Abstract
Some important modifications that make the synchronized overlap-add (SOLA) algorithm of S. Roucos and A.M. Wilgus (Proc. IEEE ICASSP, p.493-6, 1985) faster while obtaining higher quality are presented. The modifications require the transmission of the synchronization factor. This results in a set of modifications of the original SOLA algorithm that cover the range from high-quality, nonreverberant to fast, good-quality reconstructions
