WASAPI.AttachInputDeviceToPlayer method |
|
Remarks
Attaches an input device (capture or loopback) to a player for immediate playback of incoming audio data.
When the selected input device is a loopback device, this method gives the possibility to mirror the output of a specific render device to a different render device with a very low latency: in this specific case it's strongly recommended that you avoid playing audio data taken from a specific loopback device to the corresponding render device or you may experience a very annoying echo effect.
This method is only intended for usage with Windows Vista and later versions.
