Just to let you know I released 1.1:

This is an unstable release. It brings many new features, some of which
are still experimental. The new features are:

      * a denoiser that removes most of the background noise and can be
        used before encoding (available as --denoise in speexenc)
      * adaptive gain control (AGC), which adjusts the volume to a
        constant level (available as --agc in speexenc)
      * echo cancellation (experimental, only available from libspeex)
      * A jitter buffer which handles packet buffering for VoIP
        applications (experimental, only available from libspeex)
      * an improved narrowband mode at 4.8 kbps (nonstandard mode, only
        availablefrom libspeex for applications that don't require
        compatibility with other software)

Please test this release and report bugs. If youÿre developing a VoIP
application, you are encouraged to try out these new features which will
help increase the quality of the speech transmitted
