Frequently asked questions

Why is the WAV file so big?

WAV is uncompressed: about 10 MB per minute of stereo audio. That is normal and is why it is used for editing, not for sharing.

Does WAV improve the audio quality?

No. It keeps the quality of the audio in your video exactly, without adding any new compression.

Should I use WAV or MP3?

Use WAV for editing and processing, MP3 for listening and sharing.

Is my file private?

Yes, it is deleted automatically 60 minutes after processing.
