How To create Binaural 3D Audio in Eurorack with the Neuzeit Quasar


The latest video from Perfect Circuit features German synthesist Martha Bahr (aka Panic Girl) sharing how she creates binaural 3D audio effects in her Eurorack system using the Neuzeit Quasar .


The Quasar brings 3D spatial audio to the Eurorack world. It is a two-channel audio mixer that uses binaural algorithms. You can seamlessly move sounds around your head, dynamically change the angle, height and distance in real time.




  • 2 mono inputs
  • Stereo output (two single jacks + headphone stereo jack)
  • 2 CV inputs
  • 24Bit 48kHz inputs and outputs, 32Bit internal signal processing
  • Dynamic 3D positioning in three dimensions (height, angle, distance)
  • Room reverb can be applied for better localization
  • Internal LFOs with flexible routing
  • External CVs can be flexibly routed to all parameters, multiple destinations per CV, individual intensity
  • Different 3D transfer functions to choose from
  • Two large endless encoders with aluminum knobs, RGB LED rings for setting and displaying parameters
  • OLED display for navigation and to show which parameter the encoders are currently controlling
  • Flat menu structure, no deep dives neccessary
  • User presets can be flexibly created and recalled
  • Potentiometers for volume control of the three positions Quasar 1, Quasar 2 and Center



Watch the video till the end for a performance demo of the Quasar in action.
