Perceptual coding-based informed source separation

Abstract

Serap Kırbız (MEF Author)##nofulltext##Informed Source Separation (ISS) techniques enable manipulation of the source signals that compose an audio mixture, based on a coder-decoder configuration. Provided the source signals are known at the encoder, a low-bitrate side-information is sent to the decoder and permits to achieve efficient source separation. Recent research has focused on a Coding-based ISS framework, which has an advantage to encode the desired audio objects, while exploiting their mixture in an information-theoretic framework. Here, we show how the perceptual quality of the separated sources can be improved by inserting perceptual source coding techniques in this framework, achieving a continuum of optimal bitrate-perceptual distortion trade-offs.WOS:0003934202001932-s2.0-84911919618Conference Proceedings Citation Index- ScienceProceedings PaperEylülYÖK - 2014-1
