Methods

void allocateStreamData (int numInputs, int numOutputs)

Allocate stream data arrays for specified number of I/Os.

void deallocateStreamData ()

Deallocate stream data arrays.

void allocateStreams (
    int numInputs,
    int numOutputs,
    int maxChannels = kMaxAudioStreamChannels
)

Allocate stream arrays and audio buffer arrays for specified number of I/Os.

Calls allocateStreamData.

void deallocateStreams ()

Deallocate stream arrays and audio buffer arrays.

Calls deallocateStreamData.

void setInputStreamBuffers (int index, float32* buffers [], int numChannels)

Assign buffer addresses for given input stream.

void setOutputStreamBuffers (int index, float32* buffers [], int numChannels)

Assign buffer addresses for given output stream.
