Hi Kjetil,
In my own code I tend to exploit the incomparibility of NaN.
Instead of:
if (x < lo) x = lo; if (x > hi) x = hi;
I write:
if (! (x >= lo)) x = lo; if (! (x <= hi)) x = hi;
As any comparison with NaN gives false, the first version will pass NaN through unchanged, but the second version will replace NaN with lo. Behaviour with finite values and +/-Infinity should remain the same as the first version.

Sorry again, that patch was for tabread4~, which should work fine. Trying again:

Not sure what Miller's policy on C standards is, but all other Pd code seems to declare all variables at the start of a block.
int idelsamps; t_sample a, b, c, d, cminusb; if (delsamps < 1.00001f) delsamps = 1.00001f;
