Benchmarks on Pi
I have to admit that I am impressed by your results -- making 1.1 look
slower than 1.0 is by no means an easy task. On the other hand, it's a
great tutorial on how not to use Opus, so for the benefit of everyone,
this is a summary of what we learned in this exercise:
1) When running on ARM, the fixed-point build is usually faster than
floating point. This is true on the majority of ARM archs

Benchmarks on Pi
It might be good to use the (uncompressed) samples on the opus page, as a common starting point?

Benchmarks on Pi
Cliff,
Yes it would be good, but very hard to get a figure for the quality.
At 6kbps I assume it does not bother trying to figure what mode to use as
at that rate it can only use SILK. When I run some other bitrates it may
get a bit slower trying to decide whether it is voice or music.
I started with low bit rate because I am only really interested in Voice
and very low bit rate.

Opus Major Version Benchmarks on Raspberry Pi
I wanted to roughly benchmark how the different version of libopus
performed at each complexity level for a 6kbit/s output opus file. This was
conducted on a Raspberry Pi so it is a constant hardware platform. This was
done on an early Pi so only 256MB RAM but it was never used up so should
not make a difference.
I compiled the three final versions of each major release of libopus so
that was

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.

Benchmarks on Pi
Hi All,
What would be interesting would be a plot of complexity versus subjective or
object audio quality.
I've not had a chance to look at the new analysis code in 1.1 so maybe in
the case of a 6kbps compression you could clarify what decisions would it be
making that would justify the extra complexity?
Best Regards

Benchmarks on Pi
I have run a few more test at different bitrates and 1.1 is looking even
worse in terms of speed compared to previous versions.
I have shared a google sheet which has the raw data and charts for 6,16 and
32 kbps. Unfortunately you cannot show proper error bars on Google sheets
but the standard deviation is in the data if you want to look. You can see
that the profile for 1.1 is a lot different

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:

1.1 Much slower on Raspberry Pi
Hi Stuart,
you are compressing it at 6kbit/s. Then, then SILK mode is probability used
and the Silk mode is much faster than CELT. Do you also some figures at
64kbit/s?
It is strange that Opus 1.1 got slower in the Silk mode - may the
speech/voice selection adds some overhead. I would be interested in seeing
the performance of the 64 kbit/s in both Opus 1.0 and Opus 1.1.

Three-dimensional (3D) movement using 'R'
Hi Everyone,
I have a question regarding the construction of 3D graphs in 'R', BUT
these graphs also need to illustrate movement (with time) of the
prostate gland (using radiological techniques). I am not sure how to do
this in 'R' although I'm sure there is some way of doing it.
Below, I have copied and pasted some of the data with which I'm working
on. The data

Error installing package sna
Dear R-users,
These days, I have been struggling to install the package sna on my Ubuntu
8.04 laptop. My R version is currently R 2.7.2. And I had no trouble
installing any other packages (including network).
However when I run 'install.packages("sna")', compilation of C codes is ok,
but a syntax error is reported when building help pages and sna does not
want to install.

Created rpm from wine 0.9.14 does not install - conflict with desktop-file-utils-0.10-9
Hi
I downl;oaded the source distribution of wine 0.9.14 and compiled it as
described in the readme file. I now created an rpm with checkinstall.
My problem is that I can not install it, as it tells me that there is a
conflict with the package desktop-file-utils-0.10-9:

It includes 0.9.14
