Struct spectrusty_core::audio::BlepStereo

pub struct BlepStereo<B: Blep> {
    pub mono_filter: B::SampleDelta,
    pub blep: B,
}

A wrapper Blep implementation that redirects extra channels to a stereo Blep as a monophonic channel.

Requires a downstream Blep implementation that provides at least 2 audio channels.

BlepStereo channel      Blep impl channel
    0 -----------------------> 0
    1 -----------------------> 1
 >= 2 ---- * mono_filter ----> 0
                         \---> 1

Fields

mono_filter: B::SampleDelta

A monophonic filter value in the range [0.0, 1.0] (floats) or [0, int::max_value()] (integers).

blep: B

A downstream Blep implementation.

Implementations

impl<B: Blep> BlepStereo<B>

pub fn build(mono_filter: B::SampleDelta) -> impl FnOnce(B) -> Self

pub fn new(mono_filter: B::SampleDelta, blep: B) -> Self

Trait Implementations

impl<B> Blep for BlepStereo<B> where
    B: Blep,
    B::SampleDelta: MulNorm + SampleDelta, 

type SampleDelta = B::SampleDelta

A type for sample ∆ amplitudes (pulse height).

pub fn ensure_frame_time(
    &mut self,
    sample_rate: u32,
    ts_rate: f64,
    frame_ts: FTs,
    margin_ts: FTs
)

This method allows the Blep implementation to reserve enough memory for the audio frame with an additional margin and to set up a sample time rate and other internals.

pub fn end_frame(&mut self, timestamp: FTs) -> usize

Finalizes audio frame.

pub fn add_step(
    &mut self,
    channel: usize,
    timestamp: FTs,
    delta: B::SampleDelta
)

This method is being used to add square-wave pulse steps within a boundary of a single frame.

impl<B: Blep> Deref for BlepStereo<B>

type Target = B

The resulting type after dereferencing.

pub fn deref(&self) -> &B

Dereferences the value.

impl<B: Blep> DerefMut for BlepStereo<B>

pub fn deref_mut(&mut self) -> &mut B

Mutably dereferences the value.
