Note that some CoreAudio devices like the Roland UH30 look -like one device but are actually two different CoreAudio devices. The -BuiltIn audio is typically one CoreAudio device. - -Mono doesn't work. - -DEVICE MAPPING - -CoreAudio devices can support both input and output. But the sample -rates supported may be different. So we have map one or two PortAudio -device to each CoreAudio device depending on whether it supports -input, output or both. - -When we query devices, we first get a list of CoreAudio devices. Then -we scan the list and add a PortAudio device for each CoreAudio device -that supports input. Then we make a scan for output devices. |
