<DIV><FONT size=2>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. <BR></FONT></DIV>
<DIV><FONT size=2>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 the InitializeSpeex() function.<BR>For example, we set: <BR>
tmp=1;<BR> speex_decoder_ctl(g_pvDec, SPEEX_SET_ENH, &tmp);<BR>
tmp=1;<BR> speex_encoder_ctl(g_pvEnc, SPEEX_SET_VBR, &tmp);<BR>
tmp=8;<BR> speex_encoder_ctl(g_pvEnc, SPEEX_SET_QUALITY,
&tmp);<BR> tmp=3; <BR> speex_encoder_ctl(g_pvEnc,
SPEEX_SET_COMPLEXITY, &tmp);<BR>(the other parameters are preserved as
default.)<BR></FONT></DIV>
<DIV><FONT size=2>Would you like to help me to solve this problem? or send me
some renewed speech codec demoes can work better on BLACKFIN DSP please. <BR>I
also noiticed that somebody met the same problem unsolved, see: <A
