-V 0
(~245 kbps), -V 1
(~225 kbps), -V 2
(~190 kbps) or -V 3
(~175 kbps) are recommended.-b 320
is an alternative to the VBR settings above.-V 4
(~165 kbps), -V 5
(~130 kbps) or -V 6
(~115 kbps) are recommended.-V 6
produces an 'acceptable' quality, while -V 4
should be close to perceptual transparency.--abr <bitrate>
(e.g. --abr 80).-V <number>
where <number> is between 0 and 9, 0 being highest quality, 9 being the lowest. (Note: The 'V' has to be a capital letter.)-V 2
-V 2.75
--vbr-new
, which enabled a superior VBR mode in LAME 3.97 and some previous versions, is no longer needed with LAME 3.98 and higher, as it is now the default VBR mode. However, if you're still using LAME 3.97 or older, you have to add --vbr-new
to your command line to use that mode.--preset <bitrate>
where <bitrate> (desired averaged bitrate in kbit/s) is a value between 8 and 320.--preset 200
-b <bitrate>
where <bitrate> (bitrate in kbit/s) must be chosen from the following values: 8, 16, 24, 32, 40, 48, 64, 80, 96, 112, 128, 160, 192, 224, 256, or 320.-b 192
--vbr-new
switch enabled the new VBR mode. This is now the default VBR mode, with the old mode being available via --vbr-old
. In terms of quality, the new mode appears to be better than the old, but reports of artifacts when using the new mode do exist. Despite these possible issues, the new mode is currently recommended due to both the speed and quality increases afforded by the new algorithm.Switch | Preset | Target Kbps | Typical Kbps[3] | Y Switch enabled by default | Lowpass[4] | Resample | Formerly Known As |

l3codecx.ax
version 1.5.0 or lower, as used by Windows Media Player on versions of Windows prior to Windows Vista. An August 2010 security update for Windows XP and Server 2003 upgraded this filter to version 1.6.0, which can play the problematic MP3s. Windows Vista shipped with the older version but Windows Media Player uses a different filter, and later versions of Windows don't have the old filter at all.--alt-preset
system was introduced in LAME 3.90. It was replaced by the --preset
flags in later versions.-Vx
quality system was introduced, allowing finer control over the desired quality level and bitrate. The --preset
switches were made into aliases to the corresponding -V
flags for the sake of backward compatibility. There is no difference between the output you get if you use -V2
or --alt-preset standard
.--alt-preset insane
