Hello, I'm using speex provided with the Blackfin SDK on a BF533 EZ-KIT LITE In this version of speex, the program is used in wide band with a sampling rate of 16KHZ But i want to use it in narrow band mode with a sampling rate of 8KHZ In AudDriverFuncs_AD1836.c file, i see that the supported sample rate are 48000, 24000 and 16000 --> I don't understand because in the readme file it

So developers that integrate speex tend to have plenty of RAM and once one has plenty of RAM he could install biggish OS. And between biggish OSes for Blackfin the most popular choice is uCLinux. And ucLinux works best with gnu tools. Something

I am looking into using speex for a decode only application on the blackfin. Encoding would be done elsewhere with voice phrases loaded into FLASH. Code space is a premium in the blackfin app, and mips to a certain extent 1) The source code seems to be codec-centric with encode and decode in many of the same files. Does anyone have any hints on what can be removed easily that is used only

Hello, I'm new on DSP and i want to implant speex echo canceller on the Blackfin DSK version of speex to work on the BF533 EZ-KIT LITE But i can perform the echo canceller to work This is my code, so if somebody can tell me where i'm wrong //----------------------------------------------------------------------------- // CallBackFunction() - Gets called by the audio pseudo-driver

Hi, I'm trying to encode a stereo speex file on the blackfin without much luck. This is a standalone application with no OS using the speex library provided in the blackfin multimedia sdk. I believe this library was ported to run using Visual DSP++ by Jean-Marc (may be wrong). I have mono encoding working fine, to add stereo encoding I just added a call to speex_encode_stereo_int()

I bought a ADSP-BF533-EZkit-LITE V2.1 to develop a speech codec application using SPEEX. I have tested SpeexEcho project from both BlackfinSDK-Rel201 and BlackfinSDK-Rel310. When disabling SPEEX processing, i.e. using PASS-THROUGH mode, the output voice is ok, which is exactly as the input voice. However, when enabling SPEEX processing, the output is bad, no matter how to set the parameters in

Hello, I'w trying to encode a wave file using speex beta1.2 and cygwin i installed speex following the manual instructions but when i want to encode the file using speexenc -w francais.wav test.spx the software answer that only PCM encoding is supported Is somebody can explain me what's wrong?

Hi there. I am having a little trouble understanding the frame sizes chosen by the codec. testenc_uwb.c from the speex-1.0 source distribution has a framesize of 640 hardcoded and makes use of this value exclusively. However, a mode query on the actual codec returns 320 as a framesize for this mode. int tmp; speex_mode_query(&speex_uwb_mode, SPEEX_MODE_FRAME_SIZE, &tmp);

Hi Jean-Marc, As I told you, bank is a reserved keyword in Analog Devices compiler for Blackfin architecture. So we need to change the variables named bank to something else. Here's a patch that changes bank to bnk in the 3 concerned files. (Hope the format is OK) About my previous problems with the Blackfin: -> strange block repetition that could be cancelled by the AEC I was busy

Same here Michael and the PocketPC version seems unaudible with any codec; early days trying that though.

hi, i am using AVTransmit3.java for transmitting audio, how can i implement JSpeex or speex for compression and encoding. please give me some idea about this. shankar.s speex-dev-request@xiph.org wrote: Send Speex-dev mailing list submissions to speex-dev@xiph.org To subscribe or unsubscribe via the World Wide Web, visit http://lists.xiph.org/mailman/listinfo/speex-dev or, via email, send a
