FX Colletion Library

Summary

The fx-collection library combines basic classes from dsp-tool-box to audio effects. The trance gate effect for example uses three modulation phases and a one pole filter from the dsp-tool-box.

Effects

Currently the following effects are avaiable:

Trance Gate

Using the effects

All effect classes in this library contain a context and static methods in order to modify the context. Like this the data and the algorithm are separated and allow a usage in a multithreaded environment.

Setting parameters of the context

For the trance gate for instance, use the trance_gate::create method in order to get a valid context. Afterwards use the static methods like set_mix to modify the context.

auto tg_context = ha::fx_collection::trance_gate::create();
ha::fx_collection::trance_gate::set_mix(tg_context, 1.);

Processing an effect

In order to process the trance gate for instance, use the process method. This method takes an input audio_frame and an output audio_frame. The audio_frame struct contains an alinged buffer of four channels.

auto tg_context = ha::fx_collection::trance_gate::create();
ha::fx_collection::trance_gate::set_mix(tg_context, 1.);

ha::fx_collection::audio_frame input; // Insert your sample here
ha::fx_collection::audio_frame output;

ha::fx_collection::trance_gate::process(tg_context, input, output);

// Use the output for further processing
