Strange kinda bird you've got there... If you use a standard 44K1 audio interface, everything above Nyquist gets filtered out before conversion. You could in principle use a 1GhZ-bandwidth sample/hold clocked at 44K1 - this would effectively alias everything down to audio frequencies (folded over 1e9/44100 times). At that point, IF the S/H is clocked at a rate that's incummensurable withth erepetition rate of the signal you've got, you can then reassemble a non-uniformly sampled collection of points, leaving no space between them greater than 1/(2E9) seconds - then the sampling theorem says that you can theoretically reconstruct trhe original signal.
Don't forget a 1gHz low-pass filter, else if the bird hits higher pitches they will fold over :) M On Sun, Jun 05, 2016 at 04:47:51PM +0000, Jonathan Wilkes via Pd-list wrote: > Hi list,Suppose a bird sings a song in a frequency range around 1gHz.
