[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. I did code fixed >point replacements for a couple of the functions in filters.c, but I >haven't put much thought into how to organize these into the mainstream. > >Has anyone already done any analysis on the dynamic range at various >points of the processing?

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. <p><p>--- >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.
