What’s new in 9.1.45
Linearizing EQ above a frequency
You can now choose to linearize the phase response of any EQ filter above a frequency to avoid pre-ringing in low frequencies. You can also turn it off to keep it minimum phase or choose to linearize the full response.
Read the guide →Room, now in Live
You can now use Room emulation with DSD output, or PCM at 176.4 kHz and above with 107, 128 or 256 Bit processing.
Read the guide →Play from LMS or Roon (beta)
PGGB can act as a Squeezebox player (beta), receiving music from LMS or Roon with Squeezebox Support. With LMS, track details and covers appear automatically, and PGGB can control LMS playback.
Read the guide →OpenHome (beta)
With OpenHome, playlists continue even when you close the control app; PGGB and Remote can play, clear and step through them. Turn Follow foobar2000 off to make OpenHome available in foobar2000.
Read the guide →Play to squeezelite players (beta)
PGGB-Live can also send audio to squeezelite players, depending on your endpoint, PCM up to 1.5 MHz and DSD up to DSD2048 are supported.
Read the guide →Follow Apple Music on Mac
On Mac, follow Music’s track, artwork and sample rate. Control playback and seeking from PGGB or the Remote.
Read more →Icons that follow your Mac
On macOS 26 and later, PGGB follows Default, Dark and Tinted icon styles. The Mac PAL endpoint shares the icon; Windows and Remote icons are sharper too.

Upsampling on your computer.
Your DAC converts digital samples into sound. PGGB processes those samples on your computer before sending them to the DAC.
Get startedMany DACs calculate additional samples during conversion. They have to do it in real time within the limits of the DAC’s own hardware, which forces compromises.
PGGB moves this work to your computer, which has far more processing power and memory than a DAC. Process files in advance, or use Live while you listen.
Use music files you already own: WAV, FLAC, AIFF, ALAC, WavPack or DSD. Offline processing creates new files and keeps the originals.
To stream music, send audio from a supported player or network source through PGGB-Live. Qobuz and TIDAL work through compatible players or the PGGB audio driver.
PGGB upsamples your track by calculating additional samples between the originals, using up to 256-bit precision.
PGGB’s noise shapers and modulators then convert the upsampled track to the PCM or DSD format your DAC accepts, preserving the precision where you can hear it.
Try a familiar voice, the decay of a piano note or the texture of a bass string. Listen for a more natural timbre, clearer separation between instruments or a sense of depth.
Other listeners’ impressions are a useful guide, but the 30-day trial lets you judge PGGB in your own system.
One product / two modes
Offline or Live listening.
Offline
PGGB Offline saves upsampled copies of your music files. Play them through your usual compatible player after processing is complete.
When to choose Offline.
Why choose Offline.
- Process music in advance so your playback system does not have to do that work while you listen.
- Play your upsampled music on multiple compatible setups, including portable audio players.
- Play high-rate DSD even if your computer is not fast enough to process it in real time.
What to plan for.
- Allow time to process albums before listening.
- Upsampled copies need storage alongside your original files.
- Changing processing settings means creating new copies from the source.
- Your tracksOriginal music files
- PGGBProcess in advance
- Upsampled filesNew copies with tags and artwork
- Player and DACPlay on your setup or take them with you

Live
PGGB-Live upsamples music in real time between your source and DAC. It does not create a second library of files.
When to choose Live.
Why choose Live.
- Listen to your own files or a streaming service through a compatible player.
- Avoid storing a second, upsampled copy of your library.
- Try different output settings without preparing new files each time.
What to plan for.
- Your computer processes the music while it plays.
- Available rates depend on the computer, source, player and output connection.
- Playing to a network endpoint needs a compatible network connection.
- Your sourceFiles, streamed music, a player or a network source
- PGGB-LiveProcess while it plays
- Your DACDirect or supported network output
- Your musicControl from your desk or seat
Choose music in a compatible player. PGGB processes the signal in real time before it reaches your DAC.
What you need.
Play your own files directly, or send music from a compatible player or UPnP source. Qobuz and TIDAL can be used through a supported player or connection.
PGGB upsamples the music during playback, so you do not need to save a processed copy. The music still comes from your source.
A phone, tablet or another computer on the same home network can control PGGB-Live from a browser. No separate phone app is needed.
Choose tracks, manage the queue and control playback from your seat. The PGGB computer still processes the music and sends it to your DAC.
Remote is optional; you can also control everything at the PGGB computer.

Included in PGGB
Additional features.
Adjust bass, midrange or any other frequency band.
Equalization changes the balance of bass, midrange and treble. You can add warmth to lean-sounding headphones, reduce excessive brightness or tame a bass peak caused by your speakers and room.
Make a broad, gentle adjustment or target a narrow frequency range without turning down the whole track. PGGB supports parametric and convolution EQ in Offline and Live, including correction profiles you already use.
Equalization stays inside PGGB’s high-precision processing chain.
Because EQ is applied at PGGB’s full processing precision, it is transparent and does not add processing noise.
If a familiar voice sounds thin or bass overwhelms the music, PGGB-EQ lets you adjust the balance while keeping the sound clear and natural.
Parametric EQ.
Parametric EQ lets you choose which frequency to adjust, how much to raise or lower it, and how broad the adjustment should be. Use it for small changes to taste or a headphone correction profile.
Convolution EQ.
Convolution EQ uses a prepared filter that can contain multiple adjustments. Supply a filter made for your headphones or measured for your speakers and room, and PGGB applies it during processing.
Crossfeed lets each ear hear a little of both channels.
With speakers, sound from each speaker reaches both ears. Headphones usually keep the left and right channels separate. Crossfeed mixes a small, delayed and filtered amount of the opposite channel into each ear.
PGGB-ARC models some of this interaction, including the time sound takes to travel around your head and how it changes on the way. It can make the channels feel more connected while preserving stereo space.
PGGB-ARC runs at PGGB’s full processing precision, so crossfeed adds no rounding errors of its own.
In an older stereo recording, the singer may be entirely in one ear and the instruments in the other. Crossfeed can soften that separation and make the performance sound more cohesive.
Adjustable crossfeed strength.
A small amount softens hard left/right separation. Increasing it sends more of the opposite channel to each ear. The aim is comfortable stereo listening, rather than a mono blend.
Personal head measurements.
Your head and shoulder dimensions affect how sound reaches your ears. ARC can use personal measurements to refine its crossfeed model, and its virtual speaker angle changes the listening perspective.
Optional Room reflections.
Optional Room reflections add the early echoes and fading reverberation associated with listening in a room. Room and crossfeed work in Offline and Live. Room is available in Live with DSD output, or PCM at 176.4 kHz and above with 107, 128 or 256 Bit processing. Turn on Enable PGGB-ARC.
Use your phone to control PGGB-Live.
PGGB-Remote runs in the browser on your phone, tablet or another computer on the same home network. See the current track, manage the queue and control playback without returning to your desk.
The PGGB computer still processes the audio and sends it to your DAC. Remote controls Live playback and Offline processing; it does not carry the audio.
Remote also has a Process view for Offline file processing: select folders, set output options, start, pause or stop the job, and follow progress.
Choose the next track from the sofa while your computer processes the music and your DAC plays it.
Start with our recommended DAC settings.
A DAC preset supplies starting settings for your model, so you do not have to choose every setting before listening.
The DAC model, input, player and connection determine which formats and rates will play. Adjust the suggested settings as you find what suits your system.
