Hi Jonathan,

Thank you very much for your feedback.
Sorry for the late reply, the virus situation in the last two weeks has
been quite disruptive.

I have just created a merge request on GitLab,
which contains a `fakenews` directory in the `externals` with a `vinyl~`
object in it.
This effect is currently implemented as a low shelf filter, which serves as
a starting point to imitate the "warm" sound that a vinyl produces.
To get to the ideal sound, there are still a couple of things to do:
1.  Add the "crackling" sound of vinyl
2.  Use a high shelf filter to decrease the amplitude of some high
frequency component

In addition to that, I am also planning to
1.  Implement a `digital~` object with a high shelf filter to boost the
high frequency components to implement a "cold" sound of digital music, as
suggested by you.
2.  Test the filters thoroughly.
3.  Document these objects clearly in the `*-help.pd` patches.

I would much appreciate any feedback.

To get feedback from "someone", I guess you are referring to the purr data

I hope you are staying safe and healthy.
