I would love to see some of that functionality to go into Blender, because that is a major cross-platform media workhorse already. The sequence editor is already very usable, but could use more audio-related features.

For me that would be useful since I normally never record anything for pure audio, but rather for Youtube videos. Others may appreciate the 3D Audio/animation functions already in Blender, with which you can design stereo or surround sound.
