AB  - Maintenance of audio quality under the resource constraints on embedded platforms is very crucial. One of the major factors affecting the quality of Stereophonic Audio Coders is the method of distribution of bits across channels of a stereo pair. Conventional approaches use Perceptual Entropy, a computationally intensive metric, to distribute bits across channels. Improper computation or absence of this metric can severely degrade the audio quality. This paper presents an efficient and robust scheme to distribute the bits across channels, without using Perceptual Entropy, while still maintaining the audio quality. In the proposed scheme the bit allocation for both channels is performed simultaneously by allocating bits from a common bit pool. A detailed example illustrating this scheme is presented.
