People do the same audio math all the time, removing vocals for sampling, remixes, karaoke, stuff like that.<\/p>\n<p>My digital audio workstation is Ardour running on Ubuntu Studio 8.04. I&#8217;d prefer to do this in Ardour, but if I have to install something else, I can. (And I have the Ubuntu Studio audio suite already installed. I also have an OSX box, and can boot the Ubuntu box into XP, if I must, but it&#8217;s kind of a pain in the ass to get things across the systems.) Google has not helped me.<\/p>\n<p>Can I do this in Ardour? That would be optimal. I have Audacity running on the same Ubuntu box, tho&#8217; I&#8217;ve never used it. I also have Rosegarden and it seems to run, and a bunch of other things I don&#8217;t know anything about yet because I haven&#8217;t tried them but none of them seem likely to do this. (Drum sequencer, stuff like that.)<\/p>\n<p>If so, how? If not, what do I need?<\/p>\n<p>Thanks in advance&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8230;I even know how the math works.
