Frequently asked questions
Is the audio uploaded to a server?
No. Analysis, conversion and playback use the files in your browser. Only a report and an optional sample chosen by you can be uploaded, after explicit confirmation.
What are the limits?
MP3 and PCM WAV, mono or stereo, between 8 and 48 kHz. Up to 20 MB per file, 40 MB and 3 minutes in total. Output at 44.1 kHz: MP3 or 16-bit PCM WAV. WAV may be larger; MP3 uses lossy compression. Check the result before using it.
Is MP3 trimming exact?
MP3 can add a small amount of audio padding at the start or end. Use WAV when you need precise section duration.
Can already distorted audio be restored?
No. Peak protection reduces the risk of distortion caused by the applied gain; it does not restore distortion already in the recording.
