Equalization control with different sample rates

[oholiba]

When comparing two instances of the plugin, one oversampled, the frequency response is different when the equalization control (diffuse field/free field) is activated. This could be related to not updating the filter coefficients when the sample rate is different from 48kHz.

Test setup: Two instances of the plugin on two different tracks (the tracks contain exactly the same audio) in Reaper, one oversampled. Both tracks send to a third track, but one send is polarity inverted (this can be easily done in Reaper with a polarity switch in the send menu). The two plugins are synced with sync-channel "one". The third track remains silent as long as the equalization control is disabled, as the output of the plugins is exactly the same. When activating the equalization control, the third track is outputting a signal indicating there is a difference between the outputs of the plugins.
