Anybody with years, perhaps decades, of DSP programming experience
plus testing in the real world - and all over the world - has my vote
of confidence. Furthermore, when this person writes spandsp, makes it
open source, and freely answers questions about it on public fora, I
am inclined not only to believe him but to trust his judgment.

Bottom line: thousands of people have chosen to heed Steve's advice.
He is well-respected in many technical communities. His reputation is
as solid as it gets. "Do what Steve says" is about the safest bet you
will ever make in this business.
