PGGB / Offline

Upsample your files.
Listen later.

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.

What you need.

A computer for processingSee suggested Mac and Windows requirements.

These offline-processing guidelines use the default Precision Optimized Upsampling Engine with Precision optimized selected. Memory use does not grow with track length, and paging space is rarely needed.

Operating system

Windows or Mac.

64-bit Windows 10 or 11, or macOS 12 Monterey or later. Apple Silicon and Intel Macs are supported. Intel and AMD processors must support AVX2.

Processor and memory

Recommended configurations.

A comfortable all-round system

8 cores · 32 GB RAM.

A modern processor and a fast internal SSD are a comfortable starting point for a large library. Smaller systems can also work well.

This is a practical guideline, not a fixed minimum for every setting.

Offline PCM · up to 256-bit precision

16 GB RAM.

4-core processor

A starting point for PCM processing with the default engine. More cores can shorten processing time.

Once you have enough RAM, a faster processor and faster RAM usually help large PCM batches more than additional capacity.

Offline DSD · up to DSD256

16 GB RAM.

4-core processor

A starting point for DSD64, DSD128 and DSD256. Your chosen modulator also affects processing time.

Offline DSD · DSD512

24 GB RAM.

At least an 8-core processor

More cores can help with demanding settings and larger libraries. The selected modulator affects processing speed.

Offline DSD · DSD1024 and DSD2048

32–64 GB RAM.

More cores recommended

The highest DSD rates benefit from additional cores and memory, especially when you want faster processing.

Music files and storageEstimate the space for your processed albums.

Start with PCM or DSD music files, such as WAV, FLAC, AIFF, WavPack or DSF. PGGB saves new files with their metadata and artwork; a streaming subscription alone does not provide files for Offline processing.

Choose the output you plan to use and estimate the space for the new files.

Storage for upsampled files

Calculating…

Stereo files in the 44.1 kHz rate family. The estimate uses the file’s stored bit depth, not PGGB’s internal processing precision.

Compression assumes a 30% saving; actual file sizes vary with the music and output settings. Leave room for your originals, temporary processing files and future albums.

GiB and TiB are binary storage units. Drive labels usually use decimal GB and TB.
