sweeps durations and types?

[cantigas]

I'm curious and I can't find this information online:
How long are the "long sine sweep" and "short sine sweep" tracks?
Are these sweeps simple log sweeps, or some kind of stepped sweep?

I've yet to rip the CD and analyse it, but they sound like log sweeps to me.

The short is like 1 second, the long is about 5 seconds. The short one is for the frequency response, long sweep for harmonic distortion.

thanks dcibel.
