Hi, I am running speex wideband for speech. While doing that I am getting Hissing sound during silence. If you want I can give you input and output files.

I was browsing through Microchips' website and came upon their Speex library. They are charging for it and looks like it is also not open source. http://www.embeddedstar.com/press/content/2005/6/embedded18391.html scroll down to the paragraph about pricing. - farhan

Hmmm.... it's a shame.... what are the minimum requirements for Fixed Point Speex?

Hello! I'm new to the list, so first I'd like to say hi to everybody! Is there somebody interested in helping with porting Speex on dsPIC series of Microchip's microcontrollers? I was looking at 30F6014A with 144 kB of flash and 8 kB of ram, fixed point DSP core and capable of 30 MIPS. If only one narrowband rate was selected and everything unnecessary stripped down, perhaps it could

Hello, all! I'm trying to see if I can get stock Speex to compile for dsPIC using the current release of the gcc compiler targeted for it. I'm stuck at the very beginning of trying to get past the configure stage. Can anyone who cross-compiles give me an example of how they do that? Cheers, David

Hi I was wondering if someone may help. We are currently using a DSPic to store speex data on a Smart Card. We have now decided to use a PC to playback the speex data. The only problem is our data does not have the Correct header. Do you know if there is an example in C++ that can take a string of speex frames and construct the correct Header so that it can be played back using a pc based

Hi Roberto, The PIC24 family of devices share very little commonality with PIC16 beyond the naming convention. They're a register-based 16-bit architecture, unlike the PIC16. That said, that does mean that LLVM is a much more reasonable fit to target the PIC24 (and dsPIC) than it is for PIC16. Modeling your target files after the MSP430 or Blackfin backend is likely your best bet to get up

Hi, I think this is a very ashamed question I have modified the version of the MSP430, after many problems it compiled, now I want to see is the changes generate what I want, but I don't know how for example with llc -march msp430 foo.ll -o newfoo.ll generates a file for the msp430 and actually did it. but I want to load my changes the --load option is supposed to do that, but the only new

To my knowledge, one can't really work with VoIP without full duplex, and Speex is used quite often for VoIP, so I'll say that people do use Speex in full duplex mode. > I?ll probably change the dspic for a ARM LPC22XX, this is a good idea? Only someone who has had experience

I have been analyzing the implementation for some backend (PIC16, MIPS, SPARC and MSP430) my main problem is that they are so much different, I mean obviously they are describing different architectures, but the file structure is not the same. So it is difficult to get a pattern. I have checked the available documentation files, also the video from Cardoso about how to write a backend for the

Hi Jen-Marc, this news were very interesting because of what I intedd to use speex for... Can you make some personal comments about that? Were you involved or consulted about it? Will it make it's way into the official version? I remember that you commented a long time ago that the DSPIC version was too much of a tour-de-force to make it to the official version, but this is a much nicer

The whole deal of using the new BSD license for libraries like Speex's is to allow companies to release commercial source-closed applications/devices. This to allow wider spread of the formats. Unless they are using the command line tools (e.g. encoder), which are not under BSD but LGPL. In that case, they should provide the source code for all changes they make to the command line tool,

Dear Sirs, I would be interested to hear your views on whether SPEEX could be made to run fast on a DSPIC33 by the following strategy: Make iir_mem16() (for example) purely 16 bit by restricting the number of bits in the signal to say 10 using SATURATE and then making the LPC co-efficients just 6 bits. At present (with standard code) the encode function is taking about 140ms which is seven

Hi, As a way to learn LLVM, I'm trying to write a backend for the Microchip PIC18 8-bit microcontroller. On this device, the hardware stack is very small and is used only for storing function return addresses. A "real" software stack implementation is not very efficient because of the limited instruction set, so for all the non-reentrant functions I've decided to use a similar

I am new to Speex. I plan to try to use a Speex lib package developed for the Microchip dspic30F6014 dsp microcontroller and output the voice audio stream on tcp/ip. Question: Has anyone used the bit stream output from the above and decoded it with real player helix server software? Is there a better server software to attempt? thanks in adance dan gropper _eagle241@aol.com_

Hi David! Many thanks for your very encouraging and kind feedback!!! (Hope you don't mind that I made your post public on the Theora channel). I try to be the more sincere as I can in my posts.Some people suggested me to make demo pages to explain how the codec works step by step, and I realize that it would be good, because certainly it will show that the NHW codec is not that complex and
