Hi,
The old autotools build system defaults to using single precision floating
point numbers in DSP calculations and buffers (symbol WITH_FLOAT defined in
config.h) but there is an alternative, if the user provides to the "configure"
script the argument "--with-doubles=no", that in despite of logic has the
effect of undefining WITH_FLOAT in config.h, enabling double precision
floating point numbers.
The new CMake build system uses by default double precision floating point
numbers, but there is an option ("-Denable-floats=yes" as a command line
argument) that defines WITH_FLOAT in config.h forcing the usage of single
precision floating point numbers in DSP buffers and calculations.
Double precision real numbers are bigger, and probably have worse performance
than single precision floats, but maybe they can produce better sound in some
circumstances. Floats are probably safer because they have been tested more
deeply, as the ticket #87 has shown.
So, what do you think? leave doubles as default in CMake, or change the
default to floats, like in the old autotools?
Regards,
Pedro
