Dear All, I would like to have following clarifications regarding the Speex. 1. I have downloaded Speex-ver1.1.5.tar.gz from the site "http://svn.xiph.org/releases/speex/". I tried to open the speexenc and speexdec workspace. I get the message window displaying ..\..\speexenc.dsp "This make file was not generated by developer studio" Continuing will create new developer Studio Project to wrap this make file 2. I want to know whether the speex encoded data must be in "Ogg format" before giving it as input to the speex decoder as downloaded from the website? 3. Can a older version of speed encoded speech data can be decoded using a new version speex decoder? Would be pleased to have the answers ASAP. Thanks in advance and in anticipation of the reply. Regards, Sharan

Try version 1.2beta1, which might have better project files.> 2.

So versions don't matter unless you're using *really* old encoders/decoders (version 1.0 was released in March 2003). Jean-Marc
