samples, but a number of newer software systems use float. On modern
host cpus it's just as fast and you don't have to write your filter code
for every combination of sample depth, signedness and endianness.
Speex was re-written to use ints/fixed point to efficiency on embedded
cpus with no fpu, of course, so it's better to use the _int versions if
