1. Great for car audio enthusiasts.Enables me to view and record an audio signalI 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.It seems I need to look around and search for another application.
2. 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.
3. π€πan excellent teaching device, I love the visual combination of volume, pitch peaks, and wave shape that let me easily convey the dynamics of sound to myself and others.
4. Due to the limitations of the phone mic/line input, it's only good for audio frequencies.This is not an oscilloscope.
5. Anyone who had ever operated a real oscilloscope would know this.Great app, oscilloscope and spectrum analyzer in one.
6. I wouldn't use this app to find a wave form, but the FFT works faster than a real oscilloscope.
7. I use audio apps to a great degree and I am very familiar with how the display should appear.
8. Good job, guys! Moto G7 Supra.Inaccurate at times - when I play a sound of 11000 hz, it shows 4900 hz or something like that.
9. There's no option to adjust the sweep rate.
10. It doesn't even indicate what that sweep rate is.
11. Hopefully.The FFT runs blazing fast and tells you the peak value in realtime, Awesome! It pauses immediately when you hit the button.
