Symbian port
A couple of things to be noted on the symbian port.
1. the spokn.mmp file is missing window.c, please add that.
2. smallft.c is not required. it has global data that prevents compilation
on symbian.
3. lbr_48k_tabels.c has a global variable called dummy_epic_48k_variable
on line 37. this has to be commneted out too.
4. check that all tables are declared const.
i will shortly post the symbian

Bug with the new preprocessor
Hello,
I have an (Access violation reading location) on line 115 in the fftwrap.c :
out[i] = scale*in[i];
with i = 1193
Only with preprocessor active
Systems : Visual studio 2005, XP, WB 16000 Hz, last svn.
Hope it helps you.

speex encode and speex_bits_write buffer size
Ashhar Farhan a ?crit :
> how many calls can I make to speex_encode_int before calling
> speex_bits_write? Can I stuff 10 frames?
Yes. Even if you put more, it'll just auto-resize the buffer. For 10
frames, it won't even have to resize.

libspeex for other platforms
wouldn't it be a good idea to have the libraray available as a binary for
non-PC platforms like the PocketPC, Symbian and Mac?
i am suggesting this as it will allow the developers to go ahead and
program to an interface while the development continues.
there are builds for symbian, pocket pc and linux already in the tar ball.
putting their binaries on the download section will probably

SPEEX on iPhone ?
Hello Ashhar,
thanks for your reply, but i'm a bit surprised.
1- Does it mean that it is possible to make a Real Time Encoding/Decoding
with SPEEX on iPhone ?
2- What parameters have been used (QUALITY, SAMPLING_RATE, BITRATE) ? and
what kind of CPU load do they measure for that ?
Thanks by advance,
Vincent

SPEEX on iPhone ?
ok, interesting !
Do you know how much CPU it takes for a real time encoding/decoding ? it's
more around 20% or 80% instead ?
Do you know if it works for 44100 Hz / 32kbps / Quality =8 ?
thanks again.
Vincent

bad VAD in preprocessor of version 1.2beta1
Hello, first of all, sorry for the joke in the subject ;-)
I have successfully update the speex library my software was using from
1.1.12 to 1.2beta1 (1.1.13).
It is a VoIP software, where i set preprocessor VAD on and use the
result of speex_preprocess() to determine if there is voice activity.
I must say that it works fine...since i have update to the new version.
Ive been testing, and

Windows Mobile build, memory allocation
I have sent the visual studio project files that compile the speex
client to jean-marc directly (as an attachment), sometime this week, I
will also upload the binary builds of static library files to my site
www.phonestack.com.
I am porting our LTP (lightweight telephony protocol) to some embedded
systems. I require to run speex in an environment that doesn't support
memory allocations. How

Speex realtime encoding/decoding "Real world" usage for Windows Mobile / Symbian device
hi all,
I can claim that our hotfoon service has run millions of mobile voip
minutes using speex on mobile and desktops. it works!
earlier you needed more powerful cpus (until the integer port),
however now the cpus are much faster and the code complexity is much
lower.
my only regret is of not being able to write some demo apps for speex
on win mob. I will surely deliver it in june to settle this

SPEEX on iPhone ?
Why don't you just try it?
From what others have been reporting, it shouldn't take you long to
get it running.
You can use speexenc and speexdec for testing.

FIXED_POINT warns on compute_weighted_codebook
hi,
i am trying to compile a fixed point version of lipspeex on desktop
windows environment. a short reason for the complicated story is that
we need to keep the 'engine' part of our project same across the various
ports of our voip project (blame the pointy haired boss).
now, when i compile with FIXED_POINT defined in the Visual C++ 6.0, i get
these errors:

SPEEX on iPhone ?
I can confirm that it will run in real time on iPhone if you compile
with FIXED_POINT defined; it will also run in real time if you have
FLOATING_POINT defined and disable 'Compile for Thumb' in the target's
build settings in xcode. Wideband works too.

Palm OS port
hello all,
At my workplace, our colleague Mukesh has just completed a port of
speex 1.2.1 to Palm OS. He had to write a couple of mathlib functions,
but the trunk remains unchanged.
It works quite well, I was wondering if there will be any interest in
this port in the distribution.

Just getting noise
I'm only doing one frame using speex_encode_int greatly simplifies my
code I'm not sure why the sample I was working off of was converting
the shorts to floats then calling the other encode/decode methods.
Based off of your suggestions I tried the following but I get the same
result.
virtual Enigma::u8* Encode(Enigma::u8* inputBuffer,size_t inputSize,
size_t& outputSize)

is it ok to call speex_encode_int after speex_bits_write?
I'm reliably getting a corrupt stream when I do a certain encoding and
decoding test.
I've pegged it down to this: encoding some frames, calling
speex_bits_write() and then encoding another frame produces a corrupt
stream.
My question is, is this a speex bug or incorrect API use?
I can provide a test case (currently in python, will translate to c if
needed).
Thanks,
Micky

Quick question
Hi,
I am developing my own file format and I have a question about the
standard encode method:
speex_encode_int(st, raw, &bits);
nbBytes = speex_bits_write(&bits, s+1, 255);
My question is : Will nbBytes ever be 0 ? (even with an empty
frame of all 0's passed to speex_encode_int) In other words is it
possible for the encoder to return
a compressed bit stream that is 0

SPEEX on iPhone ?
hello,
i 've already used SPEEX in a protoype of voip application (on VC 6) and i
must says that it works well, the sound is good, and the object works well
with multi-instances.
But now i'm wondering if it's possible to port the SPEEX encoder (and
decoder process) on iPhone ? Does someone tried to do that ?
Do you think it is possible or completly over the capabilities of the ARM

Comparison
i have been working on a voip client that goes head-to-head with skype in
technological terms. for this, we used speex wide-band codec. without the
denoiser or the pre-processor, i find that speex quality at 16 khz
sampling, 16-bit samples (mono) to be clearly superior to anything that
skype offers.
even though, at the moment, i am not using packet loss compensation, i
find that speex is
