I'd like to announce the second release candidate for Speex 1.0. It
fixes some minor bugs and reduces the binary size somewhat as the
codebooks were converted from float values to chars. As a result of
this, files encoded with earlier versions will have a slight increase in
noise (typically less than 1 dB) when decoded with the newer decoder.
As with the last release, you are encouraged to test it, beat on it, and
report bugs. If you want to know how you can make 1.0 better, have a
look at the Roadmap page (http://www.speex.org/todo.html).

I just compiled the current code in CVS with VS.NET on Windows and here are some minor annoyances: You might want to put the below code in a central header which is included by every file though NOT by speex.h so including speex.h doesn't mess with my warning levels. #if _MSC_VER #pragma warning(disable : 4244) /* conversion to float, possible loss of data */ #pragma warning(disable : 4305) /* truncation from double to float */ #endif <p>The headers define structs which are then passed to the library when using libspeex which is a problem as different alignment restrictions will cause problems. E.g. the default max alignment is 8 bytes with VC6/ VS.NET though we use 4 byte which means speex.h has to ensure that the alignment matches the alignment used to compile libspeex. The easiest approach is to do something like: #if SUPPORTS_PRAGMA_PACK #pragma pack (push,8) #endif // all struct definitions in speex.h #if SUPPORTS_PRAGMA_PACK #pragma pack (pop) #endif And then define SUPPORTS_PRAGMA_PACK for _MSC_VER, __ICL and __GNUG__ (can't remember whether it was 2.96 or 3.0 that added support for this pragma). <p>The last time I checked Ogg Vorbis had the same problem with regard to struct packing and it is very annoying having to deal with from a developer point of view. -- Daniel, Epic Games Inc. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

I did some modifications to address the problems you have. I think I
fixed the alignment problem without the pragma you suggested, but I
don't have the setup to test it. It's in CVS, so tell me if there are
still some problems left.
