Stereo and multi-channel audio coding for mobile communication applications is challenging due to bitrate, latency and computational complexity constraints. To address these constraints, a novel MDCT-based stereo coding scheme is introduced. A key feature of this scheme is the broadband inter-channe…
This paper describes new time domain techniques for concealing packet loss in the new 3GPP Enhanced Voice Services codec. Enhancements to the existing ACELP concealment methods include guided, improved pitch prediction, increased flexibility and accuracy of pulse resynchronization. Furthermore, the…
Speech coders operating in time domain can be extended with a frequency domain mode to improve encoding of music, even though this is challenging at low delay. In such a scenario, the short analysis window limits the benefit of the transform coder, while a delayless switch between the two coders con…
