Hi Jean-Marc, will you include these optimizations for minimal ram usage in the main version? Maybe if Peter sends a Patch...

Sounds like you did most of what you needed to do. Using a coverage analysis tool might help you remove bits of code here and there (e.g. unused _ctl() cases), but the main part is done. About the preprocessor, there are some of the state variables that could instead be allocated on the stack, but that's about as far as you can shrink things.

Hi, I am using 1.2beta2 on a C5416 doing narrowband in the decode function I am having a problem with the execution of my program vectoring off to random interrupts that are not used. I have tracked down the error to the highpass function called in nb_decode -very close to the end of the function-context: it is called here: ln 1719 for me if (st->highpass_enabled) highpass(out,

Hi, So I got a crash on the following code: k1=SUBMODE(lpc_enh_k1); k2=SUBMODE(lpc_enh_k2); which in the newer codebase is: bw_lpc(SUBMODE(lpc_enh_k1), st->interp_qlpc, awk1, st->lpcSize); bw_lpc(SUBMODE(lpc_enh_k2), st->interp_qlpc, awk2, st->lpcSize); I am not sure if the newer code will have the same issue but the following check is

Hi, I am trying to implement Speex in freeRtos on LPC2138 (ARM7 core), to record about 10sec of voice. I like to compress the data by using Speex, because of the limitation of RAM (32KB). I have read that the speex encoder and decoder need less than 6KB RAM. "The fixed-point narrowband encoder+decoder memory use has been cut by more than half, making it possible to fit both in less than 6 kB

Hello everyone, I'm finally beginning to use Speex for a project. As expected, the implementation so far has been very easy and I am thrilled with the capabilities and flexibility of Speex, especially the new features in 1.1. My efforts so far have resulted in a couple of questions: 1) I was interested in fetching the default quality setting for narrowband:

Hi, Is there any way to determine frame size in bits or bytes of encoded frame in WB mode for given quality? That is I need to know how many bits encoded frame will occupy in RTP packet. I see SPEEX_SUBMODE_BITS_PER_FRAME request, but it works like this only for NB mode, and for WB mode it return size of WB "subframe" (?) only. -- Regards, Alexander Chemeris. SIPez LLC. SIP VoIP, IM

I am hoping to use Speex for a embedded project using Philips Arm processor (50 mips) 512kb flash 32kb ram. I found in the manual that decode takes about 0.5 mips so I should have enough processing power and I compiled the lib and it seems to take less then 64K so the only issue is memory usage. I have been testing the speex decode on windows looking at the stack usage and how much is malloc.

I would like to hear from some one who has ecb, multiple modes with ruby mode + html mode, rails mode all working together and playing well. I had ecb working with Ruby syntax highlighting. That was a no-brainer since I just had to apt-get them on my Debian Sarge box.

Hi everyone, Just to let you know that version 1.2beta3 is out. The main change is the split into libspeex and libspeexdsp. Basically, libspeex keeps the codec (just like it was for 1.0.x) and libspeexdsp has all the new components. Other changes include a new jitter buffer algorithm and resampler improvements/fixes. This is also the first release where libspeex can be built without any floating

Hi all, I am a newbie here and just started using speex in our lab. During compiling my voice application with windows-compiled version provided today, I am getting "unresolved external symbol _speex_wb_mode". I am probably missing some setting with VS6.0 linker... (I am a bit new to windows too) If anyone could point it out, I would appreciate it. - Tim -----Original Message-----

Greetings to All! Now I am trying to run speex on TI DSP... I need only coder+decoder+AEC. Bitrate 8000bps. Building with floating point support. What can i do, to reduce RAM consumption? I mean very serious RAM optimisations. Deleting not used structure fields, etc... May be I can do something with alloc... Help me to determine that it is possible to throw out. What is best result(in RAM

Happy new year all! I have had a few issues with this sort of stuff- you could adjust NB_ENC_STACK or SB_ENC_STACK (which ever you may be fiddling with) and see if the problem goes away- could be the allocation for the vorbis psy tables takes up more space than the current stack size allows (not sure how allocated? Could be your settings for supporting alloca/etc. are set different than jm,

Hi Jean Marc and List, So I have started finally fiddling around with Ultra-wideband mode. It appears to be very similar in operation to Wide mode, except that when peering into the packet structure it looks like (and these are kind of questions as much as statements here): 1. update rate 0 is not used in UWB- only 1-4? 2. The total bits used for each UWB update rate seem to be as follows:
