Hi

Anybody looked at speex 1.2 (speex 1.2beta1 that is)?

The download page reads ( http://speex.org/downloads/ ):

Current Unstable Release (recommended)
1.2beta1

This new release brings many significant improvements. The quality has
been improved, both at the encoder level and the decoder level. These
include enhancer improvements (now on by default), input/output
high-pass filters, as well as fixing minor regressions in previous 1.1.x
releases. A strange and rare instability problem with pure sinusoids has
also been fixed. On top of that, memory use has been greatly reduced,
especially for fixed-point and narrowband. The fixed-point narrowband
encoder+decoder memory use has been cut by more than half, making it
possible to fit both in less than 6 kB of RAM. In general, CPU
requirement had gone down, especially for the fixed-point port. The
Blackfin port has been speeded up significantly, thanks to David Rowe.
There are also a few fixes for the TI C5X DSPs, as well as better
support for C++ compilers and crappy MS compilers. Oh, and before anyone
starts worrying, the format (bit-stream) itself has not changed, so
Speex is still compatible with version 1.0 and will continue to be in
the future.


However it neglects to mention that the speex library is now
libspeex1.4.0 instead of libspeex1.2.0 as before. Is it compatible?

Anybody tried it?
