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.
