TommyCat Posted July 25, 2018 Share Posted July 25, 2018 Finally getting around to doing a measurement (umik-1 mic, Mac, Audirvana). Getting a message “File not a valid calibration file” when try to load the .txt document that contains the mic calibration file. Seems to be a different message than others have been discussing. Sort of stuck at this point (however, looks like I could move forward if don’t use the calibration file but would prefer not to do that) Link to comment
Carl Kesselman Posted July 25, 2018 Share Posted July 25, 2018 I have managed to get this to work after editing out the high frequency points. I now have a chain working on the Mac using Roon/Loopback/Reaper. Its a bit tricky as it appears that loopback doesn't handle exclusive mode properly, but it seems ok. From a usability perspective, it seems that this plugin only version is going to be more complicated if one wants system wide application of Dirac or if your playback application doesn't support plugins (like Roon currently) Link to comment

This was not an issue in the prior plug-in version. Something seems amiss. Link to comment

TommyCat Posted July 25, 2018 Share Posted July 25, 2018 Ok found success in making measurements and uploading the calibration file for the Umik-1 mic. Fist, would like tho thank Flavio for his amazing support (as always). I redownloaded the mic calibration file from the minidsp website. The new download uploaded nicely into the Firac Live Processor. I was unable to run the measurements inside of Audirvana. I opened the Processor as Standalone and worked perfect. Have not played with the filters yet but the measurement process was I nice improvement over the previous version(s) Link to comment
TommyCat Posted July 25, 2018 Share Posted July 25, 2018 Ok, this program is becoming like golf. You think you have it and then frustration! I have successfully created a measurement/“project”. I created a couple of filters in addition to the base filter Dirac gives you. When I open the Dirac Professor and open my project, it shows the two filters I created on the left. However, when I select either of those filters, nothing changes - it is only showing the Dirac base filter. I would like to see the shape of the filter I previously created. Clearly I must be doing something wrong. in addition, how do you delete a filter previously created. Prior version on a Mac was Libray>Appliction Support>Dirac>Filters. From here you could delete. I am not finding this on the new version. Greatly appreciate guidance on these issues! Link to comment
TommyCat Posted July 26, 2018 Share Posted July 26, 2018 Figured out how to delete a filter once created. The “big red delete button” inside of A+: Audio Unit window when music is playing or preferences>audio units>configure. must have been exhausted yesterday to not see that. Link to comment
JezQ Posted July 27, 2018 Share Posted July 27, 2018 Very pleased to see the updates on your progress Tommy. I've had to pause my involvement with the beta as it is of no use to me unless system wide like the older version was. Not really interested in faffing around with virtual cable as suggested by Dirac. Really keen to install it again when the beta is more mature and has the expected functionality. In the meantime I look forward very much to reading about your and other people's experience with it. Link to comment
JezQ Posted August 28, 2018 Share Posted August 28, 2018 More than a month sìnce the last comment. Has everyone successfully implemented the new version now? Thoughts? Link to comment
flak Posted August 28, 2018 Author Share Posted August 28, 2018 Beta testers of standalone version received build 0.9.2 of Dirac Live (the calibration tool) while we now have beta 0.9.4 that has been distributed to Arcam beta testers but not to the standalone ones as we are waiting for a new version of the DiracLiveProcessor (the other necessary component) Flavio Warning: My posts may be biased even if in good faith, I work for Dirac Research :-) Link to comment
michelangelo Posted August 28, 2018 Share Posted August 28, 2018 Hi Flac, my beta version ends in 4 days. Is it possible to prolong it oder is there a new beta version? ♦ iTunes ♦ Audirvana 3.5 ♦ Dirac Live ♦ Dynaudio Connect ♦ Dynaudio Focus 200 XD ♦ Allo Digione Signatur Player ♦ Dynaudio Focus 600 XD ♦ Link to comment
dziemian Posted August 28, 2018 Share Posted August 28, 2018 When I installed the beta in a form of jriver plugin it sounded significally worse than the non-compressed sound or the old version I remembered. I tried to measure twice and finally turned it off as I could not listen to it. Previously the processed sound was clearly better than non-processed one and I loved Dirac. I dont want to compare more as I am in a process of changing speakers and I need a multichannel version. I will try to make some more tests once I set up new speakers. I will also try Audiolense this time. Macmini/ Jriver MC26 - Audiofire 12 - MSB-MVC-1 volume control - Cinepro 2k6 amp - Geddes Abbey speakers plus 4 x 10" Aurasound subs Link to comment

