Mandatory Intro

Well, These are just bunch of Impulse responses which you can play with.


Use MATLAB®/Scilab®/Python(numpy) to convolve with your favorite sound/music. They can also be used to do few other things as well, but its beyond the scope of this document. You can also use Adobe® Audition® if you prefer GUI and code-free approach.
