Itry to remove all stereo information, leaving only the mono part of a wave, but with the internal LIVE-PLugin "Utility" i just can doo the oposit of this (remove all mono information, leaving only the stereopart of as wave )

Who can give my an Idea how to doo it.

you could use itunes to convert it to a mono .wav file.

There is no way to do this.

Click on edit, that opens your editor and then save as mono.

do you mean something like a m/s (mid/side) coder/decoder? like in seperating a stereo signal in two mono's? a signal carrying the mid (sum of left and right), the other carries the 'side' (difference of left and right (phase invert one))?

if that's what you want, i can link you to some discussions/how-to's...

how you can do it yourself
basics
device

if you happen to have a CW pulsar card, you can try this or make it yourself with Modular (maybe you can do it in reaktor as well... wouldn't know really).

haven't tried the Live utilty yet. maybe after reading some of these links, you might get the job done with this thingie.

Thanks for all your thoughts, but till now it doesn't help me. Maybe i should explane it more practical:

Some Drum-loops on the web I like very much, but most of the time they have a lot of cheep, childish sound effekts arround, what i don't like.

But the most good music-information (basedrum, snare, bass) is in the center und this shitty FX-Sound I here in the left / right -channels. So i tried with this Utillyty-Plugin and the result whas complete the oposite:

I could here the FX effekts because the mono part of the signal whas suppressed und not the stereo. So, how to do the opposite ????

Thanks for listening

This is a tricky one...
I dont think you are going to find an "easy" way of accomplishing this, however here is a stereo editor that just may make removing these ""cheesy effects" a bit easier than your average editors would.

http://home3.swipnet.se/~w-34826/

It is called Frequency, and is a sonographic editor. This means instead of seeing the audio waveform along a time line, you see the entire audio spectrum along a time line. With this style of editing, if you wanted to remove a bass drum, you would see it as a dark spot towards the bottom of the spectrum. Conversly, if you wanted to remove a hi-hat you would see it as line towards the top of the spectrum. Snare would be wider, and naturally, towards the upper middle of the spectrum. Once you start using it it will become quite intuitive.

P.S. Mac OS X only
