Syntax
struct FPatchOutput
Remarks
This class can be thought of as an output for a single constructed instance of FPatchInput. Each FPatchOutput can only be connected to one FPatchInput. To route multiple outputs, see FPatchSplitter. To route multiple inputs, see FPatchMixer.
Example usage:
FPatchOutputStrongPtr NewOutput(new FPatchOutput(4096)); FPatchInput NewInput(NewOutput);
// On one thread, push audio to the output: NewInput.PushAudio(AudioBufferPtr, AudioBufferNumSamples);
// and on a seperate thread, retrieve the audio: NewOutput->PopAudio(OutAudioBufferPtr, AudioBufferNumSamples);
