The paper presents a simple, yet very effective tracking technique for time-varying sinusoidal partials within sinusoidal and hybrid models of speech and audio. The issues of several existing tracking techniques are discussed in the paper. We extend the classic tracking algorithm of McAulay and Quatieri by the inclusion of frequency and amplitude skew(More)
A generalized scheme for mapping stereo audio channels onto coding channels is considered in the paper. An improved joint stereo transform−based perceptual audio coder is proposed that employs this scheme instead of MS coding. The discussed frequency−dependent matrixing scheme uses a free rotation of the two−dimensional signal space adapted to the dominant(More)
This paper presents a prototype of a 3D audio recording system named AudioSense which uses Wireless Acoustic Sensors to capture spatial audio. The sound is recorded in real-time by microphones embedded in each sensor device and streamed to a Processing Unit for 3D audio compression. One of the key problems in systems which stream audio data is end-to-end(More)
The new eSBR tool of MPEG-D Universal Speech and Audio Coding offers a great advantage in compression of high frequency content, however it produces audible artifacts for sounds whose pitch frequencies are strongly variable or exceeding the split frequency of eSBR. We propose an extension of the forthcoming standard by adding a high frequency sinusoidal(More)
The papers at this Convention have been selected on the basis of a submitted abstract and extended precis that have been peer reviewed by at least two qualified anonymous reviewers. This convention paper has been reproduced from the author's advance manuscript, without editing, corrections, or consideration by the Review Board. The AES takes no(More)
— The H.264/AVC is the most recent standard of video compression. In this paper, an original and efficient architecture of inter prediction block in an H.264/AVC decoder is presented. It is shown that the bit-serial arithmetic can be successfully used for interpolation filter implementation and the resulting architecture is fully pipe-lined. The inter(More)
