Low bit-rate coding of high-quality audio signals An introduction to the MASCAM system G. Theile, G. Stoll and M. Link' The article explains how the bit-rateofa digital audio signal can be reduced, without impairing the sublective quality, by arranging to transmit only those details ofrhe signal which will effectively be perceived by the listener.

A new source coding scheme has been designed for low bit-rate transmitting of digital high-quality audio signals. It is called Masking-pattern Adapted Subband Coding (MASC). The bit-rate is reduced by using subband coding strategies in order to optimize the distribution of quantizing noise and bit-error noise across the signal spectrum with respect to masking effects of the …

3 that the input signal to the low bit rate audio encoder shall be emphasis-free and no emphasis shall be applied by the encoder; 4 that for digital sound-broadcasting emission, ISO/IEC 11172-3 Layer II coding shall be used at a bit rate of 128 kbit/s for a mono signal and 256 kbit/s (i.e. 2 × 128 kbit/s) for a stereo

Based on frequency domain techniques, coding of high quality digital audio with bit rates of down to 64 kbit/sec. is possible. The NMR (Noise-to-Mask Ratio) has been introduced for quality evaluation and optimization for low bit rate coding schemes. Real time implementations of low bit rate codecs and a measurement system have been developed.

Our experiments suggest that this method yields a nominal bit rate of 1 bit/sample for high quality audio compression. 1 1. INTRODUCTION In this paper, we present a novel method for high quality audio coding using a combined harmonic and wavelet representation. The audio signal is represented as t...
