Hi All, I am trying to use VAD opption of speex encode on STM32F4 chip. But when I use *speex_preprocess_run *function, It allways return 1. Anyone can show me the problem? And please, give me an example about using VAD. Thanks in advance, Regards, Nhan. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipe...

Hi all, I have been trying to impelement echo cancellation on STM32F4 Discovery board (having ARM based uC).In my project, I simply initialized the echo_state by speex_echo_state_init() by using frame_size 160, filter_length 800 (at 8kHz Sampling rate.) Then, I simply used speex_echo_cancellation() function in where i am getting sound. However, I have recently realis...

Hi all, I have been trying to implement speex echo cancellation algorithm on STM32F4 Discovery board; however, I could not make it work properly. I tried synchronous, asynchronous way of to do that and the only thing I heard was "cazzsdaos?eo?hodg etc" :) I try to use empty array for all parameters in the cancellation function, but the result is always the same ("c...

...nus speex functions for this? Best Regards, KAHYA PS: Sorry for my bad english.

Hello I am a university student and I have just started to usespeex newly, I am implementing this codec on STM32F4 and I use speex library. Ihave a problem with VAD, can anybody help me? I want to know which parameters Ishould tune in my code (using speex library)? Which function should be called?I want to record a voice on SD card and I want to use this algorithm to detectsilent periods to save my SD capacity....

I'd like to compress a 32 kHz 16-bit mono using an STM32F4 microcontroller. My plan is to capture from 500-1000 ms of data, compress, and send the result over a UART. I have the arm-none-eabi tools installed on MacOS. I used homebrew to install autoconf, automake, and libtool. autogen.sh succeeded and I was able to create my makefiles using the following:...

Also, unsure why encode is taking less > time than decode... Last month a user posted some benchmarks on a STM32F4, which is a the same core as your cc3220 but at 168MHz rather than 80Mhz. Here's the results: http://lists.xiph.org/pipermail/opus/attachments/20180114/a0340dfa/attachment-0012.png Based on that it seems that your decode should take about ~10ms, so it'll be a bit of a squeeze to get full...

Thanks Jean-Marc, I was able to get both encode and decode working the CC3220 device! But for bi-directional communication, I need decode and encode to occur in less time than the frame size I’m sending (20 ms). Currently decode takes 16~22 ms and encode is ~13 ms. What is the best way to try to reduce this time? Also, unsure why encode is taking less time than decode... I've also
