A fast quantization loop algorithm for low power implementations of MP3/AAC encoder is proposed. The proposed algorithm exploits the empirically-driven linear relationship of quantizer parameters, and it can reduce dramatically the maximum number of iterations needed in quantization. The resulting MP3/AAC encoder can be implemented in real time with a power-limited system.
