With the help of volunteers our team cleans, cataloged and digitized 78 rpm gramophone- and early vinyl records. After the clearing of copyrights, free works are available inside our media pool and Wikimedia Commons (CC0 Project, PD Project).

In order do not further damage grammophone- and vinyl records with needles, since 2010 we digitize with an ELP laser turntable (LT-2XA). All discs are carefully washed by hand before the digitization with a Keith Monks Dual-RCM. For the equalizing we are using three different phono preamplifiers. This means that the audio signals can be processed in the best possible quality by taking the correct equalizer setting. Acoustic and electrical recordings before 1925 had no cutting characteristics. Smaller labels only began to standardize their recordings in the mid-of the 1930s. Before the introduction of the RIAA equalization in 1955 there was no standardization. There was wild growth.
