Without specifying exactly why (because I didn't do it myself), here's what Ubuntu does. I think having fixed for ARM would make sense, especially if float support is in software. # Dynamically patch default configuration file ifeq ($(DEB_HOST_ARCH),armel) RESAMPLE_METHOD := speex-fixed-1 DEFAULT_FRAGMENTS := 2 DEFAULT_FRAGMENT_SIZE_MSEC := 10 else RESAMPLE_METHOD := speex-float-1 DEFAULT_FRAGMENTS := 8 DEFAULT_FRAGMENT_SIZE_MSEC := 10 endif -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic
