Hi there
I am familiar with audio engineering etc but somewhat new to pd.
I am in the process of building a sample-playback engine for sound effects.
Can someone enlighten me as to the meaning of 4-point polynomial interpolation as it is used in [tabread4~]?
A link with the info would be appreciated if it is written somewhere.

Thanks in advance
Dan

bring it on, I'd enlist
Miller's book references to Benson's no?

Wow, thanks

they taught us about linear interpolation (w/regards to oversampling) in school, this is good some familiar ground to springboard from.
This application of the polynomial basically allows a very smooth curve using few points? It sounds like the four points are measured from sample-values at any given point in time, just to be clear is this correct?
does it measure between 2 samples and generate 4 points? or are there 4 sample values that provide the points for the polynomial curve?

Now why does the help file for [tabread4~] add 4 samples to "ensure the usefulness of the 4 point polynomial"?

I am really sorry for burdening you ob1, but you sound like you know what you're talking about!
Plus your tutorials are nifty

AFAIK Digidesign's ASIO is sketchy at best.
It's kinda like their business model (their software only really works with their hardware)
I have a 001 for use in PT but I have had problems using it in Logic and with PD.
I just tried it now and it's seemingly frozen!
