The portion of the file holding the audio data. The audio data might be compressed to save disk space. The data has to be decompressed using an audio decompressor before you can play (hear) it.

oftware component which decompresses audio. It must be designed to work with ACM or DirectShow . Note that different compression methods require different decompressors. There is no universal decompressor capable of decoding all compressed streams.
