A Hybrid Approach to the Variable-Speed Replay of Digital Audio

Authors: Gaskell, Philip S.

AES Convention 77 · Paper 2202 · March 1985

Abstract

A method is described for replaying digital audio from any recording medium at speeds varying continuously from standstill to many times nominal speed. A hybrid approach is adopted which combines switched interpolation digital filters with a fixed reconstruction filter. Its performance is suitable for high quality applications and only requires relatively modest signal processing hardware.
