ARMovie

ARMovie is a RISC OS native video format which is occasionally used for sound-only storage. PlayIt can play the soundtrack for such files whether or not video data is also present.

Filetype | &AE7 (ARMovie)
Channels | Mono/Stereo
Rates | Any
Subformats | 8-bit signed and unsigned linear
| 16-bit signed and unsigned linear (little endian)
| 8-bit VIDC
| Others via special codecs (see below)
Annotation | Name, Artist and Copyright

ARMovie has the rather nasty feature of being being able to specify a sound format using a named codec which makes the job of a 3rd party player like PlayIt more difficult. PlayIt recognises the following codec names and can play them:

msadpcm | 4-bit Microsoft ADPCM (little endian)
adpcm | 4-bit IMA ADPCM (little endian)
lin16bes | 16-bit signed linear (big-endian)
lin16be | 16-bit unsigned linear (big-endian)
alaw | 8-bit A-law
mulaw | 8-bit µ-law
