bqvec | small library for efficient vector

bqvec is a C++ library. bqvec has no bugs, it has no vulnerabilities and it has low support. However bqvec has a Non-SPDX License. You can download it from GitHub.

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 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: C98 (does not use C++11 or newer features).
