I'm not sure how many of you noticed, but the visualizers are not that much in sync with the music that is being played - more precisely, the visualizers are slower.
I've seen where these delay values were stored, but I didn't really think too much about tinkering with them. However, I just did, after finding a way to do it easier, rather than just modifying the required part in the firmware, then packing the firmware, then waiting until the firmware flashes, and finally checking if the situation improved, only to find out that you need to adjust a bit more.
So now it's really nice to see the VU meters so in sync with the music (it also applies for the peak meter and spectrum visualizer).
