converts speex (spx) audio format to mp3 or other common audio format.
Having a slow connection I would like to try and save bandwidth by downloading audio books in speex format as they are a much smaller file size. The only programs that I have come across are shareware or commercial to convert spx to mp3. Does anyone know of a free / open source program??
Printer-friendly version
I used the speex windows builds of speexdec.exe and created the following batch file. (All files resided in same directory for ease of use.)
for %%A in (*.spx) do (
speexdec "%%A" %%A.wav
)
WAV files are easier to convert to as all codecs should be on your computer already. All the MP3 conversions I tried did not work because I was not calling an MP3 encoder like LAME.
So, I simply will throw all the newly created .WAV files into AudioGrabber and convert to MP3.
It took me 3 hours to assemble all this info. ;)

I like Format Factory.
A few thoughts...
I haven't tested it but this sounds like it should work: lets you convert between Ogg Speex and Wave PCM. to convert to your favorite audio format.
Ogg Media Creator
Then use a tool like SUPER
The 3CX Phone System may also be worth looking into to see if it can do what you want.
Another possibility is asking for help in the http://www.xiph.org/ forum.
I'm not aware of any freeware program that will handle this conversion. However if you go the SPX site you can find on their software page some of the plug-ins that have been written for SPX. I see there is one for WinAmp and that might be worth investigating.
