HA! Just when I was getting ready to drop myself from this list, along comes a ham radio question! Shoving digital voice down a 100 Hz pipe would be mighty darned tough/impossible. N0YMV has a good suggestion. Try those WSJT modes. They use narrow bandwidth and are fun to play with. There are documented instances where moon-bounce QSOs have been completed with these modes. No, it's

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

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

Great!!! Do not hesitate to let me know if it works ok for you! Cheers, Raphael 2018-04-16 22:59 GMT+02:00 David Willmore <davidwillmore at gmail.com>: > That's great news!

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 don't mind at all. I imagine there are more people like me out there who have been following your work, but haven't said anything. I agree that a series of pages explaining how things work may lead to more contributions. At the very least it would lead to more people being better educated on how wavelets work in image compression. But, this is your project, if you don't have the

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

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

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

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

Dear Sir, Could you please forward this e-mail to your engineering department. I am a ham radio person who wants to transmit from the Earth to the moon and back to the Earth by phone not by Morris code. This will be a very weak signal. I need an extra 13.8 dB of gain. Could you please help me distribute the attached paper to someone who could take this project into the next level? Please reply

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

Jean-Marc, > I've got no problem cross-compiling with gcc for Blackfin. See the > README.blackfin file. Thank you for your help, Jean-Marc. I get no further with that than I did before, I'm afraid.

Dave, I have been interested in some of the same questions that you have been asking. A while back I asked a person at VLSI ( http://www.vlsi.fi/ ) in Finland if they had a product that might work. The exchange of email is included below. In summary, the answer was probably no, but maybe in the future. The VS1005 chip he mentions does not seem to have appeared yet. I currently have a pair

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
