DSP

DSP is an open-source C++ library for audio digital signal processing.

Usage

#include"DSP.h"intmain() {
// TODO: Do something more interesting than passing input to output// Setup engine
std::shared_ptr<dsp::Engine> engine = std::make_shared<dsp::Engine>();
unsignedint inputDevice = engine->getDefaultInputDevice();
unsignedint outputDevice = engine->getDefaultOutputDevice();
unsignedint numSamples = 512;
unsignedint sampleRate = engine->getDefaultSampleRate(inputDevice, outputDevice);
engine->setup(inputDevice, outputDevice, numSamples, sampleRate);
// Create unit
std::shared_ptr<dsp::Identity> myNode = std::make_shared<dsp::Identity>();
myNode->setNumChannels(2);
// Add unit
engine->getNodeProcessor()->getDefaultNode()->addChild(myNode);
// Connect unit
engine->getNodeProcessor()->getAudioInput() >> myNode->getInput();
myNode->getOutput() >> engine->getNodeProcessor()->getAudioOutput();
return0;
}

Future Direction

The following are possible directions for future development:

• NRT buffer system for sample player and table oscillator
• Saving state
• Loading state
• One-pole frequency response
• Pitch detection
• Pitch shifting
• Additional filters
