Here's a Winamp plugin that makes all your cds sound like vinyl records:
Here's the Winamp staff review:
To all you wax fiends... this is for you
Wow...this is a slick dsp plug-in... basically, you can now experience the entire aural history of the vinyl medium thru the use of one nice, shiny and sexy interface. Seriously... there is even a 'year' knob that automatically filters your songs to what the quality of vinyl sounded like in that particular era. The sliders give you access to scratches, dust, warp, noise, etc.... so, you can properly pretend to wear your mp3's out like they were your parent's, or grandparent's even, record collection. Comes with some nifty presets...and as stated before, an ultra sexy interface. This basically rocks. Some of you digital kids or youngins of the CD era may see no point to it...but, for all you vinyl fans out there... you'll know what time it is. Also, this can come in very handy as a quick, real time filter for music producers. One suggestion... it would be nice to have the ability to save your own presets.
