Hello everybody!

I wanted to get some advice in regards to using pitch detection using the "sigmund~" object.

Essentially, I am trying to create a system that:

1. Detects incoming pitch
2. Records said pitch information
3. Plays back its own tune based on received pitch data (variable)

I'd like to emphasize that I am not talking about audio recording, but specific pitch in the form of midi data.

I've done some tests by playing samples into the object, and I have to say that it's pretty decent at being able to pick up the main melodies, but it is hard to have it working reliably.

Any further information or advice on pitch detection or any Pd objects/libraries I should check out would be tremendously appreciated.

Thanks everyone!

You might want to clarify the particular sound source(s) that you are concerned about and their qualities, ie monophonic (easier)/polyphonic (harder), more pitched(easier)/less pitched (harder), speed of notes, etc. Right off the bat, one parameter you can futz around with is window size, bigger window size = better frequency resolution but also worse time resolution.

I'm dealing with detecting monophonic signals, in this case a voice. I also want to capture the natural rhythm of human speech, record that information, and therefore have access to variable incoming speed of notes and so on. It needs to be able to detect natural speech patterns as much as possible and be able to replicate it (play it back through a speaker).

Ideally, this would be set up in a place where there might be background noise, but the patch should be able to distinguish the main melodic content from just background static.

Thanks for the recommendation regarding the window size! That is good information to know.
