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

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.

Ratings and reviews

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.

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.

I didn't mind the .89p to get rid of ads for more screen space, but still in landscape on an 8 inch tab it is still a small waveform, I need to see just the waveform window in full screen without the unnecessary top border or controls, more options for colours i.e. a green waveform, and as others have stated it needs a sweep control.
