Well, the post I was responding to actually said that they thought these OSS products were at least as good as comparable commercial offerings which, in the case of LibreOffice, is entirely untrue.

That's not to say when LibreOffice is viewed on its own merit's it's not a worthwhile product. And it might well be the best option on Linux... but Linux is a tiny minority of the desktop market.

On Audacity I tend to agree with you. I keep it installed even though I also have Ableton simply because, as a basic sample editor, or where I need to do a format conversion, or a quick top and tail, or some normalisation, it's actually the better tool for those kinds of jobs.

You can even use it as a multitrack recorder and sequencer at a push, but it definitely starts to fall apart as compared to commercial offerings at that point.

Still, as a sample editor, it's a great tool.
