Struct SineSource 

pub struct SineSource { /* private fields */ }

A deterministic test tone: a sine at freq_hz and peak amplitude, the same on every channel, with timestamps that advance by block duration.

Implementations

impl SineSource

pub fn new(format: PcmFormat, freq_hz: f32, amplitude: i16) -> Result<Self>

A tone in format, which must be SampleFormat::I16.

pub fn reset(&mut self)

Restart the tone at phase zero and time zero.

Trait Implementations

impl AudioSource for SineSource

fn format(&self) -> PcmFormat

Rate, channels and encoding of every block this source produces.

fn read<'b>(&mut self, out: &'b mut [u8]) -> Result<PcmBlock<'b>>

Fill out completely (it must be a whole number of frames) and return the block over it, stamped with the capture time of its first frame.

impl Clone for SineSource

fn clone(&self) -> SineSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SineSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
