## Project history and usage

libbs2b is a small audio DSP library and tool set for applying Bauer stereophonic-to-binaural crossfeed to stereo material, mainly for headphone listening.

### Project history

The project grew out of headphone crossfeed practice rather than a new codec or container format. Its site ties the implementation to Benjamin Bauer's stereophonic-to-binaural work and later analog crossfeed circuits by Linkwitz, Chu Moy, Jan Meier, John Conover, and HeadRoom, then implements comparable behavior with simple recursive digital filters instead of FFT convolution.

SourceForge file records show public libbs2b release artifacts in 2006 and a 3.x line in 2009. The project stayed narrowly focused: a library plus command-line utilities for applying the filter to streams or files.

### Adoption history

libbs2b remained a niche audio package, but it reached the usual Unix packaging channels because it solves a concrete need for media players, audio filters, and headphone listeners who want crossfeed without a large DSP stack.

### How it is used

Package users normally encounter it through the bs2bconvert and bs2bstream tools or as a linkable library embedded by audio applications. Its practical value is applying crossfeed presets that reduce extreme stereo separation during headphone playback.

### Why package nerds care

For package nerds, libbs2b is the kind of tiny, single-purpose DSP library that explains why Unix package indexes are interesting: it packages a specific psychoacoustic trick as reusable plumbing.

### Timeline

- 2006: SourceForge file feed lists libbs2b 2.1.0 Windows binary artifacts.
- 2009: SourceForge file feed lists libbs2b 3.0.0 and 3.1.0 source release artifacts.
- 2009: SourceForge file feed lists ChangeLog.txt for the libbs2b file area.

### Related projects

- Related audio ideas include analog headphone crossfeed circuits by Bauer, Linkwitz, Chu Moy, Meier, Conover, and HeadRoom, which the project cites as design background.
