Predicting the Fluctuation Strength of the Output of a Spatial Chorus Effects Processor
The experimental study reported in this paper was motivated by an exploration of a set of related audio effects comprising what has been called ‚Äúspatial chorus.‚Äù In contrast to a single-output, delay-modulation-based effects processor that produces a limited range of results, complex spatial imagery is produced when parallel processing channels are subjected to incoherent delay modulation. In order to develop a more adequate user interface for control of such ‚Äúspatial chorus‚Äù effects processing, a systematic investigation of the relationship between algorithmic parameters and perceptual attributes was undertaken. The starting point for this investigation was to perceptually scale the amount of modulation present in a set of characteristic stimuli in terms of the auditory attribute that Fastl and Zwicker called ‚Äúfluctuation strength.‚Äù
