Mirror Deviceīy default BlackHole has a hidden mirrored audio device. 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.
