PGGB / V9 · Beta
Current release: PGGB 9.1.42. Read the V9 guide ↗
The new engine makes PGGB’s high-precision processing faster and less demanding on memory. Start upsampling with as little as 16 GB RAM.
Memory use no longer grows with longer tracks, and virtual memory and paging no longer need to be configured.
V9 at a glance
Like the previous version, V9 achieves near-perfect reconstruction accuracy in the audible band. V9’s redesigned engine also reduces high-frequency distortion. As a result, listeners report a cleaner, more natural sound than in previous versions.
Learn moreWith V9’s precision-optimized engine, memory use depends only on processing precision, not track length. Newer hardware-accelerated libraries make processing even faster and reduce the RAM needed.
For Offline PCM up to 256-bit precision and DSD up to DSD256, start with a 4-core processor and 16 GB RAM. For DSD512, we recommend at least an 8-core processor and 24 GB RAM. DSD1024 and DSD2048 benefit from more cores and 32–64 GB RAM.
PGGB-Audio-Link (PAL) is a free endpoint program for the computer connected to your DAC. Send the processed music there from PGGB over your home network. PAL is the preferred network endpoint where available; use UPnP when PAL is not an option.

Live listeningFollow Roon brings track details and cover art into PGGB and follows playback changes made in Roon.
If you rename the Roon zone, keep “PGGB” in its name to help PGGB identify it. With several matching zones, PGGB follows the only one playing; otherwise it keeps its current match, or takes the first Roon sends if none is followed yet.
