Universal De Emphasis Calculator
Our research and development team, supported by some international partners, has long dealt with the technical aspects to be taken into consideration in order to correctly replay a 78 rpm record. From the choice of the stylus to the right de-emphasis curve to be applied, whether you opt for a traditional electromechanical reproduction system (i.e. a turntable) or any optical systems, such as VisualAudio, Irene, or Saphir for instance.
On this page, we have decided to disclose the results of so much work, creating and releasing a small web application that can be of help to all those who have in their hands a 78 rpm record to replay.
