Not available for Linux

There´s a mistake, this excellent software is not available for GNU/Linux yet :( I was looking for a similar program for a lot of time, that is, a soft to manipulate mp3 easy, fast and simply and mainly, not decompress the audio to work on it and then compress it again! if anybody knows about an app with this features for GNU/Linux, please, tell me! I don´t want to use Wine :(

Thanks
(sorry about my speech)
