       abstract = {In this paper, we re-visit an original concept of speech coding in which the signal is separated into the carrier
modulated by the signal envelope. A recently developed technique, called frequency domain linear prediction (FDLP,',','),
 is applied for the efficient estimation of the envelope. The processing in the temporal domain allows for a straightforward emulation of the forward temporal masking. This, combined with an efficient non-uniform sub-band decomposition and application of noise shaping in spectral domain instead of temporal domain (a technique to suppress artifacts in tonal audio signals,',','),
 yields a codec that does not rely on the linear speech production model
but rather uses well accepted concept of frequency-selective auditory perception. As such, the codec is not only  specific for coding speech but also well suited for coding other important acoustic signals such as music and mixed content. The quality of the proposed codec at 66 kbps is evaluated using objective and subjective quality assessments. The evaluation indicates competitive performance with the MPEG codecs operating at similar bit-rates.},
