SIR (Super Impulse Response)

Super Impulse Response!

Allows you to make super high quality reverb and model a room or space's reverberation fingerprint exactly.

PLEASE NOTE: While the sound quality is excellent, this VST is not recommended for beginners.


This is a free effect that models acoustic spaces!  For example, you can make it sound like you are in a famous church or amphitheater by going to the location, play a bit of noise, record the sound and then apply that to other recordings.  Luckily, some people have posted free acoustic spaces so you don't have to record them on location!
