No PDC on 'Dry' signal? (FX Dry/Wet Mix)

MessageAuthor

I just noticed that when you use insert effect plug-ins with (properly reported) latency, the 'dry' part of the signal is not compensated at all. So, whenever you set the Dry/Wet Mix to anything else than 0% or 100% (NB: the displayed values are rounded off; 0.49% is displayed as 0%, 99.51% is displayed as 100%), the resulting mix of wet and dry signals are out of phase. :( Is there anything I can do on my end to fix this? Is there some setting, option or preference that I have missed? If not, I think a Feature Request should be added to apply PDC to the dry part of the dry/wet mix - as an option, probably, REAPER-style.

The easiest workaround is just to make a duplicate track without the offending effect(s) on it and mix the dry signal in that way. I agree, though, this has bugged me in the past.

- please vote; (another) discussion thread added . (@mods: perhaps the brief discussion above should be be moved there too?)

Just tested it with Reafir using a plugin buffer of 32768. Works fine. If you disable PDC on the plugin then you get the doubling that you would expect with a buffer of that size but with it enabled there is no issue. What plugins and/or plugin format isn't working? Win8 x64 v4.402.

Another case of needing an engineering degree to walk across the bridge? This should work correctly without user intervention. Even more so given it's not necessarily audible. What chance for us amateurs?

Reaper's PDC for dry/wet mixing works fine here, as long as the plug-in itself reports the correct latency. as far as i understand, reaper (or any other host) does not measure the plugin's latency (too complicated or even impossible with some plugins) but the plugin reports its latency in samples. so reaper delays the dry signal by the reported amount of samples. some plugins report incorrect values or even 0. that's the plugin developer's fault then and there's nothing reaper can do. i have asked for the option to manually set the latency value for some plugins some time ago, but noone cared =) some plugins "mess" with the group delay / phase response that there isn't even a way to mix dry with wet without phasing. amp-sims for example or some multiband processors. an adjustable dry to wet delay would be awesome to find a sweetspot in such a case.
