One will have inputs only and the other will have outputs only. In this situation we have two BlackHole devices. This is useful if you need a separate device for input and output. The inputs and outputs are mirrored so the outputs from both devices go to the inputs of both devices. When all are set to true a 2nd BlackHole will show up that works exactly the same. The devices may be customized using the following constants. Mirror Deviceīy default BlackHole has a hidden mirrored audio device. If using multiple sample rates separate each with a comma ( ,). 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. GCC_PREPROCESSOR_DEFINITIONS='$GCC_PREPROCESSOR_DEFINITIONSĬustomizing Channels, Latency, and Sample Rates These can specified as pre-compiler constants using xcodebuild. kPlugIn_BundleID (note that this must match the target bundleID).To customize BlackHole it is required to change the following constants. GCC_PREPROCESSOR_DEFINITIONS='$GCC_PREPROCESSOR_DEFINITIONS kSomeConstant=value'īe sure to escape any quotation marks when using strings. They can be specified at build time with xcodebuild using GCC_PREPROCESSOR_DEFINITIONS. The following pre-compiler constants may be used to easily customize a build of BlackHole.
