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?

Hi, Do you think that Speex could run in real time on the new EFM32 ultra-low consumption Cortex-M3 MCU (180 ?A/MHz) (NB 8KHz - Quality 4 - complexity 1 / same as STM32F103 Speex lib.) ? Its max speed is 32 MHz (about 40 MIPs). Thanks. Regards, Nicolas -------------- next part -------------- An HTML attachment was scrubbed...

I am using ST micro's STM32F103 chip with their AN2812 development code. It uses a PWM output, resulting in low-quality sound. Can I just use a scaled version of the PWM to drive a DAC? (i.e. is the output linear, or is there shaping to make the PWM output work?) Any feedback, links or pointers would be greatly appreciated. D...

Dear all, I am trying to use the Speex library pre-processor, I only need the VAD and Echo Canceller. I am using a STM32F103 processor, but I am using a tiny OS and it doesn't allow to use malloc. Is there a version of the library that will work without the need of using malloc? Obviously I will use all the time the same parameters, like 8kHz sampling rate, 160 frame... I will appreciate any help or idea that you...

Hello everyone, For a private project I would like to make a new Internet Intercom device (for my kids and me). At the moment I use a separate DSP with Ogg/Vorbis (VS1053) but I like a challenge ;-) Is a eg. ST32F10x (cortex m3) or a new ST32F40x (cortex m4) powerful enough to do encoding and decoding ? Any existing projects to learn from? Thanks for your time, Edwin van den Oetelaar

...#39;t need malloc at all. Just create a byte array like: unsigned char buffer[160]; And use &buffer[0] as pointer in speex functions?
