Compare

Vespertine and foobar2000 for Mac, compared.

Both play FLAC with exclusive output. In the hands-on test on foobar2000 2.26, DSF, DFF and SACD ISO files failed to open without extra components; Vespertine plays them. foobar2000 for Mac documents Audio Unit DSP, which Vespertine does not host.

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.

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.

⁴ Tested on foobar2000 2.26 (macOS 27.0.1), with no components: DSF, DFF and SACD ISO files fail with “Unsupported file format”. DSF and DFF play only as 352.8 kHz PCM after installing FFmpeg separately and adding them to its FFmpeg Decoder Wrapper; SACD ISO still fails.

Which one

Which to choose.

Choose foobar2000 for Mac if…

  • You want Audio Unit effect hosting: the foobar2000 for Mac change log documents “Apple Audio Unit DSP support”. Vespertine does not host effect plugins.
  • You already use foobar2000 and its settings, and only play formats it handles without extra components.

Choose Vespertine if…

  • You want DSD and SACD ISO files to play without setup: in the test, foobar2000 2.26 refused them with no components installed.
  • You want an analysis of hi-res files (foobar2000 for Mac has a live spectrum only), a signal path, or room correction.
  • You want source code you can read (Vespertine is GPL-3.0; foobar2000 is proprietary).

Vespertine is free and open source (GPL-3.0). Price isn’t part of this comparison, and sound quality isn’t ranked.
