based coder, where quantization and entropy coding are per-formed in the frequency domain to exploit psychoacoustic re-dundancies. While good broadcast quality has been reported for bit-rates around 300 kbps [7], the premise of this paper is that higher compression efficiency and better perceptual quality can be achieved by employing SVD in the frequency domain.

is a lossy compression technique that is based on the assumption that all white noise sounds similar to the human being. The technique is founded on detecting the “white‐noise” like frequencies of a given audio signal and coding their power and frequency

Frequency-domain coding using fast transforms can solve both problems. If the audio frame has dominant tones, than most of the energy in the frequency domain is concentrated in a few transform coefficients, allowing for efficient compression. If the same transform that is used for
