Yes, the Faust Web IDE can only use float samples for now. We are working on adding double support. > I downloaded the command line tools, but when I run (for example): > faust2max6 -quad MECIfilters5GUI.dsp > > I get Quad is probably not supported correctly yes. But faust2max6 uses -double by default, since Max 6 and later use double samples (see https://github.com/grame-cncm/faust/tree/master-dev/architecture/max-msp) You can try that first. > ERROR : cannot using -single, -double or -quad at the same time > (double might be working, but I am getting a linker error that I still need > to resolve) > > if I run > faust MECIfilters5GUI.dsp -quad > > That works, but I just a dump of C++ files, which I am not sure how to use. > > Likely, it is just because I am not finding the right documentation, so if > you have a pointer that would be appreciated.

The Faust C++ generated code is somewhat agnostic related to sample rate. The architecture code gives the compiled DSP the desired SR at init time. You can always develop a specific architecture file for a special need, or adapt an existing one. > > Thank you again and in advance for your help- > Kind regards, > Mark-David > Stéphane _______________________________________________ Faudiostream-users mailing list Faudiostream-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/faudiostream-users
