The Audio Extractor app is one of the most complete audio tools on App Store. Highly functional, feature-rich and beautifully designed, The Audio Extractor is a 6 in 1 audio tool that was recently completely redesigned and now it has lots of useful features all in one app! It wouldn’t be a complete audio app if there isn’t little entertainment it. This time the entertainment comes with a music memory game called Memo Tone. It is intended to entertain you, but also to enhance your brain and music learning and recognition skills.
