A small library for vector management and arithmetic in C++ using raw C pointer arrays, designed for simple audio buffer-shuffling. Also includes aligned malloc wrappers and a lock-free ring buffer.
The code can call out to vector arithmetic helpers (IPP, vDSP) in some places, and has loops written with an eye to auto-vectorising compilers, but mostly this is a convenience library rather than for performance -- it initially exists to give a fairly consistent API to useful functions over audio buffer arrays.
This code originated as part of the Rubber Band Library written by the same authors (see https://hg.sr.ht/~breakfastquay/rubberband/). It has been pulled out into a separate library and relicensed under a more permissive licence.
Generally expected to be vendored in to local project builds rather than being installed as a system library.
C++ standard required: C++98 (does not use C++11 or newer features)
To compile on Linux: make
To compile on macOS: make -f build/Makefile.osx
To build and run tests: as above, but add the "test" target - requires Boost test headers installed
