Method and system for artificial reverberation employing reverberation impulse response synthesis

Abstract

The present embodiments relate to audio effect processing, and more particularly to a method for creating reverberation impulse responses from prerecorded or live source materials forms the basis of a family of reverberation effects. In one embodiment, segments of audio are selected and processed to form an evolving sequence of reverberation impulse responses that are applied to the original source material—that is, an audio stream reverberating itself. In another embodiment, impulse responses derived from one audio track are applied to another audio track. In a further embodiment, reverberation impulse responses are formed by summing randomly selected segments of the source audio, and imposing reverberation characteristics, including reverberation time, wet equalization, wet-dry mix, and predelay. By controlling the number and timing of the selected source audio segments, the method produces a collection of impulse responses that represent a trajectory through the source material. In so doing, the evolving impulse responses will have the character of room reverberation while also expressing the changing timbre and dynamics of the source audio.
