Perceptually Motivated Sub-band Decomposition for FDLP Audio Coding [PDF]
, 2008 This paper describes employment of non-uniform QMF decomposition to increase the efficiency of a generic wide-band audio coding system based on Frequency Domain Linear Prediction (FDLP). The base line FDLP codec, operating at high bit-rates (~136 kbps), exploits a uniform QMF decomposition into 64 sub-bands followed by sub-band processing based on FDLP.

Perceptual coding of digital audio [PDF]
Proceedings of the IEEE, 2000 During the last decade, CD-quality digital audio has essentially replaced analog audio. Emerging digital audio applications for network, wireless, and multimedia computing systems face a series of constraints such as reduced channel bandwidth, limited storage capacity, and low cost.

A Multimedia Application: Spatial Perceptual Entropy of Multichannel Audio Signals
EURASIP Journal on Wireless Communications and Networking, 2010 Usually multimedia data have to be compressed before transmitting, and higher compression rate, or equivalently lower bitrate, relieves the load of communication channels but impacts negatively the quality.

A novel steganography approach for audio files [PDF]
, 2020 We present a novel robust and secure steganography technique to hide images into audio files aiming at increasing the carrier medium capacity. The audio files are in the standard WAV format, which is based on the LSB algorithm while images are ...

Reducing Audible Spectral Discontinuities [PDF]
, 2001 In this paper, a common problem in diphone synthesis is discussed, viz., the occurrence of audible discontinuities at diphone boundaries. Informal observations show that spectral mismatch is most likely the cause of this phenomenon.We first set out to ...

Multiresolution Source/Filter Model for Low Bitrate Coding of Spot Microphone Signals
EURASIP Journal on Audio, Speech, and Music Processing, 2008 A multiresolution source/filter model for coding of audio source signals (spot recordings) is proposed. Spot recordings are a subset of the multimicrophone recordings of a music performance, before the mixing process is applied for producing the final ...
