Opus Major Version Benchmarks on Raspberry Pi
...th the raw numbers and the bash script I used
(though you have to do all the compiling yourself).
Hope this is helpful.

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:

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
