Why convert MP4 to WAV?
If you plan to edit, clean up, or transcribe the audio from a video, WAV is the better extraction target than MP3: it avoids adding a second round of lossy compression before your processing chain. Podcast editors, video editors replacing audio in post, and anyone running noise reduction will get cleaner results starting from WAV.
MP4
The AAC audio inside an MP4 is already lossy; extracting to WAV decodes it once into raw PCM without any further quality loss.
WAV
WAV is uncompressed PCM audio - the universal working format for audio editing software, effects processing, and speech-to-text tools.
Frequently asked questions
Why extract to WAV instead of MP3?
WAV adds no further compression, so it is the right input for editing, mastering, or transcription. Choose MP3 when you just want to listen and care about file size.
How big will the WAV be?
Roughly 10 MB per minute for stereo CD-quality audio, regardless of the video's size. An hour of audio is about 600 MB.
Does this work with screen recordings and phone videos?
Yes - any MP4 with an audio track works, including iPhone/Android recordings and screen captures with microphone audio.
