Inv. frequency response to even rooms sound caracteristics

Post by Revolverman »

The frequency responce in the room I am recording in is far away from even . Instead of fixing the acoustics physically I thought that it may be fixed digitally in the computer.

The idea is to record the rooms impulse-response then invert it and use it in a convolution reverb.

Is this a good or bad idea? And how should I do it in practice?

That's a clever idea, but it won't work because whatever "correction" you apply will be valid in only one very small place in the room. You can't even fix the sound for both of your ears at the same time. :) Another problem is you can't counter deep nulls, and all small rooms have a half dozen or more of those.

This is why bass traps and other acoustic treatment are always the first line of attack. Traps improve both peaks and nulls, and reduce ringing, and the improvement is everywhere in the room.
