8a9ae37fee timefilter: allow to evaluate at other times. 2012-04-04 14:32:44 +02:00

3073aadf2d timefilter: internally compute feedback factors.
The feedback factors for the timefilter are directly computed from
the expected period. This commit changes the init function to accept
the period itself and compute the feedback factors internally,
rather than having all client code duplicate the formulas.

This commit also actually fixes the formulas: the current code had
sqrt(2*o), but the correct formula, both theoretically and according
to experimental testing, is sqrt(2)*o.

Furthermore, it adds an exponential to feedback factors larger than
1 with large periods.

5dd35b43f1 Move timefilter code from lavf to lavd.
It's only used in the JACK device.

Fixes linking shared lavd with JACK enabled.
