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

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.

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.
Cheers,
Dave

SPEEX on iPhone ?
vincent,
it should work out of the box. real time speex should work on the
iphone as it has a really fast arm cpu (and speex works in realtime on
even the 201mhz arm cpus).
while compiling, remember to define the fixed-support support and you
are all set. narrow band (8khz) and 8kbps bitrate will work very well.
while you are at it, pse send the xcode project file to include in the tarball.

thanks for your reply,
could you explain why 44.1kHz is *not* recommended with SPEEX ?

SPEEX on iPhone ?
vincent,
someone in our team did compile it on iphone. he didn'y any particular
problems. the arm specific optimizations are not necessary given
iphone's fast cpu.
just add all the speex sources to xcode's project pane and compile it.

Did I ever mention that 44.1kHz is *not* recommended. Usually, 16 kHz is
best, although 32 kHz can be good in *some* cases. In any case, you'll
need to listen

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

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

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.

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

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

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:

Playing captured speex frames
Hi,
Searched far and wide for a solution to this problem but couldn't find anything.
I'm debugging a VoIP application that uses Speex and need to playback
the raw speex frames to verify the quality. Wireshark helped me save
the RTP payloads into a file but unfortunately, the speexdec utility
seems to be wanting a valid header at the start of the file without
which it reports an error.
