How can I process audio files using C++?

You can use libraries like PortAudio or JUCE for audio processing in C++. What specific tasks do you want to accomplish?

I want to apply effects like reverb and echo.

For effects like reverb and echo, JUCE is a great choice. It has built-in classes for audio effects. Would you like a code example?

Yes, please provide a simple example.

Here's a basic example using JUCE to apply reverb:

#include <JuceHeader.h>

class ReverbAudioProcessor : public AudioProcessor {
    Reverb reverb;
    Reverb::Parameters reverbParams;

public:
    ReverbAudioProcessor() {
        reverbParams.roomSize = 0.5f;
        reverbParams.damping = 0.5f;
        reverb.setParameters(reverbParams);
    }

    void processBlock(AudioBuffer<float>& buffer, MidiBuffer& midiMessages) override {
        for (int channel = 0; channel < buffer.getNumChannels(); ++channel) {
            reverb.processMono(buffer.getWritePointer(channel), buffer.getNumSamples());
        }
    }
};

This code sets up a simple reverb effect.
