Work perfect

I just downloaded this app because i wanted to identify a mysterious high-pitched tone that was audible in my house. It worked great. The tone was clearly visible as a peak around 6400hz, and then i was able to confirm using a tone generator. I'm just a casual user, but the app present a feature set that would appear to satisfy more serious users too. I recommend this app and works great.

Detailed Bass and treble analysis is lacking

Gives almost no information below 70 hertz. I am trying to decide whether I need a sub woofer and how much my speakers roll off below 70hz. It shows a straight response from 70 to zero which is wrong and you can't select a reading below 50. Has the same problem at the upper end of the audible range. Fine for mid range analysis I suppose but this usually not where the problems are in audio systems.

I am really impressed

I've used bar graph audio analyzers on the iPhone and the one in this app is as good as any I've seen, but the real winning feature is the FFT display. It allows ready identification of the exact frequencies that are the components of the sound you are hearing.

Highly recommended.
