You can install avidemux from the rpmfusion repositories: setting those up is easy if you follow the links from the yellow "Set-up Guides" at the top of the forum page.
avidemux is already installed on my system but i never used it.
Would you please tell me if it can crop first 20 seconds of an audio file and return the audio with exactly same quality?

so, i figured it out finally....
correct command is ...
ffmpeg -ss 30 -acodec copy -i inputfile.mp3 outputfile.mp3
it copies the same setting as of original file and crops first 30 seconds of it.
