An audio encoder regulates quality and bitrate with a control strategy. The strategy includes several features. For example, an encoder selects a quantization level within a range of quantization levels, where the selecting accounts for non-monotonicity of quality measure as a function of quantization...http://www.google.com/patents/US7263482?utm_source=gb-gplus-sharePatent US7263482 - Accounting for non-monotonicity of quality as a function of quantization in quality and rate control for digital audio
