Using convolution correctly

Convolution brings a major capability to our studio. Any track we record using typical close miking techniques can be sonically transported to sound as if it were recorded in any space in the world. All you need is the impulse response of that space. We use convolution to put our pianos in the finest concert halls in Europe, our drums in the best recording studios in Los Angeles, and our vocals in the most thunderously awesome caves in Africa. But convolution does have limits, so we take a look under the hood in this movie and the next, so that we're better informed users of the technology.

Recall the convolution is done by sending an impulse into the room, a simple single instantaneous spike and recording the resulting pattern of spikes that follows. This pattern of spikes defines the sound of the room. It's called the impulse response, as it is the acoustic response of the room to an impulse signal. The process of convolution applies the room's response to any other signal...
