I have mentioned several audio editors available on our favorite platform but OnLamp.com's John Littler introduces three more (I have mentioned Audacity several times already) that I have not covered here, such as Snd, Sweep and Traverso. (Check out the comments section for more tools).
Whilst I rarely do audio editing, I am looking for a tool that works like Audio Hijack Pro on the Mac, a tool that captures audio from specific applications. Now that would be great to capture those audio streams, right? :)
So, what is your favorite audio tool?
