what is dough?

dough is a monolithic audio engine for live coding, written in a<br>single c file. it is designed after<br>superdough, the audio engine behind<br>strudel. it runs<br>both natively and in the browser.

dough is free & open source software: you can redistribute and/or<br>modify it under the terms of the<br>GNU Affero General Public License. you can find the<br>source code here.

read more about the<br>backstory here. dough draws inspiration from<br>dirt,<br>superdough,<br>kabelsalat<br>and<br>noisecraft.

caution: dough is still in development, so expect rough edges..

here's a demo with newly added sample support:

the samples are loaded using strudel.json format. a function to load<br>from the repl is coming soon..

function reference

this page introduces dough and its ideas in a linear fashion. to see<br>all available parameters, see<br>the function reference

what is dough, technically?

dough is an opinionated, fixed path, semi-modular synth that is<br>remote-controlled via messages. each message contains one or more<br>key/value pairs, which control the many parameters of the synth.

sound sources: 6 basic waveforms, 3 noise types, samples

filters: low pass, high pass, band pass

fm synthesis & pitch modulations

per-voice fx, like bitcrush, distortion and waveshaping

envelopes on many parameters

effect sends: delay, reverb, ...

to explain dough, this page uses these inputs:

you can change any of these. to hear the result, press ctrl+enter (or<br>press stop/run). to stop, you can also use ctrl+. try it!

or with multiple lines:

lines can also be commented out by putting // at the start.

envelopes

the following parameters have envelopes:

gain<br>--><br>lp*: low pass frequency

hp*: high pass frequency

bp*: band pass frequency

p*: pitch envelope

fm*: frequency modulation

for each of these, we can set the following envelope params:

a: attack time in seconds

d: decay time in seconds

s: sustain level

r: release time in seconds

e: envelope amount

for example, to get a low-pass decay, we can use the lpd param:

if we replace lpd with lpa, it turns into an attack:

we can also combine both lpa and lpd for an AD envelope:

note that the sustain value changed, based on what we set:

if we set only attack, sustain will be 1 (opens up)

if we set only decay, sustain will be 0 (closes down)

if we set attack and decay, sustain will be 0 (closes down)

of course, we can also set the sustain value explicitly:

you are strongly encouraged to play with the values to get a feel for<br>what they do!

these examples used a low pass filter envelope, but you can replace<br>the lp with any other param on the list above:

how to run dough

run it in the browser through dough.js

run the native binary and send osc

running in the browser

here's how you can run dough in the browser:

note that dough uses shared memory, so the server you're serving from<br>needs to set the following headers:

Cross-Origin-Opener-Policy: same-origin<br>Cross-Origin-Embedder-Policy: require-corp

for local development, dough provides a simple dev server that can be<br>used:

npx --yes dough-synth@latest

run it in the same directory as the above html file, then open<br>localhost:8888/.<br>the command will only work if you have<br>node.js installed.

running natively

so far, dough has no prebuilt binaries, so you need to build from<br>source. see<br>development setup<br>for more info.
