Optimized multiple wavetable interpolation
Jonathan Mohr, Xiaobo Li · International Conference on Signal Processing · 2005
One effective approach to music analysis/synthesis is multiple wavetable interpolation, which matches an audio signal at selected breakpoints by determining weightings for several wavetables; the sound is resynthesized using multiple wavetable additive synthesis by interpolating between the weightings for each wavetable at consecutive breakpoints. This article presents a new breakpoint-matching algorithm which uses the single-source acyclic weighted shortest path algorithm to choose breakpoint matches in a globally optimal way.
