1.1 Much slower on Raspberry Pi
Resampling to 48khz speeds them both up but the disparity is about the same: 2.609 to 3.69.

1.1 Much slower on Raspberry Pi
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

1.1 Much slower on Raspberry Pi
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",

PC Benchmarks
I thought I would run the same benchmarks on my PC that I have been running on my Pi. This is a very different beast as it is a i7-4770 with 4 cores (8 with hyperthreading) and 16GB RAM. This is a bit academic as any x86 PC in the last 10 years can encode very quickly and unless you are converting a huge catalogue you will not notice a small change in speed. That being said I wanted to see if
