all synthesized inside the app, with four free pads.

■ Record and share
Press REC to record the master output. WAV recordings have no time limit and no watermark. Play, rename, share or save them to your device.

■ Library
Browse songs, folders, playlists, history and files, add audio files from device or cloud storage, search, and sort by title, artist, BPM, key or length.

■ Low latency
Choose Fast or Stable response; the buffer widens automatically if dropouts occur. Sound diagnostics show latency, dropouts and the output device, and you are warned when laggy Bluetooth audio is connected.

■ Background playback
Your mix keeps playing in the background and stops from the notification. It pauses when headphones are unplugged or a call comes in.

Premium is a one-time purchase that is yours for good. It is not a subscription. On a new phone, use Restore purchase with the same Google account.

SUPPORTED FILES
MP3, AAC/M4A, FLAC, WAV, OGG and Opus. DRM-protected songs and songs from streaming services cannot be loaded.

TIP
CUE and beatmatching depend on audio delay. For DJing, use wired earphones or the phone speaker.
