Member Function Documentation

apply_to_buffer() [1/2]

template<typename SampleType = float>

void pulp::signal::AdsrT< SampleType >::apply_to_buffer ( SampleType * buffer, int start_sample, int num_samples )

inline

Multiply num_samples of buffer (starting at start_sample) by successive envelope values.

Advances the envelope by num_samples. Real-time safe; no allocations.

adsr.apply_to_buffer(audio_data, 0, block_size);  // amplitude envelope

apply_to_buffer() [2/2]

template<typename SampleType = float>

void pulp::signal::AdsrT< SampleType >::apply_to_buffer ( SampleType *const * channels, int num_channels, int start_sample, int num_samples )

inline

Multiply each channel of a planar multi-channel buffer by the same envelope.

All channels see the same envelope progression — the envelope advances once per sample, not per (sample, channel) pair.

is_active()

template<typename SampleType = float>

bool pulp::signal::AdsrT< SampleType >::is_active ( ) const

inline

next()

template<typename SampleType = float>

SampleType pulp::signal::AdsrT< SampleType >::next ( )

inline

note_on()

template<typename SampleType = float>
