Detailed Description

template<int Z, int O>
struct rack::dsp::MinBlep< Z, O >

Holds a precomputed minBLEP impulse response, reordered to efficiently insert into an audio buffer.

Constructor & Destructor Documentation

MinBlep()

template<int Z, int O>

rack::dsp::MinBlep< Z, O >::MinBlep ( )

inline

Member Function Documentation

getImpulse()

template<int Z, int O>

const float * rack::dsp::MinBlep< Z, O >::getImpulse ( int o, int z ) const

inline

Get pointer to impulse data, handling o wrapping and z offset.

insertDiscontinuity()

template<int Z, int O>

template<typename T>

void rack::dsp::MinBlep< Z, O >::insertDiscontinuity ( State< T > & s, float p, T x ) const

inline

Places a discontinuity with magnitude x at 0 < p <= 1 relative to the current frame.

For example if a square wave will jump from 1 to -1 in 0.1 frames, use insertDiscontinuity(0.1, -2.0).

Note: In the deprecated MinBlepGenerator, p was in the range (-1, 0], so add 1 to p if updating to MinBlep.

process()

template<int Z, int O>

template<typename T>

T rack::dsp::MinBlep< Z, O >::process ( State< T > & s ) const

inline

Should be called every frame after inserting any discontinuities.

Member Data Documentation

impulseReordered

template<int Z, int O>

float rack::dsp::MinBlep< Z, O >::impulseReordered[O][1+2 *Z+4] = {}

Reordered impulse response for cubic interpolation, minus 1.0.

Z dimension has +1 padding at start (for z-1 wrap) and +4 at end (for SIMD + z+1 wrap). Access via getImpulse() which handles O wrapping and Z offset.
