Just tried this myself, on a 2.2Ghz Core 2 Duo laptop, i'm getting 8% CPU using the default settings, with a noticable crackling/static sound at higher volumes (90 or above) -- so after reading this bug, I ran some tests to see if I could stop the pops.

The best result I found was speex-float-1, which caused no crackling on a HDTV .wmv file using the Flumotion binary WMV codec via Totem, at ~3-4% CPU instead, speex-float-0 caused the same file to playback slowly (although, rewinding or fast-forwarding through the movie caused the movie to play normally for around 30 seconds before the slowdown appeared again).

So CPU use was about the same using float-0 and float-1 here, float-1 caused no lag (if that's the right way to describe it) though.

Would it be worth running the same tests using -fixed-X?
