In audio communications over a lossy packet network, packet loss conceal- ment techniques are needed to mitigate a user's frustration when perceiving the deterio- ration of the quality of the decoded signal. Multiple description coding (MDC) is a useful solution to this problem. In this paper, we describe an MDC method for concealing packet losses for wideband sound signal streaming based on the sample splitting method in the time domain and encoding by an MPEG-1 audio layer III (MP3) encoder. To enhance the quality of the restored signal, we applied a Wiener filter to the higher frequency part of the restored signal. Experiments were conducted to compare the proposed method with several conventional methods, conrming that the proposed method showed higher quality results than the conventional methods for a range of bit rates from 128 to 192 kbps when there were heavy packet losses.

In many applications, Compression techniques can be classified into one of two such as high quality audio transmission and storage, the target is to achieve audio and speech signal codings at the lowest main categories: lossless and lossy. Lossless compression possible data rates, in order to offer cheaper costs in terms works by removing the redundant information present in an of transmission and storage. Recently, compression techniques audio signal, but preserving its quality and the complete in- using wavelet transform have received great attention because tegrity of the data. However, it offers small compression ratios, of their promising compression ratio, signal to noise ratio, hence it can be used if we have no stringent requirements; and flexibility in representing speech signals. In this paper we examine a new technique for analysing and compressing furthermore, it does not guarantee a constant output data rate, speech signals using biorthogonal wavelet filters.

  • Speech and Audio Coding - a Brief Overview
    Speech and Audio Coding - a Brief Overview U. Heute Inst. for Circuit and System Theory Faculty of Engineering, Christian-Albrecht University D-24143 Kiel, Germany Abstract The historic „coding gap“ between (narrow- and wide-band) high-rate and (narrow-band) low-rate coding of speech has been filled more and more during the past 15 years. The GSM coder of 1990 was a very important step right into the gap, and it caused more research towards better quality and higher compression, which, together with other activities world-wide, closed the gap. The concepts behind this are explained, with a stress on the basis of the final break-through to good quality at medium-to-low and even wide-band speech at medium rates. The same concepts followed for speech were also applied to music, with some strong differences in the results: While time-domain approaches prevail for speech, frequency-domain coding was successful for audio, and it was accompanied by much more exploitation of psycho-acoustic effects. n i Speech Coding and the “Coding Gap” H o (z) ai z computes a linear combination i1 In the “classsical” speech-coding literature, “high- of past signal values as an estimation of the next rate” and “low-rate” codings were discriminated: n While digital speech transmission or storage was sample according to x ai xki , which is sub- possible with “telephone quality”, i.e., a bandwidth i1 of 300...3400 Hz, a sampling rate f = 8 kHz, and a s tracted from the actual samplexk , yielding the signal-to-noise ratio (SNR) of 35...38 dB, via difference or residual signal d x x from a various schemes between log.
