inline

Port: master fader level [0,1].

ret() [1/2]

template<uint16_t MaxFrames, uint8_t NumAudio, uint8_t NumReturn, uint8_t MaxSends = 4>

Chan & sbl::dsp::modules::Mixer< MaxFrames, NumAudio, NumReturn, MaxSends >::ret ( uint8_t  idx )

inline

Access a return channel by index.

Definition at line 85 of file mixer.hpp.

ret() [2/2]

template<uint16_t MaxFrames, uint8_t NumAudio, uint8_t NumReturn, uint8_t MaxSends = 4>

const Chan & sbl::dsp::modules::Mixer< MaxFrames, NumAudio, NumReturn, MaxSends >::ret ( uint8_t  idx ) const

inline

set_return_processor()

template<uint16_t MaxFrames, uint8_t NumAudio, uint8_t NumReturn, uint8_t MaxSends = 4>

void sbl::dsp::modules::Mixer< MaxFrames, NumAudio, NumReturn, MaxSends >::set_return_processor ( uint8_t  idx, void *  ctx, FxProcess  fn  )

inline

Register an effect processor callback for a return channel. The callback is called with the accumulated send input and must process audio in-place.

Definition at line 91 of file mixer.hpp.

process()

template<uint16_t MaxFrames, uint8_t NumAudio, uint8_t NumReturn, uint8_t MaxSends = 4>

void sbl::dsp::modules::Mixer< MaxFrames, NumAudio, NumReturn, MaxSends >::process ( uint16_t  n )

inline

Process the entire mixer for one block.

Prerequisites: audio channels have been written via write_input_mono/stereo.

Steps:

1. Clear return input buffers and master bus
2. Process all audio channels (fader gain + pan)
3. Route audio channel sends to return inputs
4. For each return in order: a. Call effect processor (if registered) b. Process return channel (fader gain + pan) c. Route return-to-return sends
5. Sum all channels to master bus (mute/solo)
6. Apply master gain (fader * bus_gain * output_trim)
