In recent years there has been increasing interest in making digital transfers of disc sources with a flat phono preamp, applying phono equalization in the digital domain with equalization modules included with digital editing and restoration software. In order to accomplish phono equalization properly in the digital domain, it is essential to apply both frequency and phase responses that are complements of the recording curves. Some older software-based equalization programs failed to provide correct phase response. One popular and affordable restoration program has numerous pre-defined curves identified only by record label, with no information on the turnover frequencies used for those curves, and no provision for separate bass and treble settings. iZotope’s popular RX10 restoration software and Ozone mastering plug-in have analog filter emulations based on Infinite Impulse Response (IIR) minimum-phase digital filters. They precisely duplicate both the frequency and phase responses of analog filters, making them ideal platforms for phono equalization in the digital domain. Appropriate filter parameters make it possible to create extremely precise, independently adjustable bass and treble phono equalization curves.