Interesting, I am using the new plugin for Audirvana and have had a similar listening experience; just can’t seem to get the sound as good as the previous version; maybe I’m just very used to the old sound and this is different. The measurement for the low-end frequencies was very different than the previous version (nothing changed in my system). Despite various target curves I have drawn finding the bass a bit more muddy (less tight). New version also does not have a volume slider in the processor to reduce potential for digital clipping; possible getting more distortion. Very much looking forward to the completed version 2 of the Dirac - plugin. Link to comment
michael123 Posted August 28, 2018 Share Posted August 28, 2018 And I like the new version much more. Previous had clipping issues, and I needed to use digital volume to reduce the signal. The measurement procedure is completely different now, maybe you can play with the mike settings to change the sound Link to comment

I was under the impression the beta version did not have it added yet. Would be very nice if not needed at all. Link to comment
wgscott Posted August 28, 2018 Share Posted August 28, 2018 At one point the older mac version did not have the slider, and there were folks complaining about excessive volume decimation/compression. Link to comment

Hi Michelangelo, dziemian and TommyCat we are not prolonging Michelangelo's beta version because the current beta build has flaws that will give bad results for anything except 48k. Also, care must be taken during calibration to make sure that is also 48k. That's why I think that dziemian and TommyCat findings are correct.

michelangelo Posted August 29, 2018 Share Posted August 29, 2018 Hi Flac, Can you estimate when there will be a new beta version?

Flavio Well, this explains why if you click on “audio settings” when the processor is first opened, and then selecting a higher sample rate (I.e 96khz) you cannot open your project (s). You get an error message. Also, I am not sure we can go back to V1 b/c mine, all of a sudden, became disabled because “no longer supported”. Thanks to Flavio, I found out about version 2. Hopefully this can all be resolved in fairly short order. Flavio, thank you very much for highlighting the 48 kHz ‘only” issue. Explains a lot and now don’t feel like I am going nuts! Link to comment
dziemian Posted August 30, 2018 Share Posted August 30, 2018 That may explain the unpleasant sound as my jriver' output is set to change all sampling to 96khz and if I remember right I measured at 48khz as there was no other option. If this is an issue, changing all sampling to 48khz should work, shouldn't it? PS. Is there a chance for multichannel beta soon so we can measure subs too?

SteveS1 Posted August 30, 2018 Share Posted August 30, 2018 Thanks to Flavio, I've got DiracLiveStudioBeta2_v1_1_0 working well with Audirvana +trial. I have an original AV license so will upgrade at the end of it. I have used old Dirac Live filters and created one by loading an old project from Amarra/iRC - all this worked fine. I've lowered the DSP gain by 6dB and the results are excellent sonically, I do get an occasional stop in playback when track hopping using the AV Remote but not often and not enough of a problem to spend much time trying to work out why. I haven't yet tried to create a new project. Will do that when I get an empty house and some time. Audirvana Plus/Dirac Live - Weiss 202 - Lavardin IT-15 - Art Emotion Signatures.

dziemian Posted August 30, 2018 Share Posted August 30, 2018 I am suprised that your old filters worked in new version and you liked the sound. There is a new algorithm in beta, therefore old filters should sound diffrent but not necessary in a proper way.

SteveS1 Posted August 30, 2018 Share Posted August 30, 2018 That isn't quite what I said, they work and are producing better than no filter sonics. The most successful (i.e. the one that sounds best to me) is without doubt the old project used to create another filter. Is this surprising? The measurements remain the same, presumably the new algorithms improve on optimisation. Doing precise like for like comparisons with two engines running the same filter is not something I intend to attempt without cause because even getting the level identical would be problematic, let alone the faff in changing them over.
