Attaq

Shape the strike, shape the glow.

Transient shaper: boost or soften the attack of each hit and lift or tuck its sustain, independent of level, with a speed control for tight or loose envelopes and a clip-safe output.

Details

Engine id: org.sournd.dynamics.attaq
Category: Dynamics
Type: Transient
Licence: Free, closed library (use it in any plugin)
Version: 1.0.0
Parameters: 6
Latency: none
Tail: 0.5 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	`attack_pct`	Attack	-100	100	0	%	linear
1	`sustain_pct`	Sustain	-100	100	0	%	linear
2	`speed_pct`	Speed	0	100	50	%	linear
3	`output_db`	Output	-18	18	0	dB	linear
4	`clip`	Clip-safe output	0	1	1	-	linear
5	`mix`	Mix	0	100	100	%	linear

How it is made

Original sOURnd design blending general techniques: stereo-linked peak sensing, three envelope followers whose log-domain differences separate attack from sustain, a smoothed gain in dB, and a soft output ceiling.

C++ (JUCE)

cpp

#include <sournd_engine/sournd_engine.h>

sournd::SourndEngine engine { "org.sournd.dynamics.attaq" };
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.dynamics.attaq", &e) == SOURND_OK) {
    sournd_engine_prepare(e, 48000.0, 512);
    sournd_engine_set_param(e, 0, 0); /* Attack */
    sournd_engine_process(e, in, out, 2, frames);
    sournd_engine_destroy(e);
