'lame' is an MP3 encoder. VBR is 'variable bitrate', which means that |
9 |
high-information sections in the input stream get more bits in the |
10 |
output bitstream, and low-information sections in the input stream get |
11 |
fewer bits in the output bitstream. An encoded song might use 192Kb/s |
12 |
for a few seconds, and then 32Kb/s for a second, and jump up to |
13 |
256Kb/s for a quarter-second before dropping down to 128Kb/s--but |
14 |
still sound to your ear like it was encoded at a constant bitrate of |
15 |
256Kb/s. All so that audio fidelity is maintained when there's |
16 |
something there to actually hear. |

Or, more simply: |
19 |
* 'lame' is an MP3 encoder |
20 |
* 'VBR' stands for 'variable bitrate', and offers a better |
21 |
size/quality tradeoff scale than saying "I want 192Kb/s" |
