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 we feed it.…
These techniques can be practiced with the free Get in the Mix sessions, currently available for Pro Tools and Logic Pro.
