Which is why I suggested broadcast wav and cart chunk as those are
simply standardised 'chunks'.

Hi all,
For one of my current projects (to be presented at LAC2006) I'm
looking for a suitable file format.
Each file should contain:
- A number of short (+/- 10 seconds) chunks of PCM audio. The number
of channels will be different in each chunk. The only sample format
required is single precision floating point. For multi-channel
chunks, non-interleaved is preferred. All chunks will normally use
the same sample frequency.
- Metadata, both numerical and textual. The format should allow to
have several chunks of these, and to add new ones later without
breaking compatibility (i.e. readers will ignore parts they do
not understand).
There is no need for the audio to be usable with normal players -
it's not meant to be listened to directly.
Is there any standard file/container format that would provide for
this sort of thing ? I've been looking at ogg, but it's a bit over
the top - I don't need any streaming features.
Both WAVE and AIFF are (R)IFF based, so you can put any 'chunks' of
arbitrary data in them and they will still be valid WAVE or AIFF files.
