Package: libzita-resampler1
Version: 1.3.0-2
Severity: wishlist
Tags: upstream patch

Hi,

Please find attached a patch for SSE-optimizing resampling of stereo signals;
it makes this more or less three times as fast on Intel systems, without
sacrificing any quality.

I talked to upstream about this patch back in the day, and he seemed happy to
accept it, but somehow just stopped answering -- I guess he got busy with other
things in life. It would be nice if we could get it into Debian nevertheless
(I want it for reducing CPU used in my realtime video mixer).

It is taken to be by Steinar H. Gunderson <sesse at google.com> (ie., work hat
from my ex-job), and licensed under the same terms as zita-resampler itself
(ie., GPLv3+).
