cljs-bach.synthesis — cljs-bach 0.3.0

add cljs

(add & synths)

Add together synths by connecting them all to the same upstream and downstream gains.

adshr cljs

(adshr attack decay sustain hold release)

An ADSR envelope that also lets you specify the hold duration.

adsr cljs

(adsr attack decay sustain release)

A four-stage envelope.

apply-to-graph cljs

(apply-to-graph f & synths)

Like apply, but for the node graphs synths produce.

audio-context cljs

(audio-context)

Construct an audio context in a way that works even if it's prefixed.

biquad-filter cljs

(biquad-filter type freq)

(biquad-filter type freq q)

Attenuate frequencies beyond the cutoff, and intensify the cutoff frequency based on the value of q.

buffer cljs

connect cljs

(connect upstream-synth downstream-synth)

Use the output of one synth as the input to another.

connect-> cljs

(connect-> & nodes)

Connect synths in series.

constant cljs

(constant x)

Make a constant value by creating noise with a fixed value.

convolver cljs

(convolver generate-bit!)

Linear convolution.

current-time cljs

(current-time context)

Return the current time as recorded by the audio context.

delay-line cljs

(delay-line seconds)

Delay the signal.

destination cljs

(destination context at duration)

The destination of the audio context i.e. the speakers.

enhance cljs

(enhance effect level)

Mix the original signal with one with the effect applied.

envelope cljs

(envelope & corners)

Build an envelope out of [segment-duration final-level] coordinates.

gain cljs

(gain level)

Multiply the signal by level.

get-mp3 cljs

(get-mp3 uri callback)

high-pass cljs

join-in-parallel cljs

(join-in-parallel upstream downstream & graphs)

join-in-series cljs

(join-in-series graph1 graph2)

low-pass cljs

noise cljs

(noise generate-bit!)

Make noise according to the supplied strategy for creating bits.

oscillator cljs

(oscillator type freq)

A periodic wave.

pass-through cljs

Pass the signal through unaltered.

percussive cljs

(percussive attack decay)

A simple envelope.

plug cljs

(plug param input context at duration)

raw-buffer cljs

(raw-buffer generate-bit! context duration)

raw-sample cljs

(raw-sample uri)

Play a sample addressed via a URI. Until fetching and decoding is complete, it will play silence.

reverb cljs

Crude reverb.

run-with cljs

(run-with synth context at duration)

Convert a synth (actually a reader fn) into a concrete subgraph by supplying context and timing.

sample cljs

sawtooth cljs

sine cljs

sink cljs

(sink node)

A graph of synthesis nodes without an output, so it can't connect to another graph.

source cljs

(source node)

A graph of synthesis nodes without an input, so another graph can't connect to it.

square cljs

stereo-panner cljs

(stereo-panner pan)

Pan the signal left (-1) or right (1).

subgraph cljs

(subgraph singleton)

(subgraph input output)

triangle cljs

white-noise cljs

Random noise.
