MATLAB: How to add an echo to an audio file and control the SER (signal to echo ratio) with MATLAB audiosignal processing I can add echo to the audio through convolution. But I don't know how to adjust SER. What should I do? Best Answer Hi Seoungyook, You can adjust the scaling factor (Gain/Attenuation of the reflected signal) of the delayed signal to tune your Signal-to-Echo Ratio.

If there is a speaker or headphones jack on the system, the analog signal can be pulled off of that. MATLAB: Create an echo effect The loop just goes through each time point in the signal adding in a fraction of the signal from an earlier time point.Attach your code as an m-file with the paper clip icon if you need more help so people can run it.
