Opus decoding performance on ARM devices
...e9a009ca, added a bunch of more defines to
my compile options, and assembled & linked in
armopts.s,celt_pitch_xcorr_arm.s.
Performance jumped up from about 4.8 Mb/s to 5.3 Mb/s on the same device,
so it is improvement. Not sure what other tweaks there would be to try,
but if it could match the tremolo decoder, we could probably throw that
out entirely which would be very nice.
Thanks!

Opus decoding performance on ARM devices
...erformance of various audio decoders,
particularly for ARM devices (Cortex A8 / A9). The context is audio
playback in a game engine, and thus decoding performance is of particular
interest.
Looking at Opus versus Vorbis on a Cortex A9 smartphone, the numbers look
approximately like this:
Vorbis (tremolo decoder)
9.3 Mb PCM/s
Opus (libopus 1.1)
4.8 Mb PCM/s
The Opus audio is encoded approximately 120 kbps (and the vorbis file has
higher bitrate). On ARM devices this far I get Opus decoded at about half
the rate (and on x86 they are about on par).
Should I be able to squeeze more performance out...

choppy sound with playback, background, etc... but not with musiconhold
Hello,
I have an asterisk 1.2.18 working fine, the only problem is that all
applications that play audio, sound like "tremolo" or "vibrato", but
musiconhold plays fine.
The same audio file (wav, mp3, ...) works fine with Musiconhold()
but not with Playback() or Background()...
If I move app_playback.so from this system to another asterisk,
playback works fine...
Do you know what is happening and how c...

New repo and moving tremor discussion here
All,
I've consolidated our various svn branches of the fixed-point vorbis
decoder (known as tremor or tremolo) into a single git repository,
hoping that it facilitates review and merging of the various trees. In
particular, android has a branch of Robin Watts' Tremolo code
(arm-optimized tremor-lowmem) which I don't think anyone on the Xiph
side has looked at.
I used git-svn to import the history,...

recent Vorbis, sound quality problems
Hello all,
I'm having some problems with the sound quality of recent Vorbis.
There is some kind of metallic echo/tremolo effect in the lower
frequencies. This is on my iMac; haven't seen this problem on x86.
If you need a sample, I can put one up somewhere, or mail it to
someone with a good ftp server, preferably.
It could be caused by the iMac sound system doing surround sound,
(Dolby Spatializer or something);...

Optimised ARM Ogg/Theora/Vorbis decoder
This is a note to announce the availability of "Ogg Theorarm", an
optimised ARM implementation of decoding libraries for the Theora
video code, and Vorbis audio codec from xiph.org.
Full details of this code release can be found at
<http://www.wss.co.uk/pinknoise/theorarm>, but highlights include:
* Full speed playback of a 320x240x25fps clip with a 48kHz stereo
audio track on
