Hallo!
Thanks for all the answers !
it helps, but adding a small DC bias (i.e. adding a
very very very small
constant number to all sample data) works even better.
What do you mean with "works even better"? If we assume that denormal
handling is supported by hardware (like in pentium4 + etc.), isn't this
unnecessary ?
BTW: adding just a small DC bias won't work if I have IIR high pass like
structure, or am I wrong ?
if you app is going to be GPL'ed, feel free to
grab libs/pbd/fpu.cc from
the ardour source code.
Thanks!
LG
