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.. :)
