Hier die Lösung bzw. der Workaround:Bob Katz hat geschrieben:Then today with the help of Uli Brueggemann I've succeeded in getting Acourate Convolver to work in surround with Acourate ASIO and JRiver. Up to now it's only been stereo and I've implemented surround with a XO and parametric settings in JRiver options.
Now I've got tremendous latency in the audio, maybe more than 2.5 seconds. As you know, Acourate with its full FIR filtering and linear phase crossover and 65K filter length introduces tremendous audio latency. It's real hard for me to tell if the A/V sync correction is really working. I think it's bringing things closer (playing Star Trek Blu Ray) but the maximum negative (or positive) correction is -2500 ms. Matt, is there any way you can make that larger? Much larger perhaps. I'm just not sure until I zero in on it if I'm making a mistake, but I think it's getting closer and closer as I increase the negative value, but it looks like I need another second correction or even more. Can you please implement that in JRiver? God, the Acourate Convolution sounds good. If only I can get the sync. Nudge nudge .
Thanks in advance!!!!

Acourate Convolver and Acourate ASIO works very well for audio only. So I converted my Acourate filters to wav format (64 bit float), created a config file compatible with sourceforge and JRiver, and am now using JRiver's convolver for video playback.
Works great! A/V sync is now perfect and consistent at 0 ms. And the sound is great too. Acourate's filters are the best-sounding out there, in my opinion.
Also für reines Audio mit Frequenzweiche und Convolving arbeiten JRiver 18 und Acourate erfolgreich zusammen. Bob Katz schreibt, daß er hiefür seine Musik in WAV Format abgelegt hat. Ist dieses Format zwingend oder geht auch FLAC? Ich vermute WAV-Dateien sind schneller zu verarbeiten, da das Umwandeln beim Auslesen entfällt.
Wenn ich in JRiver ein Surround System einrichte (Satelliten, Center, Subwoofer und Rears) erreicht Bob Katz mit dem Acourate Convolver kein Lip Sync (Audio und Video lippensynchron). Er greift hier zum Workaround den Convolver von JRiver einzusetzen. Wird der Acourate Convolver noch weiterentwickelt, um auch Surroundsignale verarbeiten zu können? Bob Katz schreibt von fehlendem time lock zwischen JRiver und Acourate. Es wäre schön, wenn dies zukünftig möglich sein wird.
