Complete --alt-preset Commands for Lame

Since I am new here, but a long time user of Lame, I have a request.  I've searched everywhere for a complete list of the options available, when using the --alt-preset line command with the Lame encoder.  I use CDEX with Lame for all my ripping encoding.  I have a partial list of the --alt-preset commands like:

--alt-preset cbr n
--alt-preset standard
--alt-preset extreme
etc.

But, if you don't mind, please provide the complete list, and the resulting encoding action.  If this is already provided somewhere, then a link will be appreciated.  Many people are starting to discover --alt-preset, but it is really hard to find much documentation.  Thank you very much..

"lame --alt-preset help" will give you the following:


The --alt-preset switches are designed to provide the highest possible quality.

They have for the most part been subject to and tuned via rigorous double blind
listening tests to verify and achieve this objective.

These are continually updated to coincide with the latest developments that
occur and as a result should provide you with nearly the best quality
currently possible from LAME.

To activate these presets:

  For VBR modes (generally highest quality):

    "--alt-preset standard" This preset should generally be transparent
                            to most people on most music and is already
                            quite high in quality.

    "--alt-preset extreme" If you have extremely good hearing and similar
                            equipment, this preset will generally provide
                            slightly higher quality than the "standard"
                            mode.

  For CBR 320kbps (highest quality possible from the --alt-preset switches):

    "--alt-preset insane"  This preset will usually be overkill for most
                            people and most situations, but if you must
                            have the absolute highest quality with no
                            regard to filesize, this is the way to go.

  For ABR modes (high quality per given bitrate but not as high as VBR):

    "--alt-preset <kbps>"  Using this preset will usually give you good
                            quality at a specified bitrate. Depending on the
                            bitrate entered, this preset will determine the
                            optimal settings for that particular situation.
                            While this approach works, it is not nearly as
                            flexible as VBR, and usually will not attain the
                            same level of quality as VBR at higher bitrates.

The following options are also available for the corresponding profiles:

  <fast>        standard
  <fast>        extreme
                insane
          <cbr> (ABR Mode) - The ABR Mode is implied. To use it,
                            simply specify a bitrate. For example:
                            "--alt-preset 185" activates this
                            preset and uses 185 as an average kbps.

  "fast" - Enables the new fast VBR for a particular profile. The
            disadvantage to the speed switch is that often times the
            bitrate will be slightly higher than with the normal mode
            and quality may be slightly lower also.

  "cbr"  - If you use the ABR mode (read above) with a significant
            bitrate such as 80, 96, 112, 128, 160, 192, 224, 256, 320,
            you can use the "cbr" option to force CBR mode encoding
            instead of the standard abr mode. ABR does provide higher
            quality but CBR may be useful in situations such as when
            streaming an mp3 over the internet may be important.

    For example:

or "g:templame --alt-preset fast standard <input file> <output file>"
or "g:templame --alt-preset cbr 192 <input file> <output file>"
or "g:templame --alt-preset 172 <input file> <output file>"
or "g:templame --alt-preset extreme <input file> <output file>"
