Recently changed in this version

This update improves the signal processing in general. Meanwhile, I have released my second app "liveBPM". If you are a musician or DJ, be sure to check it out!
- Smoother frequency curve which now also appears more "calibrated"

    I am a record producer and before I begin jobs in unknown studios I test 'em with FrequenSee playing MY orange noise. Have it on Android and iOS - the same perfection.

    Awesome app with a little expansion this could easily be a killer really. Used to tune my Thx home theatre and car system, two thumbs up

    So, how to use this? I mean, if I wanted to know the frequency of a sound, from this app, what should I look at? The highest point of the line?
