...ic instead of voice as well and share the charts here. If anyone wants I can share the OpenOffice spreadsheet with the raw numbers and the bash script I used (though you have to do all the compiling yourself). Hope this is helpful.

...mittedly quite an old ARM architecture, the promised speed boost for 1.1 on ARM is not present. Unless you compare old complexity 10 with new complexity 5 which I understand may be equivalent. So it is just something to be aware of.

Resampling to 48khz speeds them both up but the disparity is about the same: 2.609 to 3.69.

Christian, I will give 64kbit/s a try and post the figures. My own project is voice only and requires low bitrate so was hoping that it was just the way I was compiling and not an actual regression in speed for SILK. The raspberry PI is quite a cheap and handy reference platform though the ARM side is fairly underpowered but has a great GPU. It also has no audio in which is a pain for playing

I have just started trying Opus with a view to using it in a project. I am interested in embedded hardware and tried it on the Raspberry Pi using the raspbian distro. The version of libopus in the repos is 0.9.14. I installed this and tried encoding 2 minutes of speech from a librevox recording. It managed this at a respectable pace for complexity 10: Skipping chunk of type "LIST",
