I have been using this app for years its one the best.
Far too fascinating! Does what it says on the tin, and does it very well! I'm having way too much fun with this app. It's fascinating to see the patterns and complexity in everyday sounds. I'll admit that it helps if you know how to read these things. Not everyone is going to understand it. You probably need a physics or music or sound engineering background to get the full effect. Only limiting factor is that you can't scale or zoom in on certain ranges in the free version. Top notch!
Haven't found anything better And the premium version has most of the features people complain about this one not having. That said, it's kind of annoying that logarithmic isn't the default, and that there aren't any advanced analysis tools at all even in the premium version... But the thing I took off a star for is that it doesn't show the full spectrum captured by the input device, which seems like the bare minimum for a spectrogram with non-adjustable range.
Simple, effective. The biggest thing that would make this app complete would be the ability to upload a picture and generate a sound for it. No other app in the store has this capability or does it well. Any plans to do so?
Another nice toy and beyond. It's great having this tool in a portable device. It'll help understand how a spectrogram works for musicians and aspiring sound engineers. I'm not sure if the scale has been well calibrated, though.
Fascinating Works very well on Galaxy Note i717. I set it quietly on a table, and saw two weak lines at 18khz and 12khz in my living room. Hmmmm. by moving the phone around I located the 18khz line to my electronic dog fence controller, very strong. The 12khz was coming from my shut off plasma tv. A reviewer said it showed bats, can't wait to try it. Mike

Minor fixes and improvements.
