Would you be able to point me towards a shipping product/library that does this? It's easy to find examples of people hardcoding x64 assembly (x264, zlib, libyuv) but I haven't stumbled across anybody making good use of a high level wrapper.

There is entire high-lever scientific computing framework built using a SIMD wrapper: https://github.com/jfalcou/nt2.

Though I must note in this case the SIMD wrapper has significant problems. Due certain design decisions the wrapper performs suboptimally on mixed float-integer code on AVX for example.

Mentioned just in the parent, here is the link : https://github.com/p12tic/libsimdpp

Reaching 2.0 very soon (in RC phase right now), with support for VS which was lacking before.

Although it's way more than an SSE wrapper, the Eigen library is excellent in my experience and targets multiple platforms.

I had a look at the matrix*vector multiplication code for Eigen once and it was rubbish.
