About this app

An audio oscilloscope is a type of oscilloscope that is specifically designed to measure and display audio signals. Audio signals are electrical signals that represent sound waves. They are typically in the range of 20 Hz to 20 kHz, which is the range of human hearing. Audio oscilloscopes are used by a variety of professionals, including audio engineers, musicians, and technicians. They are used to troubleshoot audio problems, design audio equipment, and analyze audio recordings.

Features
•  Scope, Meter, & FFT displays
•  FFT peak tracking with readout
•  Quickly take screenshots
•  High contrast colors for view-ability

Permissions
This app requires minimal permissions, but must have permission to access and record audio from the device's microphone, as well as permission to write screenshots to the device's storage.

The user interface and graphics are impressive, but unfortunately, without a trigger control or horizontal time rate (sweep), it's not that useful as an oscilloscope, however the frequency domain (FFT) portion is usable without triggering or sweep adjustment. Due to the limitations of the phone mic/line input, it's only good for audio frequencies.

It's pretty decent for looking at spectrum frequencies although it lacks so features. Would be useful to be able to switch window functions I think. No indication of what it is actually using. I was trying to figure out what's going on with my guitar tuning and noticed that there seems to be a frequency jump every 2 frets according to the app.. but I am not certain if this is an artifact of the algorithms used or the guitar

This is not an oscilloscope. There's no option to adjust the sweep rate. It doesn't even indicate what that sweep rate is. So, if your signal doesn't happen to sync up with that, whatever it is, then you can't determine anything about your signal at all. Anyone who had ever operated a real oscilloscope would know this.
