If you look at the above 1st just to detect what is current noise I sample ‘silence’ max amplitude and that and a bit are used for dtections.
Don’t use the silence split just create your own splitting and writing to /tmp
Also like someone said put a bandpass around pip frequency to further its prominence and then strip out from silence with markers of position in original.

No.

What I propose ignores the pip frequency.

And how long is the silence between them?
