Hi Jean, This is my last attempt at trying to use speex for a project we are working on. I have contacted you before, but i have had no joy what so ever trying to find a working example in c++ that shows how to add a header to a raw speex file, so that it an be played using windows. If you do know of a working example can you please supply a link. As this is a commercial project maybe you could

All, I don't know if this is widely known, but it appears that Microchip has just released a library to perform speex compression/decompression on a dsPIC processor. The library is available under their license, so I can only assume that it is a reimplementation of the algo and not a port. Does anyone know otherwise? Cheers, David

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

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

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?

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

bobby, the speex files cannot be played by "Windows" (I assume you mean the media player) natively. speex codec will have to be supported as a playload type. to do that, you have to install a Speex ACM. take a look at http://www.free-codecs.com/download/Speex_Voice_ACM_Codec.htm once you have it installed, just open the windows recorder from

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

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.

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

Those can be

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

Are there any ports of Ogg decoder to dsPIC processors ? Thanks don

Hi all, Here's an interesting (for me, at least!) problem I came across: I have a correlation matrix, let's say with 6 variables, A to F, as column headings and the same 6 as row headings. The matrix is filled with correlation coefficients. Therefore, the diagonal is all 1's, and each of the two triangles formed by the diagonal has the same 15 correlation coefficients. I need to

Hello Cesar I'm using Speex on a PPC2002 and PPC2003 with no problems. For tune-up remember to define the FIXED_POINT macro in Project->Settings in eVC. With this setting you ought to be able to at least decode in realtime while using debug-mode. Kind regards Bjoern D.

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
