I'm trying to understand a paper but it has an equation in it that is lost on me.. I don't think it's very advanced but unfortunately I've never had much experience with this kind of thing.
(From The pitch of short-duration fundamental frequency glissandos, Christophe d'Alessandro et al, [pdf] -- equation below given as (1) on page 2).
$ p = \frac{\int_{t1}^{t2} F0(\tau) d\tau}{\int_{t1}^{t2} d\tau} $
The accompanying text is:
where $p$ is the pitch perceived, $F0(\tau)$ is the time-varying fundamental frequency, $t1$ and $t2$ are the averaging time limits.
Any pointers?
