Sound memos is a great productivity tool. It is the quickest way to take notes quickly and while on the move.
I recently started using Sound Shaper for Windows Phone 7 and it is very good.
It's free, it has a UI which may still need some improvements, but it's working, it comes with the right features, and overall it's working very nicely.
(I couldn't figure out the pitch feature but it doesn't do any harm either…)
So try it out, it's free, and it's working well: Sound Shaper.
(Sound Shaper is available for free from Marketplace here)
