right settings for highest quality
Hi
I am trying to evaluate the quality of the CELT codec by using the 0.8.0
testcelt tool to encode and decode the input.
I want to test different bitrates and selected the below parameters for 64,
96, 128, 196, 256kB:
./celt-0.8.0/libcelt/testcelt.exe 44100 2 256 46 $1.sw $1-64kb.sw
./celt-0.8.0/libcelt/testcelt.exe 44100 2 192 46 $1.sw $1-96kb.sw
./celt-0.8.0/libcelt/testcelt.exe 44100 2 128

can I create command line versions of the newer test releases?
Hi,
I am a newbe here, so I hope I am not asking something crazy. I was looking on the Celt downloads and I noticed that the latest command line builds were for version 0.6. I know it is still early in development, and that the devs probably don't have time for developing CL versions for everything. since I know nothing about sourcecode and whatnot, I was wondering if there was a fairly simple

Endianess Switch?
Jean-Marc,
It appears that since testcelt reads a WAVE file from disck and passes the
data directly to celt_encode, so that celt_encode's "in" buffer must be
expecting little-endian formatted packets. Is this correct? Is there
endiness switch somewhere?
Thx

CELT Output audio file does not run
Dear all,
Iam a student pursuing MSc degree in computer science at the University of
Babylon,Iraq. My project is about the CELT. I have chosen version 0.3.2 of the
software, lcc compiler, windows xp environment. One of my current problems is
that when I execute the?testcelt program tool,?the output audio file can not be
payed. Could you help me, please? I have tried some media players ,like

FIXED_POINT
Hi,
I've recently successful built and run CELT under Windows using
"testcelt.c" example file. Since I'm about to port it on a embedded
platform i activated the FIXED_POINT #define.
I included fixed_generic.h and without other changes to the code i tried
to encode and decode the same file i previously used.
The output though is completely saturated i.e. it jumps from -32768 to

memory violation in mode_create() !
?
There seems to be a memory violation when calling celt_mode_create(48000, 240).
?
The function compute_pulse_cache() calls celt_alloc (the second one,
bits=celt_alloc()) in order to allocate 343 byte, but it is using about 872
bytes at that location, which will be deleted by the following allocations.
?
In this case the following encoder call crashes at first run.

Cleanup/build improvement for opus
Hello all,
after FOMS I decided to take a look at the opus library and I found
that I could improve a bit the build system and cleanup the code a
little bit.
Most of the changes to the code has been suggested by my two tools
cowstats and missingstatic (part of the ruby-elf gem if you care).

[Flac-users] Should I use 11 Khz or 22 Khz
Chuck,
I'm doing a very similar project. I'm not an audio expert, but here's my take on the subject. 22KHz will take more space, but it is higher quality, and would probably be better if you ever decide to put them on CD (44.1KHz, stereo is the required format for CD Audio).
There was a noticeable difference in the two when I tried recording at 11KHz vs 22KHz; I ended up just

ADPCM 4-bit, 6 kHz
I found some posts regarding this issue dating of September 2003, but no
real answer.
The ADPCM format supported by Asterisk (the .vox files) is 4-bit, 8 kHz. I
need 4-bit, 6 kHz, which is also a widespread Dialogic format, to help
migration.
Is there an existing format/codec for this? If not, can I make myself a
shared object in /usr/lib/asterisk/modules? Is this easy??? :-(
Thanks,

Quotation request: 12 KHz signal generation for billing purposes.
Could anyone quote a price for the following project.
We should be able to generate a specific (say 12Khz) signal at certain
intervals (calculated using a price/rate table on a mySQL database) DURING
an ongoing conversation.
The conversation is to be marked (start and end) with specific signals as
well. This is a requirement for special hotel applications where a device
counts the signals to

SNOM, g722 and 16 kHz audio
Hi there,
I've been playing with a SNOM 360 and 190 trying to get them talk to each
other using g722 with 16 kHz. However all I see in the SIP log codec
negotiation is "g722/8000" which makes me believe that this is only a 8
kHz link (and that's what it sounds like).
Anyone every managed to establish a 16 kHz wideband call between SNOM
phones?
Cheers, Philipp

Encoding audio sampled at 44.1 khz?
Hi Peter,
Have you considered resampling the raw 44.1kHz stereo source files using
a program such as http://audacity.sourceforge.net/, say to 16kHz mono or
32kHz mono, and then using the wideband or ultrawideband speex modes to
encode the result?
Alternatively, if you want to programmatically do the resampling
yourself, you could try the new resampling API in the svn head of speex,
or the GPL

88.2 Khz files
Hi,
Does anyone know of a technical reason why FLAC cannot support 88.2 Khz files? I have a reason to uses this rate since it is easy to perform quality conversions from 24 bit 88.1 Khz master files (stored as flac files) to 16 bit 44.1 khz files for CD mastering purposes. I suppose I could Kludge the wav files so that they were half speed wav files at 44.1 khz and then hand the over to Flac, but

encoding 22 kHz
hi,
is it possible to encode 16 bit, 22 kHz, stereo/mono WAV files to FLAC files
or could there be a problem with the low frequency 22 kHz (lower then CD
quality)?
PS: I'm a FLAC beginner
thx

Change 48 khz sample rate limit
Hi!, I wondering if It's possible to change 48khz sample rate limit?,
I'm Planing to encode with OGG codec a audio signal but I need that
OGG Encoder works with 192khz of sample rate.
It's Possible?
Any Suggestions?

Change 48 khz sample rate limit
You asked in the Vorbis list, but your text only mentions OGG. The
codec commonly used in OGG containers that is limited to 48 khz is
Opus. Maybe you are trying to use the wrong codec (i.e. Opus instead
of Vorbis)?
Using a 44.1 khz wav file, I was able to encode a 192 khz ogg-vorbis
file with the following command:
$ oggenc --resample 192000 input.wav
Of course, if your original material is

resampling to 48 kHz
One thing that has always bothered me about the ogg
format is the distortion of high frequency sounds -
even at data rates as high 128 and 160 kbps. I find
the best way around this is to resample the wav file
to 48 kHz (using SoundForge 6.0) before encoding
(using CDex) to ogg. It takes a while, and adds a lot
of extra wear and tear on my drive, but what a
difference! The result is an 80k ogg file

R GUI considerations (was: R, Wine, and multi-threadedness)
Hello,
Following a discussion initiated on r-devel, that mentions SciViews-R
and other GUIs issues for R, I would like to make comments (and would be
happy if these comments would initiate interesting initiatives).
A big, big problem with SciViews-R is that a part of it is written in
Visual Basic 6, a M$$$$ language, not supported any more, buggy, non
transposable to other platforms, etc,
