RemarksMicrosoft defines more than 130 different audio encoding formats for WAVE files. Only the more common formats are defined here.
Note that PCM (i.e., Pulse Code Modulation) is a universal audio encoding format. It is a very common method of storing and transmitting uncompressed digital audio. Since it is a generic format, it can be read by most any audio application similar to the way a plain text file can be read by any word-processing program. PCM is used by Audio CDs and digital audio tapes (DATs). PCM is also a very common format for AIFF and WAV files.
