Efficient audio compression based on the perceptual coding of spatial audio ... and PS [8]. This codec is regarded as the most efficient (stereo) audio coder available today, delivering ‘good’ quality at bit rates as low as 24-32 kbps, and ‘excellent’ quality around 48 kbps. The incorporation of Parametric Stereo in aacPlus v2 is.

Most significantly, being multimedia compression. In this paper, the focus is on the audio compression method. Audio compression method has two types: lossy and lossless compression. Vector quantization is an effective way of lossy compression technique. The important tasks in vector quantization are codebook generation and searching.
