  1. In addition to what Rajiv stated, just as another point of clarification, I recommend gargle-blasted files to be played as is because PGGB already does the EQ and noise shaping.
  2. Strangely your Post just appeared, I don't think there is a equivalent filter (apples to apples), but perhaps you can try Sinc-M or Sinc-L on HQP and for samplerate in excess of 8fS, LNS15 for noise shaping
  3. 1. I am not aware of anyone who has tried this. The memory requirements for low sample rates are quite low so it should be easy for you to try on a PC even ith 16GB or 8GB RAM. 2. If you have a EQ profile in mind I can help you with this.
  4. Technically up to 65,535Hz to be pedantic, and up to 32bits (but 32bit encoder does not exist even though FLAC supports it)
  5. Though I have not tried it myself, I think Audirvana supports Wavpack for PCM too.
  6. That is correct, PGGB does not support mono track, you are the first to request it, I will add support in the next release.
  7. PGGB-RT for foobar2000 (foo-RT) is different from PGGB Offline you tried earlier, PGGB-RT is light weight (i.e less processor and memory intensive), trial never expires, it always lets you use up to 2M taps but for anything more the playback stops after 90 seconds. This is windows only version and installed as a foobar component for near real-time upsampling. Since your DAC can only go up to 192kHz, even memory requirements will be quite low so 4-8GB RAM should be fine too. PGGB.IT! V2.2 is an app that will let you turn the PGGB-RT into offline tool (i.e, lets you create upsampled files). PGGB-RT does not do DSD to PCM conversion and is also limited in the maximum number of taps to 1B.
  8. It is hard to say if your DAC will benefit, but it is easy enough to try the foobar PGGB-RT component and upsample to 192kHz.
  9. No, I have optimized it to the extent I can but if I find anything I can do to improve it further I will.
  10. The SDK can be used on Mac/Windows/Linux, though current implementation is on Foobar/Windows, Mac implementation in the future is possible (and currently being worked on), I can't proved ETA or any details for now.
  11. Understood, I have no intention of implementing DSD upsampling HQPLayer is the best there is in that regard.
  12. Thank you, as a point of clarification, DSD is not available right now for PGGb-RT/Foobar. But PGGB offline still offers DSD to PCM conversion even in trial mode.
  13. Based on initial feedback, I have improved memory, processing performance and also stability of PGGB-RT. There is now a new version v1.44. Also available as part of the foobar2000 Component repository (Resampler/Playback). The free PGGB.IT! App has also been updated to version 2.2 to allow offline remastering. Both now allow remastering up to 2M taps without requiring an upgrade.
  14. It currently cannot decode DSD, but it is a planned feature for the next release. It depends on the DAC, some DACs are able to play single bit DSD while others convert to PCM and play and the later can benifit from a software conversion. DSD vs PCM also depends on the mastering. Sometimes the PCM version is derived from DSD (often found in hybrid SACDs), in these cases DSD can be the better option. There are other examples (Patricia Barber's Clique is a good example) where the mastering was done at 32bit DXD rates and both the DSD and PCM DXD versions were created from this version. Here there should not be any degradation in quality going to PCM or even better using the original 32bit DXD. More often than not, unless the album was a direct transfer to DSD, if any processing was done during mastering it was converted to a intermediate PCM rate. Because processing DSD is a lot harder to do and most DAWs work with PCM. Bottom line it is hard to make any generalizations and provenance matters. More here: PGGB - FAQ (remastero.com) I don't think I can or want to convince anyone that software upsampling is for them or claim software upsampling is always a good option. There are DACs where software upsampling makes little to no difference. The possibility of additional processing introducing audible noise (because of active CPU, memory etc) exists for all software upsamplers. One has to weigh the the audible benefit the upsampled tracks bring to their DACs over audibility of processing noise (and possibly reduce processing by their DAC) and choose whichever sounds best. Again hard to generalize and one has to try and decide for themselves. I have kept the number of options to the bare necessities so as not to overwhelm anyone. I can safely say, 95% of the user just keep the settings at their default values. The rest of the settings such as sample-rate and bit depth numbers are DAC dependent. The idea is not to use different settings for different albums, but rather make a few adjustments to get the best out of your playback chain. For those who wish to tinker a bit, there is also an onboarding guide, though the guide is for PGGB Offline, the settings are the same for RT version so it can be used to navigate the settings. I agree, and we were concerned about it, so when PGGB-RT is busy processing the first track during the first few seconds of delay, a status progress bar pops up showing it is busy and it goes away as soon as the playback starts.
  15. Apologies if this has been covered but I'm just getting my feet wet with PGGB. I'm running an Anthem pre and using it's ARC (room correction). It will play DSD 128 and handle up to 32 bits and 384 kHZ. I have an i7 quad core and can get up to 32GB of RAM. Will PGGB work with ARC running? I plan to mostly convert redbook and I realize my computer is marginal to begin with.
