Recommended LAME

--alt-preset standard (~190 kbit/s, typical 180 ... 220)

--alt-preset extreme (~250 kbit/s, typical 220 ... 270)

--alt-preset insane (320 kbit/s CBR, highest possible quality)

For high quality on portable MP3 players, you may use --alt-preset medium (around 160 kbit/s). The medium preset is only available in the modified LAME3.90.3.

The difference between --alt-preset standard and --alt-preset extreme is seldom perceptible. Hence, the ideal balance between maximum sound quality and least file size is obtained using --alt-preset standard. This is the most recommended setting.
