The Dr. Scientist Spectrum Analyzer is a device which reads audio information and displays it in seven frequency bands, from 63 Hz to 16 kHz, represented by LEDs. It reads information from any source that can be plugged into it — a computer, a guitar, a synth, a cellphone — or it can read the sound around it through a built-in microphone. Musicians hungry for information can see their music in realtime, represented by light.

  • Power Requirements: 9 V DC @ 250 mA, 2.1 mm plug, center positive
  • Input Impedance: 10 mΩ tap-off 'looking' at audio signal
