What is C++ sound synthesis?

Can you explain what C++ sound synthesis is?

C++ sound synthesis involves using C++ programming to create and manipulate sound. It's often used in audio applications.

What are some common techniques used in sound synthesis with C++?

Common techniques include additive synthesis, subtractive synthesis, and granular synthesis, each with unique sound creation methods.

Can you give me an example of a simple C++ sound synthesis program?

Sure! A basic example would be using the RtAudio library to generate a sine wave. Would you like to see the code?

Yes, please share the code for generating a sine wave.

Here's a simple example:

#include <RtAudio.h>
#include <cmath>

int sineWave(void *outputBuffer, void *inputBuffer, unsigned int nBufferFrames,
            double streamTime, RtAudioStreamStatus status, void *data) {
    double *buffer = (double *)outputBuffer;
    double frequency = 440.0; // A4 note
    for (unsigned int i = 0; i < nBufferFrames; i++) {
        buffer[i] = 0.5 * sin(2 * M_PI * frequency * streamTime);
        streamTime += 1.0 / 44100; // Assuming 44100 Hz sample rate
    }
    return 0;
}

int main() {
    RtAudio audio;
    audio.openStream(NULL, NULL, RTAUDIO_FLOAT64, 44100, &nBufferFrames, &sineWave);
    audio.startStream();
    // Keep the stream open for a while
    std::this_thread::sleep_for(std::chrono::seconds(5));
    audio.stopStream();
    audio.closeStream();
    return 0;
}

What libraries do I need to use for sound synthesis in C++?

You can use libraries like RtAudio for audio I/O, JUCE for audio applications, and PortAudio for cross-platform audio.
