multiple audio channels represented in a single track

Hi,

Is it possible to have multiple audio channels in a single track, with the individual samples interleaved,
in a Quicktime file?
In other words, can the SoundDescriptionV2 numAudioChannels field be set to greater than 1 (up to 8) ?


So the data would be organized frame by frame together in the Quicktime file:

(for example, 8 channel audio)
a single channel 1 sample, followed by
a single channel 2 sample, followed by
a single channel 3 sample, followed by
a single channel 4 sample, followed by
a single channel 5 sample, followed by
a single channel 6 sample, followed by
a single channel 7 sample, followed by
a single channel 8 sample, followed by

the next channel 1 sample, followed by
the next channel 2 sample, etc

All the audio would then correspond to a single track in the Quicktime wrapper.

Is this permissible?

Thanks, Tommy Schell
