What about Control Panel?
I have a no-windows Wine configuration.
What happens if I install an application that a.o. adds a module to the
Windows Control Panel? Is there a fake Control Panel for this?

Patches for adding 120 ms encoding
Hi Felica,
yes, this is the only reason to have larger frames is on bandwidth limited links having a gross (physical) bit rates of 10kbps per channel.
Decades ago I calculated with figure (for AMR-NB but the same holds for Opus).

Channel Mapping Family for Ambisonics
Hi,
Ambisonics are good for the recording but what is about the playback?
In addition to an Ambisonic channel mapping, isn't it worthwhile to think about
some object based audio coding, too?
But then again, that would be much more work than just adding a new channel
mapping.

Simple code dosn't work
I think you have a syntactical error on the line thats throwing the
error, you state:
> j.even?should be true #throws an error on j == 2, j == 4
should this line not read as:
j.even?.should be true

Channel Mapping Family for Ambisonics
Hello,
We (Google) have been experimenting with configuration and adjustments to
CELT-only Opus that give good results for compressing ambisonic audio
signals [1]. Based on our results so far, we would like to use Opus to
encode spatial audio. We hope to make it easy/possible to use libopus with
other common tools and software modules (ffmpeg/libav in particular).
Based on my reading of the

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

Word and ppt viewers work with Wine???
Installation of the Microsoft Word viewer (97/2000) and Powerpoint viewer
fail in the second dialog of the installation wizard.
I'm using a Wine configuration (latest Codeweavers) without any original
Windows DLLs.
Does anyone have a working config with these two apps?

ODG (Objective Difference Grade) scores for Opus Encoder using PQEvalAudio Tool

Hi Rhishi,
PQevalaudio is very unreliable and buggy. I have compared to PEAQ and - as a

ODG (Objective Difference Grade) scores for Opus Encoder using PQEvalAudio Tool
Hi,
I checked the ODG (Objective Difference Grade) scores for a few reference vectors using the PQEvalAudio Tool and found that some of them show ODG scores as high as -3.5
If we look at the range as described in the link below, it looks unacceptable.

Am I missing something or are these scores valid?

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:

Question about the identification header
Hi,
I'm writing a little API in java that read/write ogg's comments (in the
comment header), as well as reading the information header. All the
"read" part is done and is working well, but I am having a little
problem while coding the "write" part of the API.

[ANNOUNCE] Finally released a first beta ... =)
Hi,
Maybe you remember, I needed help for writing a little java api for
editing ogg comments' tags. I just have released on sourceforge the code
I wrote for my need, for the case somebody would need it.
The standalone version contains the standalone API binaries, and the
bundle version contains the sources and a little GUI for testing the
API. I would have liked the code to be cleaner,

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.
