Member Function Documentation

canProcessAudioFrame()

virtual bool ImpulseConvolver::canProcessAudioFrame ( )

inlinevirtual

return false: this object only processes samples

Implements IAudioSignalProcessor.

init()

void ImpulseConvolver::init ( unsigned int  lengthPowerOfTwo )

inline

create the buffer based on the exact power of 2

processAudioSample()

virtual double ImpulseConvolver::processAudioSample ( double  xn )

inlinevirtual

process one input - note this is CPU intensive as it performs simple linear convolution

Parameters

xn

input

Returns

the processed sample

Implements IAudioSignalProcessor.

reset()

virtual bool ImpulseConvolver::reset ( double  _sampleRate )

inlinevirtual

reset members to initialized state

Implements IAudioSignalProcessor.

setImpulseResponse()

void ImpulseConvolver::setImpulseResponse ( double *  irArray, unsigned int  lengthPowerOfTwo  )

inline

set the impulse response
