Grallion2, but it’s not free … https://youtu.be/u-iyuK_mmXs?t=335
HelmetRadio plugin (free) does lo-fi, but no pitch-shifting or glitchiness.

IMO the free (limited) demo version of AudioThing’s “speakers” is worth the effort of download … https://youtu.be/-B-WS1xN0I0?t=215 : it has glitch & interference effects.
