   Sammanfattning : thesis is about audio coding and improving flexibility thereof. Audio coding is used to reduce the bit rate needed to represent audio signals in digital format. When the available bit rate is low, parametric coding methods that use models to describe perceptually-important features of audio signals have shown their efficiency. LÄS MER

3. 2. From Modeling to Perception - Topics in Speech Coding

   Författare :Jan Skoglund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Transmission and storage of speech require an efficient representation of the speech signal. The conversion of the acoustic speech waveform into a suitable digital representation is called speech coding. This thesis consists of six papers contributing to different research areas in speech coding. LÄS MER
