[PD] hardcoded samplerate in audio example

 Sure, I could even make a PR if you like, I've attached a screenshot of the part from the patch where samplerate is hardcoded, on the second trigger outlet connected to [read-sample].
More confidently, I don't know how this could actually work with the [unpack s f] thing.

 The second screenshot is a correction that makes this patch compatible with any samplerate soundfile.

I've made this correction on apple silicon with pd 0.53.0 downloaded on official site but I guess this would happen in any version since this patch exist, and I've figured it out on compiled raspberryOS's pd 0.54 using sources cloned from pd's official github.





Best,

Pat

PS: thanks a lot for the else external, particulary the bandpass filter.
