WAV - WaveForm Audio Format

This section provides basic information on WAV, WaveForm audio format.

What is WAV? WAV is a short name for WaveForm, which is audio file format developed by Microsoft and IBM.

A WAV file name has the file extension of .wav.

The original WAV file format contains uncompressed audio data using the same encoding method, PCM (Pulse-Code Modulation), as audio CDs. So uncompressed WAV file size matches audio track sizes on audio CDs.

WAV files may also be encoded with a variety of codecs (coder and decoder) to compress audio data. A WAV file encoded with the mp3 codec may reduce the audio data to the same level as a MP3 file.

Roughly, uncompressed WAV files takes about 10MB space per 1 minute of play time. Here is how to calculate space requirement based on PCM specifications:

16 bits per sample
44,100 samples per second
60 seconds per minute
2 channels for stereo sound
1 minute stereo sound requires:
2 * 60 * 44,100 * 16 bits
   = 2 * 60 * 44,100 * 2 bytes
   = 10,584,000 bytes = 10 MB
