This is normal. The default frame length for mireventdensity is 10s.
ragtime.wav is shorter than that, so only one value is computed. In such case,
the value is displayed directly in the Command Window. This is what you get:
"The Event density related to file ragtime.wav is 4.6569 per second”
Cheers,
Olivier
