First: Using an equalizer, kill all frequencies below
~600 and above
~2k. Use a graphic EQ for this. (The two values are just examples, you
can play with both frequencies to get the desired sound you're looking
for.)
Second: get a recording of the inside blank track that comes after the
last song of a noisy record. Loop this noise and mix it over top of
the song once you've done the band pass filter from step one.
That's a bit drastic for vinyl - more like an acoustically recorded
78rpm from about 1920. Those were pressed on shellac, not vinyl.
The priciple's about the same, though - add a few random background
ticks and clicks, a bit of white noise as many vinyl discs had tape
noise from the master, possibly a bit of distortion on peaks if you want
it to sound like a worn record/stylus, and also some gentle frequency
variation at 0.5 Hz (for 33 1/3 rpm) to simulate a less-than perfect
turntable or warped record.
I'm sure it can be done with Linux tools...
