No it's Evernote. For some reason, Evernote employees choose to use the lowest quality format possible, even for the premium version (at least use something decent like WAV for premium...at the very least).
Because of that, the voice recording on Evernote is total waste, and there's no point in using it when virtually every single other voice recording app on the Android market uses WAV. EVen when i speak loudly in a quiet environment it's still muffled and barely audible. Don't even bother using it in any real world situation because you won't be able to hear about 60% of what you've said.
