Hi Klaus,
Re: https://www.b4x.com/android/forum/threads/oscilloscope.13759/page-2

Today I shuffled through my computer and found a very useful example from Klaus.. the Oscilloscope.
The application is working like a charm.. it could have been commercial grade if speed of sampling was improved. But my question
is: Can it be modified to accept a signal from the microphone jack?

Thank you.

Do you mean the 4 way 2.5mm jack on phone phones?
What about if your phone does not have a 2.5mm jack?

My mistake.. I mean the audio socket
Just think about using the cellphone's microphone input as a signal fed into the oscilloscope chanel.

Sure. But not by me, I have quite some other projects on my to do list.
You can use the project and adapt it to your needs, all the project I post in the forum are open source.
Anyway, I am afraid that the sampling rate for audio signals will be too high for the display.
