[speex-dev] fixed point conversion volunteer (OMG what am I doing?)
Hello Mark: Count me in. I'm an excellent C programmer and I've done assembly coding. Although I've not done float to int conversions, I'll pick it up quickly ... send me an example, please. Also, I direct The Tech Startup Connection here in Silicon Valley, so I have a very large resource pool. Check out <http://www.techstartupconnection.org>www.techstartupconnection.org. <p>>I'm willing to contribute some time to converting speex to fixed point.> >I'm not doing this for a particular product and I will receive nothing but >some warm fuzzy feelings for "giving back to the community". >Consequently, I don't want to do it all myself. > >So ... is anyone else currently working on this? > >Splitting the work into chunks should allow more people to write code when >it's convenient. > >I haven't known about speex for very long (very cool project -- much >needed), so I'm not very familiar with the code yet.

Hello People,
Are there any ongoing efforts to port speex enc/dec
to java? I know there are a couple of things lying about in
jcraft and other sites but they all seem a little half hearted.
I've used jspxdec.zip written by james.lawrence@hellonetwork.com
to knock together a little applet for playing speex files but james'
decoder only deals with a subset of the options.
The applet is on http://www.vivasonic.com/speex/SpeexPlayer.html
and requires the java plugin to work, also if you want to play any files
from your hard disk or from other sites you will need to accept the dummy
certificate I used to sign the jar file.
regards,
Kaveh.
