abr
average bitrate
cbr
constant bitrate Also forces CBR mode encoding on subsequent ABR
presets modes.

fast
Switch on faster encoding on subsequent VBR presets modes. This
results in slightly lower quality and higher bitrates.
highpassfreq=<freq>
Set a highpass filtering frequency in Hz. Frequencies below the
specified one will be cut off. A value of -1 will disable fil-
tering, a value of 0 will let LAME choose values automatically.
lowpassfreq=<freq>
Set a lowpass filtering frequency in Hz. Frequencies above the
specified one will be cut off. A value of -1 will disable fil-
tering, a value of 0 will let LAME choose values automatically.
preset=<value>

settings.
medium
VBR encoding, good quality, 150-180 kbps bitrate range
standard
VBR encoding, high quality, 170-210 kbps bitrate range
extreme
VBR encoding, very high quality, 200-240 kbps bitrate
range
insane
CBR encoding, highest preset quality, 320 kbps bitrate
<8-320>
ABR encoding at average given kbps bitrate
EXAMPLES:
fast:preset=standard
suitable for most people and most music types and al-
ready quite high quality
cbr:preset=192
Encode with ABR presets at a 192 kbps forced constant
bitrate.
preset=172
Encode with ABR presets at a 172 kbps average bitrate.
preset=extreme
for people with extremely good hearing and similar
equipment
