Awesome

This app has many options with all the extensions. Each extensions are can be purchased separately, but its worth to purchase them all.
It records very clearly and voice is amplified. It has great feature to store in local server, Dropbox or wireless file transfer.
It has AAC format which is almost 10 times file compression than wav file. I didnt notice big quality difference in AAC format. Great app to record long lectures.
