IEEE International Conference on Consumer Electronics (ICCE)
作者: J. Chen H.-M. Tai Department of Electrical Engineering University of Tulsa Tulsa OK USA
This paper presents the implementation of an MPEG-2 advanced audio coding (AAC) coder on a fixed-point DSP. AAC is a powerful coding algorithm and offers high-quality multi-channel surround audio. We also discuss the ... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: A. Jbira A. Kondoz Centre for Communication Systems Research University of Surrey Guildford Surrey UK
In this paper we propose a multiple frequency harmonics model for analysis and synthesis of audio signals. The novelty of this model is that a composite sound can be represented by a few number (two or three) of frequ... 详细信息

2007 International Symposium on Communications and Information Technologies (ISCIT 2007), vol.2
作者: Xuejie Song Soura Dasgupta Department of Electrical and Computer Engineering University of Iowa Iowa USA
We consider optimum Transform coding. The objective is to minimize the distortion variance by selecting an optimum transform matrix and bit allocation among the sub-band signals. Under an asymptotic expression for the... 详细信息

IEEE Global Conference on Signal and Information Processing
作者: Vaclav Eksler Milan Jelinek Wolfgang Jaegers University of Sherbrooke VoiceAge Corporation Montreal QC Canada Fraunhofer IIS Erlangen Germany
Speech and audio codecs are usually designed such that they encode all the frequency bands of the input signal spectrum. If the higher bands do not contain any perceptually meaningful content, these codecs often do no... 详细信息
