Raw audio format

File format for uncompressed audio

A raw audio file is any file containing un-containerized and uncompressed audio. The data is stored as raw pulse-code modulation (PCM) values without any metadata header information (such as sampling rate, bit depth, endian, or number of channels).

Extensions

Raw files can have a wide range of file extensions, common ones being .raw, .pcm, or .sam. They can also have no extension.

Playing

As there is no header, compatible audio players require information from the user that would normally be stored in a header, such as the encoding, sample rate, number of bits used per sample, and the number of channels.
