You can go further with resampling, lfos on sample playback. Some examples are far from subtle and of topic, but they can be used for that purpose. The principle is to use 2 recorders recording their playback alternatively.
From technique below (with much more subtle settings ), I think you can get lots of tape artifacts…adding very slight lfo on pitch too…
