Bit Rate Mode
These offer four different ways to control the trade-off between the size and quality of the exported files.
- Preset: This gives you a choice of four presets recommended by the developers. Each preset is a combination of various encoding parameters as shown in the table below. These are the recommended, easy to use settings; choose one unless you have reason to experiment with other parameters. As a rough guide to the claims made for these presets, uncritical listeners with quality equipment may perceive a file encoded with Extreme preset to be indistinguishable from the original, and those with budget equipment should perceive little difference from the original file with Standard preset.
The Insane preset is, as opposed to the used by the other presets. Files encoded with Insane preset take a fixed 2.2 MB per minute, often double the size of Extreme preset, with very little audible improvement.
- -b is 32 and applies irrespective of fast or standard setting
- low pass values were incorrect. I show 3.99.3 on Windows but in 3.98.2, Extreme low pass was at a more reasonable 19500 - I haven't found any explanation of this decision in 3.99, only questions about it.
(correct for LAME 3.99.3 on Windows)
