LDC spectrogram

The LDC logo includes a spectrogram, a visual representation of an acoustic signal. The horizontal dimension corresponds to time – reading from left to right – and the vertical dimension corresponds to the frequency, or pitch, of the sound. Acoustic intensity is represented by the darkness of the image.

The spectrogram represents the voice of Jack Godfrey, the Consortium’s first Executive Director, saying the letters L-D-C. It has remained a part of our logo since LDC’s founding in 1992.
