Hello all I am not a newbie to linux but certainly a newbie to music.I have just started to use linux to analyse some music. What i intend to do is to connect my machine to some speakers and i needed some software with which i can control the tempo of the song.I mean i can reduce the tempo of the beats make the song slow or increase the tempo of the beats and make the sound fast.. Do we have anything like this in open source. Any help will be greatly appreciated Thanks abhishek __________________________________________________ Do you Yahoo!? The New Yahoo! Search - Faster.
