There are no ads you have to worry about with this app, it’s very straightforward to use, and it works exceedingly well with external audio interfaces like my IK Multimedia iRig 2, which is typically used with guitars and other musical instruments. Perfect for those of us who still like to repair tape decks, where precise frequency readings are essential, especially for motor speed and playback head azimuth adjustments. The app was definitely a big help for replacing the belts on my Sony cassette deck from 1996. 👍

A decent free FFT app. I’m not sure of its accuracy, but that may be a factor of the iPad microphone too. It has an easy to use display, and clearly shows the peak of the spectrum, as well as a view or the waveform.

A little tweaky in resizing bandwidth but VERY straight forward and very useful for live sound control. No ads.
