Excellent app. Does the job. Needed this to identify feedback frequencies in the audio system at church. And also to measure pink noise - i.e frequency response in the room, cos the resolution on the RTA of our digital mixer was grossly inadequate, and impossible to use for any critical audio engineering adjustments. Excellent tool, wish one could adjust settings while still viewing the frequency response. Big thank you to the developer. Thanks indeed

Okay so I've been using this app for roughly 7 months. It has been invaluable in my line of interest ie the field of paranormal. The initial layout of the UI is very self explanatory, with the option to proceed further with advance options. It gives you the basis and understanding of the regular environmental sounds. In your location. Displaying visual examples of frequency, rather than just someone telling you... often seeming confusing to some. All in all, well worth the download. Thnx dev

Just tried this again, forgot that it was pretty much outdated and featureless. Really needs to get some useful additions, tone and noise generator calibration for mic, freeze and compare sweep that can be saved with some type of notation so you know exactly what you're loooking at. That's a problem with most of the audio apps, if you can save you can't label them so they have any use. Unless you take notes on everything it means nothing.
