Table 2.2:
Features controlled by the -qual switch
| Feature |
Explanation |
| Soft time-domain filtering |
Use a high-quality time domain filter instead of fast MDCT |
| Best match sampling rate |
Use the best sample rate without regard to
filter running time. Adapting to this sample rate might use
CPU-intensive filtering. |
| Full huffman search |
Find the best huffman code book possible to encode
the spectrum of each frame. A few percent bits can be saved in each
frame, available for higher quality in following frames. |
| Many outer loops |
Shape the quantization noise very carefully. |
