You can use both.

Hey! What happened to "--alt-preset"?

The revolutionary --alt-preset system was introduced in LAME 3.90; it was replaced by the --preset flags in later versions. Starting with version 3.94, the -Vx quality system was introduced, which allows finer control over the desired bitrate; the --preset switches were made into aliases to the corresponding -V flags for the sake of backwards compatibility. There is no difference between the output you get if you use -V2 or --alt-preset standard. (Although adding --vbr-new is recommended for now, see above for details.)

More encoding options are available under the new system, such as -V1, which provides a level of quality between the old "standard" and "extreme" presets, or -V3, which is between the old "medium" and "standard" presets.

LAME 3.97 features more streamlined command line options, and it's recommended to stick to one of the values described in the text or shown in the tables above. You don't need to worry anymore about quality, settings, arcane combinations of switches, or presets.

For example, the following command lines will all produce the same output:

--alt-preset insane = --preset insane = -b 320 = --preset 320 = --preset cbr 320

(--preset cbr 320 is the exact same thing as --alt-preset insane, etc.)
