Torsten Ahl (German National Library, Music Archive) and Tom Lorenz (Cube-Tec) will give a joint presentation on Tuesday, September 24 at 2pm CEST.
The topic of the presentation will be: Playback speed identification for early shellac records
Summary:
This presentation addresses determining the correct playback speed of early shellac records. Digitising records from the early 1900s requires expertise in tuning, recording mechanisms, playback equipment, acoustic reproduction physics, and historical knowledge of pitch and musical performance. Choosing the right equalisation curve, playback speed, and needle is crucial for obtaining an authentic signal. While digital level corrections are possible, losses from incorrect signal extraction are irreversible.
QUADRIGA products ensure accurate digitisation and documentation. In collaboration with the Music Archive at the German National Library (DNB), a customised solution was developed to meticulously store all parameters in a database compliant with the AES Standard for audio metadata (AES57).
The presentation includes historical audio examples and will be jointly held by Torsten Ahl, audio engineer at the Music Archive of the German National Library, and the system manufacturer, who will explain the technical layout of the solution.
