192 kHz sound collection of two antique german printing machines.
We got our hands on two functioning vintage Letterpresses: The motorized “Original Heidelberger Tiegel” (built in 1969 by Heidelberg Schnellpressen AG) and the pedal-driven “Boston Pedal Tiegel” (built in 1901 by Emil Kahle Maschinenfabrik). We captured these two unique printing machines in 192 kHz stereo from different angles using a range of microphones (Sennheiser MKH 8040 ORTF, Neumann TLM 103 ORTF, Barcus Berry Stereo Contact Mic). The 15 recordings are on average 4 minutes long each and include idle, run, stop and different running speeds.
