Re: More than 16 discrete channel labels?

Only QT supports this (rather strange) notion of using a channel label to route a channel to a particular output.

So, in that context, this would "probably" work, but it isn't a broadly supported usage of channel layouts nor would we encourage this usage either.

Hi,

There are constants for for discrete channel labels going from 1 - 16, e.g.,

kAudioChannelLabel_Discrete_0 = (1L<<16) | 0,
kAudioChannelLabel_Discrete_1 = (1L<<16) | 1,
...

But what about discrete channels starting at 16 and above? Can we safely define and use something like this:

kAudioChannelLabel_Discrete_16 = (1L<<16) | 16
kAudioChannelLabel_Discrete_17 = (1L<<16) | 17
etc...

This has come up with a user that wants to be able to get output to the ADAT channels of of his MOTU Traveler. These start at channel 16...

Best Wishes,
Mark
