I am investigating the synchrony of multiple oscillations and I am struggling to identify the upper/lower frequencies relative to the half maximum.
Could anyone suggest a simple way to:
  • Identify the peak amplitude of an oscillation in a frequency range.
  • Calculate 50% of this peak amplitude.
  • Identify upper and lower amplitude values at 50%.
  • Determine the corresponding frequency of the upper and lower 50% values.
Any help would be greatly appreciated!

Take a look at the builtin fourier analysis which is just perfect for an application such as the one you describe.
