I found this from Izotope, a well respected company making professional audio editing software. This is about Ozone 7. I have been using their RX series (currently using RX3 Advanced) in my record and tape ripping project over the past five+ years. Larry
Analog tape’s most desirable qualities at your fingertips for digital music production.
The Vintage Tape module in Ozone 7 Advanced is modeled to emulate the clean and flat Studer A810 tape machine — known for its excellent frequency response — that was commonly used in classic mastering studios. Take advantage of that analog tone for masters that sound more musical with added dimension, fatness, and depth.
The controls in Vintage Tape let you access the qualities of tape that are most relevant for mastering and adjust them to get the right results for your track.
• Input Drive: A lower Input Drive setting offers less saturation and a higher setting will incorporate more of the gentle distortion that magnetic tape is treasured for.
• Bias and Speed Controls: A negative bias value will push more energy at the higher frequencies, while a positive bias value will attenuate higher frequencies.
• Odd and Even Harmonics: Mix the authentic odd harmonic saturation of a calibrated mastering machine with even harmonics to taste.
• Emphasis Controls: Add a gentle peak in the rich areas, get a high-end shimmer, or dial in a gentle roll-off.
Learn how to get started with the Vintage Tape module.
