RtAudioDevice()

MayaFlux::Core::RtAudioDevice::RtAudioDevice

(

RtAudio *

context

)

Initializes the device manager with an RtAudio context.

Parameters

context

Pointer to an active RtAudio instance

Creates a device manager that uses the provided RtAudio context to enumerate and query audio devices. The device lists are populated during construction.
