Fields

newFilter: Option<unsafe extern "C" fn() -> *mut TwoPoleFilter>

TwoPoleFilter* playdate->sound->effect->twopolefilter->newFilter(void)

Creates a new two pole filter effect.

freeFilter: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter)>

void playdate->sound->effect->twopolefilter->freeFilter(TwoPoleFilter* filter)

Frees the given filter.

setType: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter, type_: TwoPoleFilterType)>

void playdate->sound->effect->twopolefilter->setType(TwoPoleFilter* filter, TwoPoleFilterType type)

TwoPoleFilterType

typedef enum
{
	kFilterTypeLowPass,
	kFilterTypeHighPass,
	kFilterTypeBandPass,
	kFilterTypeNotch,
	kFilterTypePEQ,
	kFilterTypeLowShelf,
	kFilterTypeHighShelf
} TwoPoleFilterType;

Sets the type of the filter.

setFrequency: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter, frequency: c_float)>

void playdate->sound->effect->twopolefilter->setFrequency(TwoPoleFilter* filter, float frequency)

Sets the center/corner frequency of the filter. Value is in Hz.

setFrequencyModulator: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter, signal: *mut PDSynthSignalValue)>

void playdate->sound->effect->twopolefilter->setFrequencyModulator(TwoPoleFilter* filter, PDSynthSignalValue* signal)

Sets a signal to modulate the effect’s frequency. The signal is scaled so that a value of 1.0 corresponds to half the sample rate. Set to NULL to clear the modulator.

getFrequencyModulator: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter) -> *mut PDSynthSignalValue>

PDSynthSignalValue* playdate->sound->effect->twopolefilter->getFrequencyModulator(TwoPoleFilter* filter)

Returns the filter’s current frequency modulator.

setGain: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter, gain: c_float)>

void playdate->sound->effect->twopolefilter->setGain(TwoPoleFilter* filter, float gain)

Sets the filter gain.

setResonance: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter, resonance: c_float)>

void playdate->sound->effect->twopolefilter->setResonance(TwoPoleFilter* filter, float resonance)

Sets the filter resonance.

setResonanceModulator: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter, signal: *mut PDSynthSignalValue)>

void playdate->sound->effect->twopolefilter->setResonanceModulator(TwoPoleFilter* filter, PDSynthSignalValue* signal)

Sets a signal to modulate the filter resonance. Set to NULL to clear the modulator.

getResonanceModulator: Option<unsafe extern "C" fn(filter: *mut TwoPoleFilter) -> *mut PDSynthSignalValue>

PDSynthSignalValue* playdate->sound->effect->twopolefilter->getResonanceModulator(TwoPoleFilter* filter)

Returns the filter’s current resonance modulator.

Trait Implementations
