Ratings and reviews

App works as designed 5 stars! Bad reviews = bad test case, app works perfectly! If testing a audio system with hundreds of frequencies, without proper setup the spectrum will just look like high volume noise. The app supports a second mic, using the internal mic will not work as it's frequency range will be limited, use a high quality external mic and adjust the averaging value to best for your environment. Nothing wrong with the app, user error! :)

Just tried this again, forgot that it was pretty much outdated and featureless.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.

As an audio engineer I need good tools. This tool has allowed my work to be better because the features on this app give me the tools I need to see what is taking place in the audible frequencies. It displays the frequency response in a logarithmic form and what is what we are used to as audio engineers. Also the ability to change the averaging makes me feel the real the response is extremely accurate, while also allowing me to see the change over a long period of time. Best tool I could ask for
