MP4/M4V to WAV: Extract Audio from MP4/M4V(MPEG-4 Video) Video to WAV(Waveform) with River Past Audio Converter, MP4/M4V2WAV converter, conversion

What is MP4/M4V?

A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

There are several ways to decode MP4 video. Most of the time, having Apple QuickTime installed is sufficient. Occasionally, a file is not compatible with QuickTime. You will need to install CCCP when that happens.

What is WAV?

The format for storing sound in files developed jointly by Microsoft and IBM. Support for WAV files was built into Windows 95 making it the de facto standard for sound on PCs. WAV sound files end with a.wav extension and can be played by nearly all Windows applications that support sound.
