Summary
Vertical velocity records (8192 samples at 8Hz) to illustrate the use of smaller subsets of to compute FFTs. 50% overlap and hanning window applied to each fft-segment of data. The 15 FFTs example (cold color tones) uses 1024 samples (128 s) of records, while the 7FFts example (warm tones) uses 2048 samples (256 s) for each FFT.
