Bit rate is of course the main influence on quality. The higher the bit rate, the higher the quality. However, for a given bit rate, we have a choice of algorithms to determine the best scale factors and Huffman encoding (noise shaping). 0: Use slowest and best possible version of all algorithms. 0 and 1 are slow and may not produce significantly higher quality. 2: Recommended. 5: Default value. Good speed, reasonable quality. 7: Very fast, ok quality. (psycho acoustics are used for pre-echo and M/S, but no noise shaping is done. 9: Disables almost all algorithms including psy-model. Results as poor quality.
