Upload your files
Drag and drop two audio files to compare. Supports WAV, MP3, FLAC, AAC, and OGG.

Why A/B Test Audio Files?
Producers, engineers, and musicians use audio diff tools to catch differences the ear alone can miss
Compare mix revisions
Upload your latest mix and the previous version to hear exactly what changed. Compare mix versions side by side before sending to your client.
Check mastering results
A/B test the pre-master and mastered file to evaluate EQ, compression, and loudness changes.
Evaluate format conversions
Compare a WAV original against an MP3 or AAC export to hear what the codec discards.
