Hello! The question is: "Does Speex support multiple channels?" Speex is reported to encode only mono and stereo signals. But I found 'nb_channel' defined in <speex_header.h> among the Public Attributes. Does this mean that it is also possible to store more than two channels in one single speex-file? Maybe it will be possible in the next future...? TIA -- Mch --- >8

...me to G711. But when I use Speex UltraWideBand the Asterisk don't convert it. Then I need in my Asterisk Channel Source include the Speex Library in resample this frame in 32KHz to 8KHz.

Hello, some misc. cleanup patches for speexdsp, nothing big I'm not sure about how to submit patches, so this is a test balloon :) ultimately, I'd like to fix the FIXED_POINT issue, see http://lists.xiph.org/pipermail/speex-dev/2013-December/008465.html currently, I think the only way to find out how speexdsp has been compiled is to resample some bytes and observe the output; which is
