Progress on parametric coding for high quality audioErik SchuijersWerner OomenAlbertus Den BrinkerJeroen Breebaart
Advances in Parametric Coding for High-Quality Audio In the course of the 'MPEG-4 Extension 2' standardisation process, a parametric coding scheme is under development. This coding scheme is based on the notion that any audio signal can be dissected into three objects: transient, sinusoids... ...

The invention in addition relates to an audio decoder, methods of encoding and decoding as well as an encoded signal and devices comprising an encoder and a decoder. Audio coding according to the invention provides a high sound quality for transient sounds echo effects while it is still bit ...
Audio and Acoustics Graphics and multimedia Parametric Wave Field Coding for Precomputed Sound Propagation The acoustic wave field in a complex scene is a chaotic 7D function of time and the positions of source and listener, making it difficult to compress and interpolate. This hampers...
For Internet audio streaming purposes, a good trade-off between bit rate reduction and audio quality is achieved by using parametric audio coding. A scalable parametric coder has been optimized for this requirement, avoiding differential encoding and using a layered scheme for changing straightforwardly...
This paper presentes a new robust pitch estimation algorithm for parametric speech coding with transparent quality at very low bit rate. 为了实现甚低码率下的透明语音质量参数语音编码,该文提出了一种新的鲁棒的基音周期估计算法。3) parametric audio coding 参数音频编码 1. With a brief review of cu...
downmix signal, wherein the K groups are predefined, and wherein the mixing coefficients are determined such that a single partition of the M-channel audio signal into the K groups of channels, approximated by the channels of the output signal, is maintained for said at least two coding ...
Parametric spatial coding of multichannel content has acquired widespread use in today’s audio codecs to enable efficient operation in the medium bitrate range. However, applause signals are still challenging to code with good perceptual quality using these techniques. To obtain a sufficiently low ...
Video coding scalability has an effect on bitrate requirement and peak signal-to-noise ratio (PSNR). However, the spatial information (SI) and temporal information (TI), that are inherent properties of the video, need to be maintained for the full-high-definition videos while performing scalably...
