Digital Remastering
Technical faults in the majority of her original gramophone recordings—especially variations in recording speed, which raised or lowered the apparent pitch of her voice, misrepresented the "light and shade" of her phrasing, interpretation and delivery. They altered the apparent key of her performances (sometimes raised or lowered by as much as a semitone.) The fact that the "centre hole" in some of the master recordings had not been in the true middle of the master disc meant that there were wide variations in tone, pitch, key and phrasing, as commercially released records revolved around the spindle.
Given those historic limitations, the current digitally remastered versions of her work deliver significant, very positive differences in the sound quality of Smith's performances. Some critics believe that the American Columbia Records compact disc releases are somewhat inferior to subsequent transfers made by the late John R.T. Davies for Frog Records.
