Large Value Jumps
How can I eliminate large value jumps?
It's for a pitchtracking (sigmund~) patch that obviously jumps around a lot when using a live audio input, I wish to eliminate these big jumps that occur, Im thinking something along the lines of a bucket object and an if $f1>$f2 object and perhaps a + object but I cant quite get my head around it.
Many thanks :)
If you're tracking a specific instrument, why not do a little filtering to cut off frequencies above the highest frequency you actually want to detect? Ditto with the low end. Better input, better output.
This kinda works but has anyone got anything better?

Hi gregory,
I alreacy tried the filtering prior to pitch tracking, the problem is when the signal is small (for example in between words or sounds), this means the pitch tracker cannot find a specific pitch and so jumps around wildly, I`m looking for something using Max rather than MSP to filter out the unwanted values as I think the pitch tracker will always behave this way no matter what.
Thanks for your reply
Johnny :)
i seem to say this every few years, but there's a third party object called 'lbyl' which can be useful in these kind of cases.
or to continue Gregory's train of thought- perhaps some kind of gate to kill off the frequencies in those *dead spots* that you are looking to avoid.
That sounds like exactly what Im after, thanks kthozoid.. I have used a noise gate to avoid the dead spots but I still get big jumps while sounds are playing. Many thanks though Ill check that object out now.. :)
