Implementations§

Source §

impl SignalGenerator

Source

pub fn sine( freq_hz: f32, amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Pure sine wave.

Source

pub fn square( freq_hz: f32, amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Square wave via Fourier synthesis (up to harmonics odd harmonics).

Source

pub fn triangle( freq_hz: f32, amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Triangle wave.

Source

pub fn sawtooth( freq_hz: f32, amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Sawtooth wave.

Source

pub fn noise( amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

White noise (uniform distribution in [-amplitude, amplitude]).

Source

pub fn chirp( f0_hz: f32, f1_hz: f32, amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Linear chirp sweeping from f0_hz to f1_hz over duration_secs.

Source

pub fn pulse( amplitude: f32, pulse_width_secs: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Rectangular pulse: high for pulse_width_secs then zero.

Source

pub fn impulse( amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Unit impulse (Dirac delta approximation): 1.0 at sample 0, 0.0 elsewhere.

Source

pub fn gabor( freq_hz: f32, sigma: f32, center_secs: f32, amplitude: f32, duration_secs: f32, sample_rate: f32, ) -> Signal<f32>

Gaussian-modulated sine (Gabor atom) for analysis.

Blanket Implementations§

Source §

impl<T> Any for T
where T: 'static + ?Sized,

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<T> BorrowMut<T> for T
where T: ?Sized,

Source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
