Did you ever want to get that old vinyl record sound on a recording? It's pretty hard to do manually, since you have to simulate everything from scratchiness to electrical noise to record warping. There is a plugin that will do all of that for you and more, and and the best part is that it's free!
I'm talking about iZotope's excellent Vinyl plugin - the ultimate lo-fi weapon. The plugin will return your tracks to a previous era quickly and with ease, and once again, it's free!
Vinyl provides controls to inject mechanical noise, record wear, electrical noise, dust, scratch, and warp, as well as simulating the era of the recording (1930, '50, '70, '80 and 2000) and the speed of the record (33, 45 and 78 RPM). There's even a unique Spin Down feature that simulates the sound of slowly stopping a record, as well as a stereo to mono switch.
A few years ago I was mixing a song that was a newer version of 1940's blues song, when the artist asked me to "make it more realistic." Vinyl was inserted into the stereo buss, and before you knew it, you'd swear we were back there listening on an old record player.
To get Vinyl, go to iZotope's website. Did I say that it's FREE.
