Build it with the -mfpmath=sse flag enable. That would help. Or add a denormal protection to it . @211 for (int i=0; i<count; i++) { float S0[2]; float fTemp0 = input0[i]; - S0[0] = fTemp0; + S0[0] = fTemp0 + 1e-20; _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
