Do you have to extract 5000 samples (chunks of the waveform) or just one sample with 5000 elements (5000 time points)?
If you need 5000 chunks, how long are these time samples/chunks? The same length (like 1 second), or random lengths (random number of elements) like 0.1 seconds, 1.3 seconds, 3.2 seconds, etc.? And what about the starting point for the extracted sample? Are they chosen sequentially, or are the starting points randomly selected?
If you're just extracting one time period, and you want 5000 elements to be interpolated over that time period, then what is the starting and ending time of the extracted waveform? From element #1 to the very end? Or is it some smaller chunk of the full length original waveform?
