ABSTRACT
Convolution Reverb When an acoustic sound is created, its characteristics are shaped by its immediate environment . This is due to sound waves bouncing off and around various obstacles . These obstacles can be made of different materials that affect the sound in different ways . The result of sound emanating from a small room has different characteristics than sound emanating from a large room . Because the human ear can hear these differences, when this information is transmitted to the brain, we perceive these characteristics as room ambience . Modern advancements in digital audio technology allow us to record the ambience of any real-world environment and apply it to any digital audio signal directly . These recorded ambiences are stored as a special file called an impulse response . An impulse response file is made by recording a single sound burst in an environment, which could be white noise, a sine wave sweep, or even a balloon pop . This recording is then run through a special digital algorithm to create a single file called an impulse response . This impulse response file is combined or convolved with another input
source to give the targeted sound the spacial characteristics of the room that the impulse is modeled from .
