I have questions about the “hightime” and “lowtime” settings in Revelation. For example, if you set the lowtime to -100% below a certain frequency, let’s say 140 hz, I suppose there will be a continuous low-cut curve down to zero (that is, zero decay) at 140 hz, and not a sudden drop down to zero. If my assumption is right, will this curve then start at 140 hz or end at 140 hz or will the middle of the curve be at 140 hz?
Anyone knows? the developers of this plugin obviously don’t like to explain things – at all.
Controls the reverb time for the low frequencies of the reverb tail. For positive values, low frequencies decay longer and vice versa. Frequencies will be affected depending on the Low Freq parameter.
Low Freq
Sets the cross-over frequency between the low and the mid band of the reverb tail. The reverb time for frequencies below this value can be offset from the main reverb time with the Low Time parameter.
IMHO this is quite sufficient for explaining stuff in a manual for users.
If you really want to know the details, i.e. how decay contouring is usually implemented in reverb algorithms, there is a lot of information out in the web, like e.g.
(As the Reverence manual is talking about “crossover frequency”, I suspect that it actually uses the multiband decay method, i.e. the signal in the reverb loop is split into three bands and positive or negative gain is applied to the low and high bands)
That manual wasn’t exactly easy to find IMO. Anyway, I suppose it’s a bit more clear now, even if I still think that the information regarding lowtime and hightime could be more detailed.
