[PD] tabread4~ interpolation revisited

having asked my students to compose pieces in Pd using audio data in
tables and reading them via tabread4~ my ears are still slightly
bleeding from the interpolation artefacts audible in almost every second
composition. Surely, everyone likes to slow down playback and I think it
should be possible without too many audible artifacts in Pd.
There is this legendary discussion on this list
after Cyrille kindly posted about his tabread4c~ external. He also
pointed out more elaborate interpolation schemes such as in
At that time a lot of list members agreed that it might be great to
switch interpolation algorithms in tabread4~ with an argument or
message to the object. As far as I can tell no additional interpolation
got implemented until today. Am I correct here?
The issue got briefly revisited two years later in 2010
and raised by me again in 2015
after which I switched to supercollider for the specific project I was
working on at that time as it performed better at slow playback.
What could be a possible way to get slow playback from tables with less
artifacts? (I am tempted to add "in 2019") ;)
Thank you for all ideas and comments!
