Record It

RecordIt is a sound/voice/microphone recorder that lets you record in both 3gpp and wav format, so you can choose your preferred quality. You can also send your recordings via email, dropbox +++ if you need (just click and hold on the file you want to send).

In settings you can choose if to record in 3gpp for saving storage space, or wav for high quality. Here you can also choose what sample rate you want for the recording.
You can choose your own file prefix, and select to auto-save for fast and easy recording.
Settings also allows you to prevent the screen from turning off while the app is open (as long as the app is in
the foreground).
