Hello Miller and everyone on the list!
i have finally got around testing pd compiled to use double precision floats.. what i did was this: pulled the sources from miller's git repo, in fact i didn't realise there was a master tree like this! (if i understand it correct it's the current version repository? the version that i can see in Help->About is reported to be 0.42.5 or may be it's .42.5+ ? please correct me on that ..) so i just used `env CFLAGS="-pipe -O2 -march=athlon64 -DPD_FLOATTYPE=double' ./configure` CFLAGS="-pipe -O2 -march=athlon64" is what i always use ..tought all versions of pd i have compiled before were compiled with this CFLAGS. then `make all` whent fine, but failed to compile sigmund~, that's ok as haven't used sigmund~ yet ..)) then i ran pd and tryied the testtone.pd ..and that's what was weired - it output noise+sine ..hm maybe to do with conversion ..i use RME Hammerfall card .. so there is conversion heppening somewhere .. ok, made another patch, basica [osc~ 200]--[dac~ 1] and that gave DC into the soundcard. using number-[osc~] WORKED and number-[vline~]-[osc~] DID NOT..(( cannot tell if that was a pure sine for 100%, but somewhere most likely pure :) so trying to use a phasor~ seems to be failing too .. has anyone else tested this propertly? as Miller says in CHANGES.txt: " 0.42.0 changed definition of t_float, t_sample, t_floatarg so that they can be set via #defines (PD_FLOATTYPE, etc). " ..hm what does "etc" mean?? maybe i need to define something extra? or [osc~] is all we got working with doubles so far?? well, i checked again ..and it's actually not that near to a sinewave ..it's got some harmonics ..hm i can test anything else ..but there is a general issue to be resolved. can anyone help? it would be very nice to get this working ..hopefully 64bit DAC's are not to far from the general public market :) oh, i forgot to give some details: gcc (Gentoo 4.3.4 p1.1, pie-10.1.5) 4.3.4 so basically i am on gentoo, it's a current stable branch ..sort of but i think it doesn't matter really..it's to do with general porting i reckon! _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
