Volcano, Hawaii, USA (infrasound [high band])

This near-real-time audio stream originates from an infrasound array at Volcano, Hawaii, USA (UH Infrasound Network station MENE). The low-frequency sounds of the atmosphere have been speeded up by a factor of 180× to make them audible. As a result, frequencies have been transposed upward by about 7 octaves. Each successive audio program (separated by a brief pause) compresses the last 12 hours into exactly 4 minutes of listening time.
