With Max Waveform size
Waveform length = 5e-05 sec
Max Frequency   = 20.0 kHz
Speed           = 203.2 m/min

With your defined Waveform size
Waveform length = 3.74e-05 sec
Max Frequency   = 26.7379679144385 kHz
Speed           = 271.65775401069516 m/min

With your existing errornous Waveform size
Waveform length = 0.0002 sec
Max Frequency   = 5.0 kHz
Speed           = 50.8 m/min
