How to convert MP4 to WAV with Windows Media Player

Part 5 Extended Knowledge About WAV

WAV's full name is Waveform Audio File Format(WAVE), at times named Audio for Windows, one of the applications of Resource Interchange File Format (RIFF). It's developed jointly by Microsoft and IBM for storing audio bitstream on PCs, supportable by nearly all Windows audio hardware/programs like Windows Media Player.

WAV is the typically format of raw/uncompressed audio on Windows, and can also contain compressed audio with high quality. It rivals CD audio in quality such as 44.1 KHz sample rate, 16-bit bit rate. In spite of this, a .wav file usually is much larger than common audio formats, even lossless FLAC and APE. But TV, radio, DVD or any other media requiring top uncompromised audio quality often use WAV files like BBC Radio to deliver a perfect loop.
