This app makes it easy to see just how music—or any other sound—is composed of different frequencies. (Of course there are timbres too, which are harder to interpret.) Sing to it, play with your voice, an instrument, a rubber band or a tin... It's fun! Show more

Turn this on while listening to music, people talking, or while waiting for the commercial break to end on TV, and then prepare to smile a lot!

everyone should have this app, unless you're cool with 'thinking' you sound just like your favorite artist when in actuality, god kills kittens everytime you open you mouth in sing song... what i mean is; if you're tone deaf like me, this visual aspects of this app are beneficial beyond description (further description) Show more

The latest rev of this app has really made a good thing great. The auto gain adjust has settled down, and the spectra are clean even for quiet sounds. The octave arrangement is awesome. Stay curious. Show more

I've been having a lot of fun playing with this app. I'm learning to play guitar and wanted to find a way to be able to visualize some of the music theory I've been learning and this very uncomplicated app helped me do exactly that. One of the other reviewers said that he found it disconcerting that it displays activity even when you're not doing anything, but it was pretty obvious to me that the app is picking up white noise when there's nothing else to pick up. I think that's actually pretty cool! Show more

Not sure about the accuracy, but it sure is cool. It's great for toning with voice for self and with group. Particularly cool if you like to play with sound frequencies and magical when working with overtones. Show more

Well, I can say it's a great idea, because I had the very same idea. I haven't written such an app yet, but I intend to. Some of the problems I anticipated are realized in this app. One of them is that FFT divisions don't line up with musical notes well. FFT is linear, and sound is logarithmic. You can see this by looking at the spiral. The higher notes have many dots between them. The lower notes each share a dot. The result is that it is somewhat useful for middle C and higher, but the octave below middle C is passable, and octaves below that are not that useful. This is very apparent when listening to music. The melody is usually easy to follow, but the bass line is muddy, if even discernible at all. Ideally, it should dance well visually with the melody. This may require some sort of encoding to a logarithmic data set where the FFT can be applied. Having said all this, I will be bringing the app to the club the next time I go to listen to some music. An FFT with finer resolution would also solve the problem, but, of course, there is a trade off between FFT resolution and performance. Use too high a resolution, and you won't be able to use a high enough sampling rate. I'd also like to see things besides octaves modeled. For example, thirds and fifths are important in music, too. These could be modeled with tighter spirals. Or maybe dots of a different color shown third away, etc. There are all sorts of possibilities. Show more

Brilliant concept but it doesn't work right. Even in a silent, quiet room it's display is reacting like I am standing in the middle of a marching band that's playing at full volume. What's with that? Two stars for the design concept but that's all since it really doesn't work right...at least on my New iPad. Glad it was free. It should support landscape mode and have a maximizable screen display the removes everything except for the actual meter graphics. A hold from time feature that has already suggested would be a good addition. Also, the help doesn't explain what the small, thin white lines are that shorten and disappear. Show more

Fabulous effort here by Secret Base and at a fraction of the price of competing apps. Well...not technically a fraction, I guess, since it's free.

Accurate and with an innovative way of showing pitch information. Brilliant!

Very very clever design. Would love to see a decaying hold feature to get a better grasp of frequencies over time. Charge me for it.
