Detailed Description

Bpm/beat based loop roll effect.

One instance allocates around 1600 kb memory.

Constructor & Destructor Documentation

Roll() [1/2]

Superpowered::Roll::Roll	(	unsigned int	samplerate,
		unsigned int	maximumSamplerate = 96000
	)

Constructor.

Enabled is false by default.

Parameters

samplerate	The initial sample rate in Hz.
maximumSamplerate	The maximum sample rate in Hz to support. The higher the larger the memory usage.

~Roll()

Superpowered::Roll::~Roll

(

)

Roll() [2/2]

Superpowered::Roll::Roll ( const Roll &  )

private

Member Function Documentation

operator=()

Roll& Superpowered::Roll::operator= ( const Roll &  )

private

process()

bool Superpowered::Roll::process ( float *  input, float *  output, unsigned int  numberOfFrames  )

virtual

Processes the audio.

Always call it in the audio processing callback, regardless if the effect is enabled or not for smooth, audio-artifact free operation. It's never blocking for real-time usage. You can change all properties on any thread, concurrently with process().

Returns

If process() returns with true, the contents of output are replaced with the audio output. If process() returns with false, the contents of output are not changed.

Parameters

input	Pointer to floating point numbers. 32-bit interleaved stereo input.
output	Pointer to floating point numbers. 32-bit interleaved stereo output. Can point to the same location with input (in-place processing).
numberOfFrames	Number of frames to process. Recommendations for best performance: minimum 64.

Implements Superpowered::FX.
