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);
<p>testenc_wb.c from the speex-1.0 source distribution has a framesize
of 320 hardcoded and makes use of this value exclusively.
However, a mode query on the actual codec returns 160 as a framesize
for this mode.
int tmp;
speex_mode_query(&speex_wb_mode, SPEEX_MODE_FRAME_SIZE, &tmp);
How can this discrepancy be explained?
Could anyone shed some light here? ;) thanks.
Christian
