Maybe MMX lacks that. I'll check when I have the time.
yes i think the mmx/sse2 code does overwrap. however, i also think that there is a switch to turn that on....wait...no ehm there is only a switch in the [pix_gain] object to turn this on/off: it is [saturate 1/0( though saturation is the logical usage, i would like to provide both ways, for legacy reasons and for freedom of choice. mfa.sdr IOhannes _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
