The convolution type of reverb can produce extremely realistic reverberation effects, and as described later, can also be useful for sound design. Some engineers prefer algorithmic reverbs because it’s possible to create “idealized” reverb spaces others prefer convolution reverb due to its “real” feel. All Audition reverbs other than the convolution reverb use algorithmic reverb technology.Įach type of reverb is useful. It’s therefore easy to create different rooms and effects with a single algorithm, whereas with convolution reverb, you would need to load different impulses for fundamentally different sounds. The trade-off for realism is a lack of flexibility.Īlgorithmic reverb creates an algorithm (mathematical model) of a space with variables that allow for changing the nature of that space. The effect then performs convolution, a mathematical operation that operates on two functions (the impulse and the audio) to create a third function that combines the impulse and the audio, thus impressing the qualities of the acoustic space onto the audio. It loads an impulse, which is an audio signal (typically in WAV file format) that embodies the characteristics of a particular, fixed acoustic space. Audition includes both.Ĭonvolution reverb is generally the more realistic sounding of the two. Two common reverb processes are convolution reverb and algorithmic reverb. Reverberation imparts an acoustic space’s characteristics (room, concert hall, garage, plate reverb) to audio.
