Hi,
Yes, it happens only with speex and lpc1015. I was wondering if
these problems are related with float point operations.
I tried compiling libspeex with --enable-fixed-point configure option,
but I could hear only some peace of my voice in the test_speex
program, as I reported in previous messages. Enabling this
configure option is not sufficient for me. I need more optimizations
if I want to use speex.
The lpc1015 encoder makes a expensive float-point operation
(read_16bit_samples). I think the lpc10-1.5 directory has a lot of float point
operation. Is there any easy way to change them to fixed point??
