I am using Speex 1.0.4. I was very confused about why speex_encoder_ctl with SPEEX_GET_QUALITY *always* failed, until I read <http://lists.xiph.org/pipermail/speex-dev/2003-September/001896.html> from a whole year ago! Can SPEEX_GET_QUALITY be removed from speex.h and from the documentation (or actually implemented, whichever is easier :) Best! Reed
