Attempting to shrink speex: Are these functions necessary?
Hi,
I am using speex 1.2beta2 on a narrowband 16-bit, 8khz system that has
a severe program space problem and will not fit speex in its normal
operation. In an attempt to shrink speex I placed a breakpoint in every
function and ran a decode and encode and removed the breakpoints that I
hit. in the functions that had a breakpoint that I didn't hit I
commented out those functions (as well as

Attempting to shrink speex: Are these functions necessary?
for the bits init I am using speex_bits_set_bit_buffer and I don't use
the write to or read from because the data is already in the buffer I am
reading from and I am writing to the final buffer so I don't need to
move arrays around.
what part is the vocoder part of the decode?
Thanks for your help!

Attempting to shrink speex: Are these functions necessary?
I'm glad to hear that my data size can be shrunk considerably, however I do not know the minimum values that I would set the static arrays to be. I hate to be a bother but could you tell me the minimum values for these arrays/structures in the state structure? Thanks!

Speex: getting started
Hello!
I'm an Italian student in computer engineering (University "Federico II" of
Naples) and I have to write my graduation thesis in the field of signal
processing. My teacher (Prof. Giovanni Poggi
http://www.diet.unina.it/giovanni.poggi/) has published a research about
multiple description vector quantizers by means of the self organizing maps,
applying his idea to the images and

11kbps narrowband on a 24bit DSP
Hi,
I am using speex 1.2beta2 on a 24bit DSP that has a severe program and
data space limitations. I am only interested in the speex decoder for
11kbps narrowband implementation.
I am using the following parameters and structures
160, /*frameSize*/
40, /*subframeSize*/
10, /*lpcSize*/
17, /*pitchStart*/
144, /*pitchEnd*/

[PATCH] Blackfin: cleanup astat/cc/hardware loop asm clobbers
Most asm statements clobber ASTAT bits (shifts, maxes, etc...) but do
declare the register as clobbered. Same thing with CC in a few places.
Some places make an attempt at clobbering some hardware loop registers,
but it's very incomplete compared with how many asm statements actually
use hardware loops.

GCC/ELF Visibility patch
Hi,
I've attached a patch against SVN r14645 which adds GCC visibility
information to all symbols exported from libspeex.so and libspeexdsp.so.
It includes a configure.ac change to test that both the compiler flags and
__attribute__((visibility)) works, and if so will
#define EXPORT __attribute__((visibility("default")))
and if not

Denoiser level and AEC problem
Hello,
The denoiser was good with a car noise or a raod noise before the r11739.
But for some situation, the actual version is perfect. That's why I think
that if we can adjust the agressivity of the denoiser, we can respond to all
of the situations. Maybe two parameters should be enough : high or low.
For the AEC, I have to test with older versions because it's another person

Denoiser level and AEC problem
Hello,
Is it possible to adjust the level of the denoiser ?
In an old beta, before you change the aggressiveness of the denoiser, it
works very well with the noise of a car, a road etc... but not now.
The AEC too works very well in a old beta, but now, I think there is a
problem... I have tested it with the same sound card (WB 16000).
In any case, your project is the best VOIP library in this

cpu utilization across speex versions
Kemal,
It sounds like you are doing something wrong. I strongly recommend that you
profile your application to see exactly where the CPU time is being spent.
AMD happens to have a nice profiler called CodeAnalyst that they give away
for free. And it's plenty usable on Intel CPUs as well.

Saving iproute2
Thank you Bert, and Wichert.
I know I can put my iproute2 commands in /etc/rc.local. Is there any other
place I can save my commands?
I just want know so I do not have to retype all of the command on reboot.
Thx again

In cb_search, we iterate nb_subvect times over a codebook, finding
nb_subvect codebook entries to quantize the excitation signal. After
finding these nb_subvect codebook entries, they're written into the stream:

creating series of vectors
Dear All,
I am pretty new to R and thus my question may sound silly.
Is there a way to automatically generate a series of separate vectors
(so not arranged in a matrix), without typing and changing every time
the values, and store them as separate *xlsx file, where the "*" is
replaced by the name of the vector itself?
What i would like to create is a total of 12 vectors,

probably heap corruption detection
Hi,
So I see in:
split_cb_shape_sign_unquant
this call is going wrong:
ind[i] = speex_bits_unpack_unsigned(bits, params->shape_bits);
ind as a way negative number- basically this should return bet.
0-255 or somesuch right?
So seems like I need to reset speex at this point if
if (ind[i] > 256) like the note says. So I guess my question is
is this range still valid?
also what is the
