Does converting WEBM to WAV lose quality?
The soundtrack is decoded and stored as WAV, which is uncompressed. Nothing more is lost in the conversion, but the WAV cannot be better than the audio that was inside the video.
How long does it take?
Fast. Only the sound is decoded, so even a long video usually converts in well under a minute.
What is a WEBM file?
WebM is an open, royalty-free video format made by Google for the web. It is based on Matroska and uses VP8, VP9 or AV1 video with Opus or Vorbis audio. Browsers play it natively, and many screen recorders and download tools produce WebM files.
What is a WAV file?
WAV usually stores raw, uncompressed PCM audio, the same data as an audio CD. Quality is perfect but files are large: about 10 MB per minute of CD-quality stereo.
