This is an audio codec. The name to use at the command line is raw. This codec is from the araw module. |
VLC's raw codec decodes raw audio data in the PCM format.
Pulse-code modulation or PCM is the simplest way of storing audio data. At regular time intervals the audio is sampled, and the amplitude is stored.
PCM is the basis for WAVE audio files.
Fourcc
The following fourccs are used for this codec:
- araw
- "pcm "
- aflt
- twos
- sowt
- alaw
- ulaw
- fl64
- fl32
- s32l
- s32b
