hi, let's say i'm sent a 440hz tuning fork recording. i.e. someone gets a microphone, hits a tuning fork and waves it around the microphone. how would i go about using PD to analyze it for "main frequencies"? i mean, like, let's imagine that the 440hz tuning fork does not only play 440hz but also plays say 30 or 50 harmonic overtones of it, like a piano might (i guess?)
what would the process be of outputting this kind of frequency analysis data out of a recording, using PD?
