  1. That's a terrific tip! Thanks to both you and arglebargle!
  2. That fixed it! Thanks. I was on 3.24
  3. On a different subject; I noticed that files up-sampled to DSD512x48 by Pro are not showing up in Roon. So if I wanted to create a selection of my library up-sampled to DSD512 with Pro, I couldn't then use Roon to either manage that library or playback the files. I wanted to see how they would sound with just Roon playing them without HQPlayer Desktop involvement, since HQPlayer's filter and modulator have already worked their magic using Pro. Files up-sampled to DSD256 do show up in Roon. I should probably bring this up with the Roon guys, though I guess it's a corner case for them. Related to this I wonder if you could somehow add info to the files, perhaps in the comments field, which are created by pro to indicate that they are up-sampled/converted files by HQPlayer pro. This could then, perhaps, be picked up by programs like Roon to identify them that way, and distinguish them from actual, so called, "Native DSD" files or other PCM HIgh-Rez files. BTW, J River recognises the DSD512 up-sampled files just fine. So J River could be used as a library manager/player for these files.
  4. I could have explained a little better: This is going to Grimm LS1's using DoP to DSD128. If I leave "Auto Rate Family" checked, HQPlayer Desktop advances to the next track without a problem, … but the DSD512x48 files are now downsampled to 3.07 mhz which is not what I want. If I uncheck "Auto Rate Family" this is when the problem arises. The first track plays just fine as 5.6xxxx MHZ (DSD128x44.1); but it fails to advance to the second track. It's when I try to play that second track manually by clicking on it in HQP's interface that it gets stuck on the progress bar forever, or until I force HQPlayer to quit. Attached is the log file. I hope it helps. Thanks, Geoff HQPlayer.log.zip
  5. I'm continuing to use Pro with spectacular results converting to DSD512x48 at ASDM7 or ASDM7-512fs I determined that ASDM-512fs has slightly better PRAT, which suites some music very well, whereas ASDM7 has better apparent detail. Normally I play the results back using HQPlayer Desktop in "Direct SDM" mode to a T+A DAC8 DSD Yesterday I decided to listen for any benefits that may still result when using a DAC limited to DSD128 over DoP. The first track played fine and sounded pretty good with HQP Desktop down-sampling in real-time from DSD512x48 to DSD128. The second track refused to play though. It got stuck with the progress bar that normally shows when filters are being built as a result of change of sample rate within a playlist. I don't know if this is related to how HQP Pro produces the files or with desktop having issues when downsampling from DSD512x48 to DSD128. The same album plays fine to the T+A as a native DSD. Any ideas Miska? Thanks, Geoff
  6. Wouldn't it be possible to check the "Album" meta-data tag? If it is present and all the tracks have the same value for that tag, I think it would be safe to assume they all belong to the same album and are in the correct order.
  7. Just curious as to why this should be the case. If you add an album folder as the source and produce all your output files from that, why could the result be different than dragging and dropping all the individual tracks from that album onto HQPlayer Pro's playlist? (As far as the "gapless" aspect is concerned).
  8. Happy New Year everyone! The reason I started this thread on HQPlayer Pro is that I'm hoping we can use this to discuss the implications of offline up-sampling with HQPlayer's features for both true "pro" use and (keen) amateur use as an offline up-sampler. Some of these implications are applicable to other offline up-samplers as well. When considering how best to use these tools, the main question I've asked myself is… Do I really want to go to the time and expense of creating new permanent versions of some or all of the music I own with offline up-sampling, or do I just want to up-sample on an ad-hoc, temporary basis one, or a few albums at a time for each listening session? I'm leaning towards the latter approach for the following reason… Whatever offline up-sampling method I use, something better may come along in the near future. Do I really want to offline up-sample my complete music library or size-able chunks of it, when I might want to repeat the effort if something better comes along. For example, supposing Jussi comes up with new and, possibly better up-sampling filters/modulators in the future (not unlikely given his track record) would I really want to go through the whole process again? All I've upsampled so far is one track at just over 3 minutes to the most extreme level of DSD512 x 48 using poly-sinc-xtr + ASDM7. This yielded a file of just of 1gb and took approx 10 mins on my Mac Pro (2013) running Win 10 pro. A full album might end up at about 24gigs and take, perhaps 4 hours. Is it worth it? Based on what I heard, yes definitely! I used the first track from Anna Netrebko's Souvenirs album. The music was just "in the room" and I could hear things she was doing with her voice that I hadn't heard before. In a sense she seemed "less perfect, more human". There seems to be greater variety which might be glossed over at lower sample rates. I've heard this at DSD256 in real-time with HQPlayer Desktop; but this is the first time I've been able to hear it through my T+A DAC 8 DSD at the maximum DSD512 as that would be too demanding for any of the machines I have in house. So, I've decided my approach with HQPlayer Pro is going to be to batch up-sample just a few albums over-night, if possible, in preparation for a special treat of a listening session the next day. In a way that brings me back to the kind of discipline required for playing back vinyl and away from the huge choice of music at our fingertips with the streaming services and large local libraries. Of course that convenience is still there; but I will have decided to set aside the time to listen to those few albums at their best. The remaining question for me is, will I be able to bear to trash the resulting files after listening, or will I end up using this approach to build up a select library of DSD512 poly-sinc-xtr/ASDM7 up-sampled/converted albums. It'll be very interesting to hear from others on how they plan to use or are already using this tool.
