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 enablin...

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...

Hello, i want to create a little program on BF533 EZ KIT Lite and VDSP++ the purpose of this program is to compress an input audio frame with speex then uncompress it to get the audio frame on output of the EZ KIT the input sample rate is 16KHZ and i can't get a lower sample rate with this kit When i use a 160 samples frame and narrow band...

...visibility of what's going on within a small "bare metal" target. But such developers a less likely to integrate speex because it simply doesn't fit. I guess I am one of the few that try to run speex entirely from internal RAM and the fact already forced me to move from BF531 to BF533. BTW, the above exercise in deep philosophy at shallow shores shouldn't be taken too seriously ;) >About the inline assembly, I was under the impression that the syntax >was compatible. Could you tell me what's the problem? If it's just one >bit, you can easily remove the fun...

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 when a new audio //...
