Audio Technology / Analysis and Delivery/ Introduction...

48,000 Hz or 96,000 Hz /24-bit PCM audio files are not suitable for acoustic analysis or delivery over the Internet. They should be stored as master, preservation copies of the recordings. Such files should be described in commom metadata terms (such as Dublin Core, METS or OLAC) and stored on a dependable optical storage medium, such as CD-R or DVD. The best storage formats are uncompressed, PCM digital audio files, such as Microsoft WAV, The Broadcast Wav Format, or AIFF.
