How do you get the note from real-time instrument string sound?

@TIMAI2

would need to create an extension

But I'm afraid he is going to cut his teeth on it.
(is that how you say it in English? )

The extension can show real-time sound frequency from Instrument (with decimal Double) and detect the note from the frequency (String). We can use RECORD_AUDIO permission or similar. I need this for my tuner app.

Haven't you built an extension builder: "NEXT" ?

Perhaps JuanAntonio's

might help?

Uh.. Yes?

It wasn't successful though. The compiler now works, except while backupping stuff, half of the source code got deleted because of computer crashes
