- reverberator: Add reverberation to audio signal
- audiopluginexample.Chorus: Adds an audio chorus effect. The chorus effect is implemented by modulating two delay lines.
- audiopluginexample.Echo: Implements an audio echo effect using two delay lines. The plugin user tunes the delay taps in seconds, the gain of the delay taps, and the output dry/wet mix.
- audiopluginexample.Flanger: Implements an audio flanging effect using a modulated delay line. The plugin user tunes the delay tap in seconds, the amplitude and frequency of the delay line modulation, and the output dry/wet mix.
- audiopluginexample.Strobe: Implements an audio strobing effect. Tunable parameters of the plugin include the strobe period, the strobe fill, a relative level threshold for implementing the effect, and the ability to synchronize the strobe period with the audio signal dynamics.

function impulseResponse = createDelayImpulseResponse(app, sampleRate, delayInSeconds, amplitude)
delaySamples = round(delayInSeconds * sampleRate); % Convert delay to samples
impulseResponse = zeros(delaySamples + 1, 1); % Create a zero vector
impulseResponse(1) = amplitude; % Original signal
impulseResponse (delaySamples+1) = 1; %Signal Delayed
end
function impulseResponse = createEchoImpulseResponse(app, sampleRate, delayInSeconds, decayFactor)
delaySamples = round(delayInSeconds * sampleRate);
impulseResponse = zeros(delaySamples, 1);
impulseResponse(1) = 1; % Original signal
impulseResponse(end) = decayFactor; % Echo signal with decay
end
function impulseResponse = createReverbImpulseResponse(app, sampleRate, duration, decayFactor)
delaySamples = round(sampleRate * duration);
impulseResponse = zeros(delaySamples, 1);
% Simulate reverb with several delays
for i = 1:4
impulseResponse(i * round(sampleRate * 0.1)) = decayFactor^(i-1); % Adjust delay and decay
end
end
I use this code then
app.convolvedAudio = conv(app.audioData, impulseResponse)
i get the convolved audio with this.
I am a beginner are these right? Can you suggest me more audio effects?
