This near-real-time audio stream originates from a seismometer at Cambridge, MA, USA (Raspberry Shake station R199D). The low-frequency sounds of the solid Earth have been speeded up by a factor of 50× to make them audible. As a result, frequencies have been transposed upward about 6 octaves. Each successive audio program (separated by a brief pause) compresses the last 3 hours into about 4 minutes (exactly 03:36) of listening time.
