Hi,

I want to find peak frequency in a frequency interval like 2000hz-3000hz from adc.
i tried :

[adc~]
|
[lop~] --- [3000]
|
[hip~] --- [2000]
|
[sigmund~ -npeak 5 peaks]
|
[route 0 1 2 3 4 5]
|
[unpack 0 0 0 0 0]
|
[value]

but i couldn't get success.

How can i do this?

thanks

Isn't there any comment or answer, i don't want making my custom fft patch for finding peaks, [sigmund~] works very well

If you you're going to try filtering it first, the vanilla filters aren't going to cut it. They're only single pole filters, so they don't have a steep slope. You can try stacking them, or use some of the steep filters in iemlib. The Butterworth filters would probably be the best choice.

Thank you very much for your answer, i used [hp10_butt~] and it filters audio. But now i have problems detecting peaks. I have peak freqs on 2500hz and 2600hz, they occurs seperately in a random time, i want only find these peaks when they occur. Sigmund detects many peaks between 2000-3000hz but it cannot always catch my expected peaks(2500hz and 2600hz). Is there any another efficient way of doing this? Thanks
