Fields

newDelayLine: Option<unsafe extern "C" fn(length: c_int, stereo: c_int) -> *mut DelayLine>

DelayLine* playdate->sound->effect->delayline->newDelayLine(int length, int stereo)

Creates a new delay line effect. The length parameter is given in samples.

freeDelayLine: Option<unsafe extern "C" fn(filter: *mut DelayLine)>

void playdate->sound->effect->delayline->freeDelayLine(DelayLine* delay)

Frees the delay line.

setLength: Option<unsafe extern "C" fn(d: *mut DelayLine, frames: c_int)>

void playdate->sound->effect->delayline->setLength(DelayLine* d, int frames)

Changes the length of the delay line, clearing its contents.

setFeedback: Option<unsafe extern "C" fn(d: *mut DelayLine, fb: c_float)>

void playdate->sound->effect->delayline->setFeedback(DelayLine* d, float fb)

Sets the feedback level of the delay line.

addTap: Option<unsafe extern "C" fn(d: *mut DelayLine, delay: c_int) -> *mut DelayLineTap>

DelayLineTap* playdate->sound->effect->delayline->addTap(DelayLine* d, int delay)

Returns a new tap on the delay line, at the given position. delay must be less than or equal to the length of the delay line.

freeTap: Option<unsafe extern "C" fn(tap: *mut DelayLineTap)>

void playdate->sound->effect->delayline->freeTap(DelayLineTap* tap)

Frees a tap previously created with playdate→sound→delayline→addTap(), first removing it from the sound engine if needed.

setTapDelay: Option<unsafe extern "C" fn(t: *mut DelayLineTap, frames: c_int)>

void playdate->sound->effect->delayline->setTapDelay(DelayLineTap* tap, int frames)

Sets the position of the tap on the delay line, up to the delay line’s length.

setTapDelayModulator: Option<unsafe extern "C" fn(t: *mut DelayLineTap, mod_: *mut PDSynthSignalValue)>

void playdate->sound->effect->delayline->setTapDelayModulator(DelayLineTap* tap, PDSynthSignalValue* mod)

Sets a signal to modulate the tap delay. If the signal is continuous (e.g. an envelope or a triangle LFO, but not a square LFO) playback is sped up or slowed down to compress or expand time. Set to NULL to clear the modulator.

getTapDelayModulator: Option<unsafe extern "C" fn(t: *mut DelayLineTap) -> *mut PDSynthSignalValue>

PDSynthSignalValue* playdate->sound->effect->delayline->getTapDelayModulator(DelayLineTap* tap)

Returns the current delay modulator.

setTapChannelsFlipped: Option<unsafe extern "C" fn(t: *mut DelayLineTap, flip: c_int)>

void playdate->sound->effect->delayline->setTapChannelsFlipped(DelayLineTap* tap, int flip)

If the delay line is stereo and flip is set, the tap outputs the delay line’s left channel to its right output and vice versa.

Trait Implementations

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
