Remarks
Starts a recording session from the WASAPI input mixer which gets and mixes PCM data incoming from capture and loopback devices attached to the mixer through previous calls to the WASAPI.MixerInputDeviceAttach method.
Calling this method will cause the control to fire a RecordingStarted event. The recording session can be stopped at any time through a call to the Stop method.
This method is only intended for usage with Windows Vista and later versions.
For further details about the use of WASAPI see the WASAPI object and the How to manage audio flow through WASAPI tutorial.
For details about the encoding format and parameters applied during recording see the How to perform a recording session section.
