The iPhones microphone is great for calls and the added voice memo feature helps when you need to record something quickly. But what if you find yourself in a situation where you want to hear something far away or something just isn't loud enough? This is where soundAMP comes in. Unlike the very limited voice memo app provided by Apple, soundAMP cone with a ton of customizable options. The app amplifies any sound going into the microphone. This is handy for, say, that time you really want to hear a bird call in the woods but it's a little too quiet. Obviously there are more uses as well. The full unlocked version of the app also gives users control over the frequencies, zoom, and allows for recording. Overall, the app really was a great improvement over the voice memos app and brings much more control over what you are recording. The initial version is free in the app store so check it out.