  9. Hi Dirk, I didn't get that far before leaving for London and Christmas with my family. I just converted one file to DSD512 and played back the result in HQPlayer Desktop, without using roon. Will experiment a lot more with this when I get back and add further comments here. Geoff
  10. Ok. Thanks for that. I’ll give it a try.
  11. HQPlayer can’t accept an Airplay stream. So Airfoil won’t be an option. With Nicecaste you would have an input app (Spotify for example) and Nicecaste would create a url, like a Radio station url. In Roon you would then choose to add a new Internet Radio station, paste the URL from Nicecaste and Spotify would then be treated as a “radio” station by Roon and played through HQPlayer. I was hoping the server you mentioned would also allow a radio staion url to be generated, which you could add to Roon in the same way. Or if you can get hold of a copy of Nicecaste, it will still work on older versions of Mac OS (I believe before High Sierra) It’s just not supported. It might be worth you downloading a 14 day trial of Roon to test this. I’ll just add that Nicecaste is/was limited to lossy MP3 streaming. Your OGG/PCM stream from your server should be lossless quality. If you can get it to work in the same way as Nicecaste, I’m interested too ?
  12. Do you have Roon? Just wondering if you could use its Internet Radio feature to create a “station” based on the url from your server. Then the format wouldn’t be a problem. I’ve had some success with this with both Spotify and Apple Music, getting Roon to play them thru HQPlayer. That was using “Nicecaste”, unfortunately no longer supported on Mac
  13. I think it makes sense to have a separate thread on the new HQPlayer Pro. For those who haven't been following the posts on the HQPlayer thread, it allows you to record the results of using any of HQPlayer's up-sampling filters, ditherers/modulators for up-sampling/conversion between all supported formats. So a redbook 16bit/44.1 khz file can be converted to DSD at the highest sample rate supported by your DAC. In my case DSD512 with the most demanding filter and modulator combination. The result can then be played back on your player of choice as a native DSD file. I use HQPlayer Desktop for playback, with the direct DSD option checked. It is aimed at the pro market as part of the post-production/mastering process for creating final output files for distribution. In this scenario I imagine it will be more commonly used in the opposite direction of downsampling, say a DSD source file to a smaller PCM file for CD production use on streaming services. For the semi-pro/amateur users who want to up-sample convert from PCM to DSD there are a number of interesting implications. Going all the way from a PCM source file to 48x512 using poly-sinc-xtr with ASDM7, as I did yesterday is quite an extreme use. A 3 minute or so track ended up as at least a 1GB DSF file. The results of the one minute result I was able to listen to was tantalising. It meant I could use my Mac Pro 2013 model running Win 10 to play this 48X512 poly-sinc-xtr produced file through my T+A DAC 8 DSD, where the Mac pro can handle a max of DSD128 with real time up-sampling. If Chris and others here agree, I believe discussion of HQPlayer Pro would be better served by this separate thread and it would be a good idea to move existing posts from the HQPlayer thread to here. Geoff
  14. Thanks. I should have spent more time with the manual ?. Was too excited and impatient!
  15. Thanks. Yes, desktop couldn't access the DAC until after a reboot. OK, will check Task Manager next time. I did use the null output mode; but used the DAC for the input mode. I figured this is what I needed to do to have access to the filters, modulators and sample rates supported by the T+A dac to convert the input source file using poly-sinc-xtr with ASDM7 to 48X512.
