ReSoul: Audio Mastering

Finish your track without uploading it. Smart Master offers a starting point; measured export reports show what you delivered. No per-track fees.

Turn your stereo mix into a finished master, with the measurements to understand what you delivered.

Import a track, choose a starting point and shape the sound. ReSoul keeps analysis, mastering and export on your device.

START WITH THE SONG Smart Master analyzes your track and suggests a restrained starting point. Explore genre profiles or take control of the mastering deck yourself.

HEAR YOUR DECISIONS Compare Before and After while adjusting tone, dynamics and stereo character. Waveforms, spectrum and loudness meters help you see what changes.

CHECK THE FILE YOU DELIVER Export 24-bit WAV, MP3 or AAC/M4A. ReSoul checks the completed file and reports its loudness and true peak, with measurements for the selected format.

The live After signal is a processing preview. Export applies the full mastering chain and verifies the delivered file, so the export report is the record of the final result.

MADE BY PHOTOGRAPHERS, BACKED BY SCIENCE A shared maker philosophy, applied here to music: creative judgment supported by signal processing and loudness measurement. The Pacific Northwest photography in the listing is the developer's own work.

Import unprotected WAV, AIFF, FLAC, MP3 or M4A files. Protected streaming-library tracks are not supported.

One purchase for iPhone, iPad and Mac includes unlimited exports. No subscription, account or additional export unlock.
