PGGB & Antipodes

Support
1

Ive read quite a bit about PGGB and how amazing it is for stored music.

I see that theres a free trial. Sounds interesting, but I have no idea whatsoever how it works/connects with Antipodes Units.

Anyone here use/tried it?

PGGB creates upscaled music files. You play them like any other file.

I’m a big fan of PGGB. How much you’ll like it depends a lot on your DAC. I believe Chord DACs respond the best to it.

But where do you even start? Its not one of the server apps on your Antipodes Units.

I use HQPlayer and I see how that works and links with Antipodes and Roon. I have no idea with PGGB.

You run PGGB on a Mac or PC. Feed it music files and it will output much larger files. Copy these to your server and play them just like any other music file.

Never heard of RGGB. I used this for a while … Free Sample Rate Converter Tool Software - r8brain | Voxengo.

Now I use roon to upsample to 96kHz and my DAC upsamples that to 192kHz. It is not much load on the EXs CPU and reduces load on the DAC. No faff.

No doubt all these offer their own flavour.

The goal isn’t sample rate conversion. The goal is to more-perfectly reconstruct the digital signal. The more “taps” (or bigger the time window), the better the reconstruction. The higher sample rate is simply what’s needed to achieve that with PGGB.

This is HUGE - there is now a PGGB ‘Lite’. From the release notes of v7.1.42 posted here. (Note that v7.1.43 is now the current version.)

What has changed? During trial period and after the trial period ends, PGGB will now allow both 64bit and 107bit precision processing for PCM output perpetually without any restriction! As in 64/107bit precision for PCM will be free going forward. This is PGGB ‘Lite’, our way of giving back to this community and allowing more audio enthusiast to experience PGGB offline upsampling without restrictions. In terms of reconstruction accuracy, PGGB has come a long way since its release 4 years back. Call it trickle down, the current 107bit processing is more accurate than PGGB-AP 192bit precision released in 2022 and we are happy to share it for free with this community.

Hi Kenny,

Just trying to get the most out of this…it seems you can only process 5 tracks at a time? But that if you delete each 5 in the source folder you can get to process a whole album?

The version I downloaded also seems to suggest it expires in a month?

Any suggestions of making the most of this would be very welcome.

What’s the version number? Is it v7.1.43?

11

It’s now 7.1.44

It does say it is the full version that expires in a month, so if I stick to 107/64 maybe that will be okay.

Be great to do more than 5 tracks, though.

You found a bug. 7.1.46 has just been released with a fix.

Thanks, works fine now!

Nice improvement on many albums.

I am really growing to appreciate the PGGB versions of my favourite albums, even with the free Lite version. Really impressive.

I was wondering if this is close to what HQPlayer might also achieve?

I was also keen to try playing the files with Squeeze (I usually use Roon and Squeeze, because of multiple Zones), but wasn’t sure if it would play 32bit /384kHz files? I may have needed to rescan the library, so will try an again.

Squeeze will play up to 32bit/768k PCM and DSD512.

Great to hear. Which DAC do you have?
