Compare
Vespertine and Roon, compared.
Both play FLAC and DSD files with automatic rate switching, exclusive mode and local surround. Roon integrates streaming services and documents convolution filters; Vespertine is open source, plays SACD ISO images, and documents Apple Spatial Audio for local surround.
Compared from each player’s own documentation or source code. “Not documented” means the vendor doesn’t say either way, not that the feature is missing. Table last updated 29 October 2026; its cells were checked 9 to 14 October 2026.

| Apple Spatial Audio for local surround | Yes | Not documented |
| Hi-res file analysis | Yes | Dynamic range, loudness |
| SACD ISO | Yes | No (DSF/DFF only) |
| Room correction | Measured in the app (USB mic), or REW / APO and impulse-response import | Via convolution |
| Convolution / audio effect plugins | Yes (room correction) / No | Yes / No |
| Streaming services | No | Yes |
² Multichannel DAC output and receiver bitstream are experimental, untested on real receivers and multichannel USB DACs (one Sony TV over HDMI has been tested: see docs/DEVICES.md); reports wanted.
Which one
Which to choose.
Choose Roon if…
- You want streaming-service integration: Roon has it, and Vespertine plays only music you own.
- You want convolution filters in a general DSP engine. Vespertine’s convolution is for room correction.
Choose Vespertine if…
- You want source code you can read (Vespertine is GPL-3.0; Roon is closed).
- You want SACD ISO images played straight from the image: Roon’s supported-formats FAQ lists DSD only as DSF and DFF files.
- You want Apple Spatial Audio for your own surround files, or a check for upsampled “hi-res” files (Roon’s audio analysis measures loudness and dynamic range).
Vespertine is free and open source (GPL-3.0). Price isn’t part of this comparison, and sound quality isn’t ranked.
