Detailed Description
Audio data to be sent to callback Audio buffers are guaranteed to be stored in a contiguous non-interleaved format, i.e., frames are tightly packed per channel.

◆ channels()
|
virtual |
Sets number of effective channels on input or output device depending on 'forOutput' flag. An effective channel is either a real device channel or virtual channel depending on how many channels the device supports. Passing in -1 for the number of channels opens all available channels.
