Details

Engine id: org.sournd.utility.breadth
Category: Utility
Type: Width, mono
Licence: Free, closed library (use it in any plugin)
Version: 1.0.0
Parameters: 2
Latency: none
Tail: 0.05 s
Sidechain input: no
Channels: mono or stereo

Parameters

The id is the C ABI parameter id and the JUCE parameter id (as a decimal string).

Id	Key	Name	Min	Max	Default	Unit	Taper
0	`width_pct`	Width	0	200	100	%	linear
1	`mono_below_hz`	Mono below	0	500	0	Hz	linear

How it is made

Original sOURnd utility blending general techniques: mid/side encoding, a scaled side channel and a two-pole side high-pass for a mono low end.

CMake

C++ (JUCE)

cpp

#include <sournd_engine/sournd_engine.h>

sournd::SourndEngine engine { "org.sournd.utility.breadth" };
juce::AudioProcessorValueTreeState parameters { *this, nullptr, "Parameters",
    sournd::SourndEngineParameters::createLayout (engine) };
sournd::SourndEngineParameters bridge { engine, parameters };

// prepareToPlay
engine.prepare ({ sampleRate, (juce::uint32) maximumBlock, 2 });
bridge.prepare (sampleRate);
setLatencySamples ((int) engine.latency());

// processBlock
bridge.apply ((uint32_t) buffer.getNumSamples());
juce::dsp::AudioBlock<float> block { buffer };
engine.process (juce::dsp::ProcessContextReplacing<float> { block });

// get/setStateInformation: hold getCallbackLock() around saveState / loadState,
// so state work never overlaps processBlock (full example: /docs/juce/)

Plain C

sournd_engine *e = NULL;
if (sournd_engine_create("org.sournd.utility.breadth", &e) == SOURND_OK) {
    sournd_engine_prepare(e, 48000.0, 512);
    sournd_engine_set_param(e, 0, 100); /* Width */
    sournd_engine_process(e, in, out, 2, frames);
    sournd_engine_destroy(e);
