A Down-To-Earth Spectrum Analyzer and Oscilloscope
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. 👍
