https://github.com/rabitt/pysox/issues/117#issuecomment-840093466 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.
