Layer Target Ratio Quality @ Quality @ Theoretical
bitrate 64 kbits 128 kbits Min. Delay
--------------------------------------------------------------------
Layer 1 192 kbit 4:1 --- --- 19 ms
Layer 2 128 kbit 6:1 2.1 to 2.6 4+ 35 ms
Layer 3 64 kbit 12:1 3.6 to 3.8 4+ 59 ms

- 5 = perfect, 4 = just noticeable, 3 = slightly annoying, 2 = annoying, 1 = very annoying
- Real delay is about 3 times theoretical delay
