About MP4 to WAV
Editing the sound of a video, or feeding it to transcription software? Most audio tools prefer WAV. This converter pulls the audio out of your MP4 and stores it uncompressed.
No extra quality is lost in the process, which matters if you'll edit and export again. The video is processed in your browser and isn't uploaded.
The WAV holds exactly the sound of the video, from start to finish, with the same number of channels. Uncompressed sound takes space: about 10 MB per minute in stereo, so an hour of video gives a WAV of around 600 MB. For listening rather than editing, MP4 to MP3 makes a much smaller file.
Transcription services and audio editors such as Audacity, Audition and Reaper open WAV without any extra codecs. If the MP4 has no sound track, you get a clear message instead of an empty file. Your video is never uploaded, which matters for recordings of meetings and interviews.
