I just learned that there are two new versions of my sound editor of choice, Audacity.
The 1.2.4 version is being described as the latest stable release, with some bug fixes from the last version.
Version 1.3 is rumored to have "hundreds of new features" but not necessarily stable.
I am told you can have both versions installed if you want to try.
Both are totally free. Unless things have drastically changed from the last version, you'll find Audacity to be one of the most powerful wav/mp3(with LAME plug-in)/ogg vorbis editors available at any price.
