Hi list,
I hope my repeating questions don't annoy anyone. I've sent a similar question a while back to [pd-ot] but with out response, have been thinking over it, found no answer so far.
Although I had never concerned it till recently, I've learned that 4 point interpolation may at times return values less than -1 or greater than 1 even when the 4 reference points are with in that range.
i.e., having a table of [-1 1 1 -1], an index of 1.5 will return 1.25 with [tabread4]
Are there any common practices to avoid unexpected clipping introduced by [tabread4] or [tabosc4~] ?
Further more, under what circumstances (what 4 values referred to) will the returned value exceed the range most?
Thanks in advance..
