Hi
i'm looking for a lame.acm with the possibility to choose the preset , is avaible?

The ACM architecture doesn't cope well with VBR, so I'm afraid the presets are disabled in the ACM interface.

The acm codec is using the cbr/abr presets.
Vbr is disabled, as support is problematic under acm interface.

It is problematic, but not impossible (if preset selection is done through configuration dialog).

thanks..

but what a pity is not avaible,

The ACM interface is not meant for VBR. That's why ABR is preferred here, it's almost the same as CBR. And the presets give too different results to be usable with the ACM interface...

I recommend to encode the audio with LAME separately and then use something like mpa2wav to put the MP3 file in a WAV container.
