Beja Expert Licensed User Longtime User May 10, 2021 #1 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.

My mistake.. I mean the audio socket Just think about using the cellphone's microphone input as a signal fed into the oscilloscope chanel. Upvote 0

klaus Expert Licensed User Longtime User May 11, 2021 #4 Can it be modified to accept a signal from the microphone jack? Click to expand... 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. Upvote 0
