Module sampara::signal

Structs

AddAmp	Adds a constant Sample to each channel in each Frame from a Signal.
AddFrame	Adds a constant Frame to each Frame from a Signal.
AddSignal	Adds together pairs of Frames from two Signals in lockstep and yields their sum.
Constant	A Signal that yields a given Frame repeatedly forever.
Delay	Delays a Signal a given number of Frames by yielding Frame::EQUILIBRIUM that many times before yielding from the contained Signal.
Empty	A Signal that yields zero Frames, mainly used in combination with other Signals.
Equilibrium	A Signal that yields Frame::EQUILIBRIUM forever.
Fixed
FromFn	A Signal that yields Frames by calling a closure for each iteration. This closure should return Option<Frame>.
FromFrames	A Signal that is powered by an underlying Iterator that yields Frames.
FromSamples	A Signal that is powered by an underlying Iterator that yields Samples.
Inspect	Creates a new Signal that calls a function with each Frame, and then yields the Frame.
IntoIter	Converts a Signal into a Iterator.
Map	Maps a function to each Frame from a Signal and yields a new Frame.
MulAmp	Multiplies a constant Sample to each channel in each Frame from a Signal.
MulFrame	Multiplies a constant Frame to each Frame from a Signal.
MulSignal	Multiplies together pairs of Frames from two Signals in lockstep and yields their product.
Phase	A Signal that wraps a Delta and accumulates it in an automated way, wrapping it to the interval [0.0, 1.0) as needed.
Saw	A saw wave Signal generator.
Sine	A sine wave Signal generator.
Square	A square wave Signal generator.
Take	Creates a new Signal that yields the first N Frames of a Signal, and then stops.
Variable
ZipMap	Maps a function to each pair of Frames from two Signals in lockstep and yields a new Frame.

Traits

Delta	Types that can produce a phase step size, usually based on a target frequency divided by a sampling frequency (sample rate).
Signal	Types that yield a sequence of Frames, representing an audio signal.

Functions

constant	Creates a new Signal where each Frame is copied from a given constant Frame.
empty	Creates an empty Signal that yields no Frames.
equilibrium	Creates a new Signal that always yields Frame::EQUILIBRIUM.
from_fn	Creates a new Signal where each Frame is yielded by calling a given closure that produces a Option<Frame> for each iteration.
from_frames	Creates a new Signal by wrapping an iterable that yields Frames.
from_samples	Creates a new Signal by wrapping an iterable that yields [Samples]s. These Samples are assumed to be interleaved, and in channel order. The resulting Signal will read these Samples into Frames of the desired size, and yield them. Any trailing Samples that do not fully complete a Frame will be discarded.
phase_hz	Creates a Phase with a constant Frame of frequencies.
phase_hzs	Creates a Phase with Frames of deltas over time, as yielded by a Signal.
phase_step	Creates a Phase with a constant Frame of deltas.
phase_steps	Creates a Phase with Frames of deltas over time, as yielded by a Signal.
