Mandatory Intro

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

How?

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.

Whats an Impulse Response?

Impulse Responses

Here is a table of collected impulse responses. Please note that some are multi-channel and some are really short. these are intended for reverberation effects and are usually 1-5 seconds long at 44100-48000 Hz. Sample rate & other metadata is not listed in the table but will be in the future. Please refer to File suffix/prefix section which explains the licenses and Terms of use.
