Convolution / Sampling reverb

In by phoenixgreen

  • Convolution reverb became a reality with increased processing power
  • It appeared in studios in the 2000’s
  • Sony pioneered this type of reverb
  • Convolution reverb takes a sample of the reverb of a space called an impulse response. This is created by emitting an excitation/stimulus into the room. Such signals include a sine sweep/balloon pop/gun shoot. Frequently, the excitation signal must later be de-convolved from the impulse response or cut from the start of the impulse response.
  • It is then convolved with the dry signal to produce the reverb.
  • It allows a sound to be placed in a specific venue without having to actually visit it, or to recreate specific hardware units.
