Uncompressed WAV files are quite large in size, so as file sharing over the internet has become popular, the WAV format has declined in popularity. (sample rate) * (bit depth) * (number of channels) = kbits per secondįor example, 44 100 Hz, 16 bit stereo equates to (44 100 * 16 * 2) = 1411 kbps.

Bit rate for WAV and AIFF is calculated thus: The bit rate of MP3 can be compared with the much higher rates used in WAV and AIFF. An MP3 exported from Audacity at its default 128 kbps bit rate uses about 1 MB of space per minute for either a mono or stereo file. A compressed, lossy format like MP3 takes much less space. In comparison, some modern formats such as FLAC which are compressed but still lossless, take about 4 MB of space per minute for a comparable file. This 'audio CD' standard consumes approximately 10 MB of disk space on a computer for each minute of audio. PCM is the format standard of audio CDs, conveying two channels with a sample rate of 44,100 Hz (samples per second), and a bit depth of 16 bits per sample. While the RIFF format can act as a container for various audio compression codecs, more typically it contains uncompressed pulse-code modulation ( PCM ) audio that retains all the samples of the original signal, and is thus known as 'lossless'. WAV files always have little-endian byte order whereas the original AIFF format was big-endian until Apple modified it for use on their OS X/macOS operating systems. WAVs and AIFFs are in general equally compatible with either Windows and Macintosh operating systems. It is thus similar to both the IFF and AIFF formats used on Amiga and Apple Macintosh computers respectively. WAV is a variant of the RIFF bitstream format method for storing data in 'chunks'. 3 Compressed WAVs from portable recorders.
