Hi,
not related to the thread on smoother audio in Pd, I am struggling with doing a smooth loop player for data stored in tables.
One building block for this is attached: It is a simple tabread4~ lookup that should loop over a configurable section of a table and play it back with various frequencies. As you'll easily see, I use a
[phasor~] | [*~ loopsize] | [+~ loopstart] | [tabread4~ table]
idiom here. Now I would like to avoid enveloping the rewind sections, so I built an elaborate mechanism to set the loop points as good as possible by hand. Test sections let you load a sample or try to find the smooth loop points inside of a sine-wave table graphically.
Now my problem is, that even when I have found a nice and smooth sounding loop section, as soon as I start to change the frequency played (with the "pd transpose" things), the sound gets very distorted.
I'm puzzled: Shouldn't the tabread4~ interpolate correctly in this case? Any help or explanation is appreciated. (Except anything involving crossfades: I know I could do that and I guess I also know how.)
Ciao
