Spectral Envelope Correction for Real-Time Transposition: Proposal of a “Floating-Formant” Method

Author

Richard Dudas

Abstract

A common problem of sound transposition is that the spectra of the resulting transpositions are often very unconvincing to the human ear in terms of their relation to the original sound. This paper examines the problem, takes a look at some existing solutions and their drawbacks and proposes a generalized method to correct this “unconvincingness” which can be used on a variety of instrumental and non-instrumental sounds.
