[Speex-dev] FW: Message to Speex-dev

[Sharanu]

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
