This release splits the speex codec library and the speex DSP
library into separate source trees. Both projects received build-system
improvements, bugfixes, and cleanup. The speex codec's VBR tuning
was improved, while the speexdsp resampler got some NEON optimizations.

1.0.x versions. Pulseaudio (which I am working on) requires
this version; moreover, the 1.0.x releases are deprecated.
The ChangeLog is not kept up-to-date, but here are some highlights:
1.2rc1
--------
Again, this new releases brings many improvements. The RAM requirement for
wideband has gone down drastically (i.e. more than 2x). A new resampler
module has been added, providing arbitrary sampling rate conversion --
fast. The echo canceller has also been improved. A bug in 1.2beta1 that
made the echo canceller unstable has been fixed. The echo canceller should
now converge faster, be robust and tolerant of incorrect capture-playback
synchronisation. The preprocessor has also been greatly improved. Not only
should the quality be better, but it is now fully converted to
fixed-point. At last, early TriMedia support (incomplete) has been merged.
1.2beta3
--------
The most obvious change in this release is that all the non-codec
components (preprocessor, echo cancellation, jitter buffer) have been
moved to a new libspeexdsp library. Other changes include a new jitter
buffer algorithm and resampler improvements/fixes. This is also the first
release where libspeex can be built without any floating point support. To
do this, the float compatibility API must be disabled (--disable-float-api
or DISABLE_FLOAT_API) and the VBR feature must be disabled (--disable-vbr
or DISABLE_VBR).
1.2beta2
--------
This release adds support for acoustic echo cancellation with multiple
microphones and multiple loudspeakers. It also adds an API to decorrelate
loudspeaker signals to improve multi-channel performance. In the bugfix
department, there are fixes for a few bugs in the echo canceller, jitter
buffer and preprocessor. At this point, the API for 1.2 should be stable
and only a few very minor additions are planned.

All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".

* Headers are now in ${PREFIX}/include/speex/ (but a copy is still
in ${PREFIX}/include for compat reasons).
* Pseudo-gapless playback (i.e. playback has the same number of
samples)
* Fixed a potential bug (unconfirmed) that might cause a segfault
in special circumstances.
Also includes a shlib major bump, so update DEPENDS in buildlink3.mk.

In this bugfix release: a fix for a multithreading bug and a
correction for an underflow problem that could slow decoding
dramatically on x86 processors.

|
Just a bugfix release. This update adds soundcard support for
Solaris and the BSDs as well as minor bugfixes and a documentation
update.
|
|
This release fixes several minor bugs that were found in version
1.0 as well as a major bug in the wideband encoding. This makes
files encoded with 1.0 play with lower quality on 1.0.1 decoders.
|
|
The bit-stream and API have been frozen in this release.

Moved Speex to Speex-mixedcase in the repository [schmonz 2007-06-07]
