Jean-Marc, Yes, fixed-point is enabled (#define FIXED_POINT in config.h). I haven't tried anything lower than 4kbps; like I mentioned, 6kbps sounds fine so it's very strange. The only code I changed to get 4kbps was setting quality to 1 so that is the only difference in my test code between using 4kbps and 6kbps. It seems to be in the encoder. On the ARM side, I encoded a 8Khz 16-bit mono sample in 4kbps...

...i processor, which has an ARM926 processor and a TMS320C64+ DSP in it. I have been using Speex 6kbps (narrowband, quality=2, complexity=1, perceptual_enh=0) on the DSP C64+ side without any issues; the voice sounds very good for such a low bandwidth requirement. However, recently, I tried out the 4kbps mode (changing quality to 1) on the DSP and it sounds robotic; if I ported the same 4kbps code to use on the ARM926 (GPP) side of the DaVinci, it sounds fine (no robotic artifacts). So this leads me to think somehow the Speex code is not working properly for 4kbps (and lower) on the DSP C64+ proce...

...eptance point of view. Technically it is fine. It is exactly doing the job we had expected. It's the long standing wish that everyone wants... More for less. We are just seeking a bit of magic that just may not be there. Ideally finding a codec that can perform tollerably/intelligibly at 2-4Kbps. And still perform quite well for complex speech at 10-12kbps. Just keeping my eyes (ears) out for something that I have never considered before.

Thanks for the reply. We are currently using AMBE (4Kbps) for our Traffic/Weather Channels. If you have ever had a chance to hear the service, you will know that AMBE does not do us well. I understand that 2Kbps is low quality, but any poorer than AMBE? If can get a decent quality for other low bandwidth talk channels, such as about 10-16Kbps and ha...

...t 24 bit resolution. This DSP is named 'Kalimba' and is present in CSR's product: BLUECORE5. I'm very interested if anybody can tell me if porting is possible (in fact if there are sufficient resources) for implementing a real-time encoding-decoding (duplex). I'm interested in 4kbps bitrate. Any help will be greatly appreciated. Thanks, Horia -------------- next part -------------- An HTML attachment was scrubbed...

In fact, on my shelf is running speex using Raisonance Primer2 DK and IAR STM32-SK DK. But I want to save the power consumption of the device runnig speex, and EFM32 seems to be a very good candidate. Also, do yo think that the STM32F103 (Cortex M3 90 MIPS) could be used to run Speex at 4 Kbps in real time? Regards, Nicolas 2010/3/3 Jean-Marc Valin <jean-marc.valin at usherbrooke.ca> >

...44 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 be ported to perform both encryption and decryption in realtime? Microchip adapted Speex at 8 kbps (I was thinking more of 4kbps NB) to run on dsPIC, requiring 19 MIPS for encoding and 3 MIPS for decoding. Supposedly, RAM was the main limitation, requiring 5.4 KB for encoder and 3.2 KB for decoder. They state that full-duplex support is now possible and requires 6.8 KB of RAM, so it looks like it can be done. Unfortunately t...

On ST forums there is someone that states it has done an optimized port of the library that run Speex at 4Kbps (ST port is only 8Kbps). Take a look here (hoping that the link works): https://my.st.com/public/STe2ecommunities/mcu/Lists/ARM%20CortexM3%20STM32/Flat.aspx?RootFolder=https%3a%2f%2fmy%2est%2ecom%2fpublic%2fSTe2ecommunities%2fmcu%2fLists%2fARM%20CortexM3%20STM32%2fSTM32%20Now%20Speaks%20%21%20with...

Based on the chat discussion I would be putting CPU performance numbers for Encoder: Speech, 16KHz, 16-bit mono channel for the following combinations Complexity: 0,1,3,5,9 and Frame Size of 20 and 40ms for Output bit rate of 4Kbps and 8Kbps Any suggestions/critical feedback is most welcome....
