iZotope has updated its free Vinyl "lo-fi" plug-in to v1.7 which also includes the first versions for Mac OS X (VST, AU, MAS, RTAS, AudioSuite & HTDM).
Vinyl creates an authentic "vinyl" simulation as if the audio were a record being played on a record player. It provides the user with control over parameters ranging from the amount of dust to the year the record player was created.
