Thanks !<br><br>On this forum is also shown this information :<br><a href="http://lists.xiph.org/pipermail/speex-dev/2009-January/007050.html">http://lists.xiph.org/pipermail/speex-dev/2009-January/007050.html</a><br><br>According to vk's results, it could be possible to run Speex at 4/6 & 8 kbps on a Cortex M-3 at 36 MHz ... so not excluding the EFM32 ...<br>

On ST forums there is someone that states it has done an optimized<br>
port of the library that run Speex at 4Kbps (ST port is only 8Kbps).<br>
<br>
Take a look here (hoping that the link works):<br>
