Download A Fast Mellin Transform with Applications in DAFx Many digital audio effects rely on transformations performed in the Fourier-transformed (frequency) domain. However, other transforms and domains exist and could be exploited. We propose to use the Mellin transform for a class of sound transformations. We present a fast implementation of the Mellin transform (more precisely a Fast Scale Transform), and we provide some examples on how it could be used in digital audio effects.
Download The Mellin Pizzicator In this paper an application of the Mellin transform to the digital audio effects will be presented. Namely, low-pass and band-pass like filtering in the Mellin domain will be described and used for obtaining some kind of pizzicato effect on audio samples (musical instruments, but not only). The pluck and damp effects will be obtained using filtering in Mellin domain only. The algorithm used for implementing the Mellin (scale) transform has been presented in DAFx’04 [1].
