MP4 vs WAV: Technical Overview
Why Convert MP4 to WAV?
Audio editing and production. Whether you're a YouTuber cleaning up voice audio, a musician sampling your own performance video, a podcaster working from a Zoom recording or an editor preparing a mix, starting from WAV lets you apply noise reduction, EQ, compression and cuts without piling another round of lossy encoding onto the audio.
WAV is also the input format required by many transcription services, speech-to-text engines, broadcast playout systems and sound-design tools. And because WAV is simple and uncompressed, it's a dependable archive format for important recordings.

16-bit PCM at the video's original sample rate, usually 48 kHz, with the original channels.
Why is WAV bigger than MP3?
