Comparing audio
Hear exactly what changed between two takes, two edits or two exports of a recording. The replica is silent, but everything else works.
Choose two recordings and they are compared as sound. The column heads give each one’s length, sample rate and channels.

It works: try the buttons. Hover to find the parts the steps explain, and click one to jump to it.
What it reads
| Format | Files | Good to know |
|---|---|---|
| WAV | .wav | Uncompressed, the most exact comparison. |
| MP3, M4A/AAC | .mp3 .m4a .aac | Compressed formats are decoded by your browser first. |
| Ogg, Opus, FLAC | .ogg .oga .opus .flac | |
| WebM | .webm | Audio only. |
Tips
- Mixed formats are fineA WAV can be compared with an M4A of the same take. Both are decoded by your browser before comparing.
- Speech and musicThe alignment works on any sound. The transcript is for speech, and works best on clear recordings.
- KeyboardN and P step through the differences, and 1 to 3 switch between waveform, spectrogram and loudness.
Try the audio samples: two takes of a spoken sentence, the same takes as WAV and M4A, and a short tune with one note changed.
