Questions about WAV
What is a WAV file?
WAV holds raw uncompressed PCM audio: nothing is thrown away, nothing is guessed on playback. It is the format audio editors and mastering tools want, and it is far too heavy to send around casually. It is the RIFF / WAVE container, usually holding Uncompressed PCM.
Is converting WAV free?
Yes. Convert and preview for free, then create a free account to download the result. Nothing is installed and there is no watermark on the file itself.
Will converting to WAV lose quality?
Some, whenever the codec changes: every re-encode discards detail. Where the container can simply be rewritten around the existing streams it is lossless, and where it cannot the default settings are chosen so the loss is not visible at normal viewing size.
