...y eliminating some of them, but I have a feeling that generic mechanism for picking only those modes needed (either through conditional compilation or may be even with configuration perl script) would be simple than specific DISABLE_VOCODER. Another potential saving could be achieved by replacing speex_warning, speex_notification and speex_error with user-modifiable defines. The existing DISABLE_WARNING/ OVERRIDE_SPEEX_WARNING method is not efficient in reducing the code footprint because the majority of the overhead happens in the points of invocation of the speex_warning rather than in the function...

...e I'll need to go further into the guts of speex to do this. I do, however, see some lines in nb_celp.c/nb_decode() that look interesting. I guess I'll play with it. I doubt that it will be terribly clean, though. Jean-Marc: Take a look at line 1195 in nb_celp.c (CVS).

Hi, I got my hands on the LCA 2003 CD today and I tried to listen to it on my powerbook running Linux. Instead of getting speech, I got an earfull of noise! Attempting the same experiment on an i386 with the same CD produced understandable speech. It seems that the output routine in speexdec converts the output data to little endian short format, which is incorrect on the ppc architecture. The

Could you clean the patch and send it back to me so I can apply it? Jean-Marc

Is there any way to access only the narrowband portion of a wideband stream? I'd like to be able to encode the audio only once, but allow members in a conference to have some rough selection of bandwidth, and allow them to move to a lower-bitrate stream if there is a need to do so.

I have been trying to understand how to get the VAD algorithm working. I sent an input stream of all zeros into the preprocessor but still got a return value of 1 indicating that speech was detected. Is this feature not available with the latest release? I thought at the very least it would detect this as silence and return 0 but that does not seem to be the case. Does anyone have any
