Result: with speex-float-1, the laptop lasted 26371 seconds, while with

the SSD, WiFi and display being on), or only 81 mW of extra power
consumed. And I don't yet know the standard error (will repeat the test
several times and report separately).
Note: for "real" mobile devices like phones, the impact will be more
significant. So I limit my "ignore complaints as invalid" proposal only
to laptops with Sandy Bridge CPUs.
Thanks for the test. i7 Sandy Bridge CPUs are not my primary concern
either (if you have an i7 CPU then you probably have a big battery to
fuel it, too), but what about Raspberry Pi, tablets, etc. And everything
in between.
That said, even for an i7 Sandy bridge, the question is how often will
you be annoyed because of resampler noises, vs how often will you be
annoyed because you've run out of battery.
As a related question, when you say that we have a worse resampler than
"proprietary OSes", that's only desktop OSes you're comparing us to, I
assume - not iOS, Android, etc.
Yes, I am currently talking about the desktop/laptop use case only, and
thus only about desktop OSes. I don't know how I would be able to test
iOS, but testing Android is indeed possible, because it can run in qemu.
