[Speex-dev] Speex 1.2beta1: Better, smaller, faster and more

[Jean-Marc Valin]

Speex 1.2beta1 announcement:

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.

Non-codec improvements include a extension (easier to use) to the echo
canceller API and a Speex-independent version of the jitter buffer. The
echo canceller should also be more robust to saturation in the capture
path. Last, but not least, the documentation has been updated.

Enjoy,
