Hi Adnan,

You can accomplish this with the reverberator object in Audio Toolbox:

https://www.mathworks.com/help/audio/ref/reverberator-system-object.html

Here is an example where you read a signal from a file and add reverb to it:

[audioIn, fs] = audioread('speech_dft.mp3');
r = reverberator('SampleRate',fs);
audioOut = r(audioIn);
sound(audioOut,fs)

See the ref page for information about reverberation parameters you can set.

@jibrahim Can someone tell me how can I create a 0.1sec delay decaying reverb in an audio file using this command? I want to use the command in order to create a reverb accroding to the following impulse response in the photo.

willl be of great help.

Below I have attached a photo of the reverb I am trying to add to the audio using the reverberator command.

Thank you everyone!
