What's new

The changes in each release that you would notice using it, newest first.

0.7.0 14 October 2026

A Linux version, as an AppImage that runs on most 64-bit distributions.
Recordings that come in several files open as one. Recorders often split a long recording at 2 or 4 GB; select all the parts, or drop them on the window together. Parts the recorder numbered are joined in the order of their numbers, others in the order they were written. The recording shows as one entry, named like "REC00*.WAV (3 files)".

Mark a mix by ear. I and O put the start and the end of the mix at the playhead, and Cmd/Ctrl+E splits it there. Buttons in the mix row do the same.
Cuts to the millisecond. Edges and splits land exactly on the playhead, in the app and in the exported files.
The real waveform close up. Zoom in down to half a second across the window; from 20 seconds inwards the waveform is drawn from the sound itself, so single beats and bass notes can be seen.
Run through a mix at speed with J, K and L: L plays forwards and each press doubles the speed, J runs backwards (silently), K stops.
Double-click a free part of the recording to fill it with a new mix.
Deleting the only mix sets it back to the whole recording.
Marking and cutting keep the zoom where it is. Playback stops at the end of a mix; pressing play there starts the mix over.
A recording that has been moved or renamed keeps its mixes, and is not analysed again.
Long mixes respond about twice as fast to a change of setting.

A level meter beside the curves: left and right with the peak held, a column that lights when the limiter works, a lamp for clipping in the recording, and the loudness, gain and bass change at the playhead.
Starts where you left off, with the recording that was open last. File → Open Recent and the start screen list the recordings you used lately; File → Close Recording puts one away.
The check-up also finds mains hum (50 or 60 Hz), rumble and a DC offset.
A row of transport buttons, quicker tooltips, and a sheet of all gestures and shortcuts (the ? button, or ? or F1).
Smaller icon buttons for undo, redo and the mix tools. Backspace deletes the selected mix, or the hand adjustment under the pointer.
Peaks the limiter holds down are shown in amber; red is kept for clipping.
The legends on the curves stay faint until pointed at.

A check-up of the recording when it is opened: clipping, a missing, weak or out-of-phase channel, a recording that is really mono, possible dropouts, a very quiet recording, and a source that was compressed.
Lets you know when a newer version is out. It looks at most once a day, gives up quickly without an internet connection, and can be switched off in the Help menu. Nothing about your recordings leaves the computer.
"Apply to all mixes" gives every mix in a recording the same settings.

Fades at the start and end of a mix: drag a corner of the waveform inwards.
Loudness presets for where a mix is going: Loud (-9 LUFS) for places that play files as they are, Streaming (-14), Podcast or radio show (-16) and Broadcast (-23).
DJ Mix Master is now free software, under the GPL, with a website.

An export dialog: WAV, FLAC, MP3 or AAC, with the bit depth, bitrate and sample rate. 16-bit files are dithered.
Exports carry a title, artist, album and track number, and MP3 and AAC files get a little room so that they do not clip when played.
Hand adjustments can move the bass alone.

The first release.

Evens out the loudness between the tracks of a recorded DJ mix: louder tracks come down, quieter ones come up, and breakdowns keep their dip.
Bass correction levels the kick and bass between tracks separately from everything above them.
Made for whole nights: mark several mixes in one recording, zoom and scroll through hours of it, and split it at the silences between sets.
As loud as fits: the automatic level stays clear of the limiter, even on a recording that was made too hot.
Hear it first: the preview uses the same true-peak limiter as the export, and switches between the original and the levelled sound.
Raise or lower any stretch by hand.
Your mixes, settings and adjustments are remembered per recording, with undo and redo.
Exports are named after their mix; analysing and exporting can be cancelled.
Installers for Macs with Apple Silicon and for Windows.
