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... -- Anahata anahata@xxxxxxxxxxxxxx Tel: 01638 720444 http://www.treewind.co.uk Mob: 07976 263827
