If using multiple sample rates separate each with a. KSampleRates set the sample rate or sample rates of the audio device. This may be helpful if using BlackHole with a high channel count. It can be used to delay the audio inside of BlackHole up to a maximum of 65536 frames.

KLatency_Frame_Size is how much time in frames that the driver has to process incoming and outgoing audio.

Some applications don't know how to handle high channel counts. Don't use high sample rates with a high number of channels. Although BlackHole is designed to be extremely efficient at higher channel counts it's possible that your computer might not be able to keep up. Be careful when specifying high channel counts. KNumber_Of_Channels is used to set the number of channels. The following pre-compiler constants may be used to easily customize a build of BlackHole.Ĭustomizing Channels, Latency, and Sample Rates

I know it must be write some lines of code in BlackHole_DoIOOperation() function, but I don't know any direction, can anyone give me some suggestion? Thanks When I select this virtual device as audio output device, I do really can capture system output audio through a corresponding virtual input device created by BlockHole at the same time with virtual output device.īut, there is no sound playback from virtual output device, I cannot hear any voice from speaker or headphone. I'm using BlackHole try to capture system output audio on macOS, BlackHole drive can create an virtual audio device, like BlackHole 2ch, which supports 2 channels.
