Mini Audition
A waveform that keeps up
Drawn with Metal: from a whole album down to individual samples, smoothly, with RMS shading, an overview strip and a spectrogram one keystroke away.
Hear it. Cut it. Mix it.
A small, fast audio editor for the Mac. Open a pile of tracks, zoom down to single samples, record, arrange them on a multitrack with buses and effects, and bounce a mix — without the weight of a full DAW.
Free · Version 5.0 · macOS 15 or later · Apple silicon and Intel · Signed and notarized
Everything you reach for. Nothing you don't.
Multitrack and mixer
Drag tracks onto lanes, trim, split and crossfade clips, route them through coloured buses with effect chains, then mix down to a new track.
Record in place
A live waveform as you record, or a take straight onto a new lane while the mix plays — lined up with what you heard.
Effects you can hear
Parametric EQ, compressor, limiter, gate, delay, chorus, reverb and more, with presets and a live preview while it plays. Bypass any of them to compare.
Transcripts, on device
Transcribe in 47 languages with clickable timestamps; get a title, a summary and regions by topic from Apple Intelligence. Nothing leaves your Mac.
Sessions with a memory
One file with every track, edit and mix — and a snapshot at every save, with a picture of the window, to go back to any earlier state.
Small app. Serious insides.

Metal all the way down
The waveform, the spectrogram (its FFT included) and the spectrum analyzer are GPU shaders, so zooming from hours down to single samples stays smooth.
Real-time audio, done right
Playback streams from memory through AVAudioSourceNode. The render
thread never locks or allocates; effects and meters hand over lock-free.
In step with your ears
Meters, the analyzer and recorded takes are lined up with the output's latency — even the quarter second AirPods add.
Native, nothing else
Swift 6 with strict concurrency, SwiftUI and AppKit. No Electron, no web views, no runtime to install. One universal app for Apple silicon and Intel.
Private by design
Transcripts come from Apple's on-device speech recognition, summaries from Apple Intelligence's on-device model. Your audio stays on your Mac.
Originals stay untouched
Edits are kept as lossless 32-bit float until you export, and every edit — audio, markers, the mix — can be undone.
