2012, that would be really interesting to try out but I can't compile though unless you have some guide lines for it. Regards.
Could you be more specific. What compilation errors are you seeing?
Guideline:
# Assumptions:
# 1] You have some experience with building software from source
# 2] soxr already installed with headers
git clone git://git.alsa-project.org/alsa-plugins.git
cd alsa-plugins
wget http://ompldr.org/vaWQzNg/Initial-soxr-lsr-support.patch
patch -Np1 <Initial-soxr-lsr-support.patch
autoreconf -fis
./configure
make # If you have errors in avcodec_* functions, then your ffmpeg/libav version installed is not compatible. Go back to ./configure and pass --disable-avcodec
make install
If all goes well, then you can add to "/etc/asound.conf":
defaults.pcm.rate_converter "soxr_lsr"
You can alternatively use "soxr_lsr_HQ", "soxr_lsr_MQ" or "soxr_lsr_LQ".
