Discover a New Dimension of Sound with Neuzeit Instruments Quasar: The Binaural 3D Audio Mixer for Eurorack

Neuzeit Instruments Quasar is a creative and versatile tool that brings an exciting new dimension to the world of Eurorack modules: binaural 3D audio. Quasar is a two-channel audio mixer that uses advanced binaural algorithms to create spatial 3D sound with dynamic positioning in height, angle, and distance. You can seamlessly move sounds around your head and change the angle, height, and distance in real-time, creating a unique and immersive experience for the listener.

Quasar features two mono inputs and a stereo output with two single jacks and a headphone stereo jack, 24-bit 48kHz inputs and outputs, and 32-bit internal processing. The module also includes two CV inputs with flexible routing options, internal LFOs with flexible routing, and different ear types to choose from, providing adjustable 3D effects that fit the processed audio signal to personal needs.

The module is intuitive and easy to use, featuring two large endless encoders with aluminum knobs and RGB LED rings for setting and displaying parameters, an OLED display for navigation, and a flat menu structure that keeps a hands-on feeling. You can also create user presets that can be flexibly recalled.

Quasar creates a 3D sound image by binaural audio processing, and you can virtually place and move two positions, named Quasar 1 and Quasar 2, at any angle, height, and distance around your head. Room reverb can be added as a further aid to distance perception. The audio signals at input 1 and input 2 can be flexibly routed to either or both positions via an internal matrix mixer. The coordinates of the positions can be set manually or be modulated by internal LFOs or external CVs.

Quasar features two CV inputs which can be flexibly routed to any target inside the module, enabling a very flexible design of auditory 3D-scenes. Internal LFOs can also be used to add dynamic movement and to create spectacular three-dimensional scenes, with a variety of standard and advanced waveforms that can be routed to the position coordinates.

Quasar's reverb can improve distance estimation and also be used to create impressive ambient stereo soundscapes. The module also offers digital high and low pass filters for all inputs, which decide which frequency bands go to which position. Additionally, you can also route the audio to the center position, which takes the input signal and distributes it equally to the left and right ears without further processing, preserving the mono-compatibility.

As spatial hearing is a psychoacoustic effect that everyone perceives slightly differently, Quasar offers several Ear Types to choose from, allowing you to adjust the intensity of the 3D effect to personal needs and fit the processed audio signal.

Overall, Neuzeit Instruments Quasar is an exciting and innovative module that offers a unique way of experiencing sound in the Eurorack world. With its large aluminum knobs, LED rings, rubber potentiometers, and mechanically solid components, Quasar is a fun and creative tool to use, inviting users to explore new and creative sonic possibilities.

Example Usage

If you're new to 3D audio mixers, Neuzeit Instruments Quasar provides an excellent starting point. Start by connecting two mono signals to the module's input, and then plug in your headphones to the stereo output jack. You can then use the module's controls to move sounds around your head, changing the angle, height, and distance in real time. Explore the different ear types available to find the one that matches your psychoacoustic preferences. Lastly, try experimenting with internal LFOs and room reverb for dynamic movement and improved distance perception.

An intermediate-level usage example of the Neuzeit Instruments Quasar module is to create a dynamic 3D scene of a helicopter flying overhead. Connect a sample of a helicopter sound to input 1 and a low-frequency sine wave to input 2. Set Quasar 1 at the front-right position and Quasar 2 at the back-left position. Use an external CV to modulate the height and distance of both positions to simulate the helicopter taking off and landing at different distances. Use an internal LFO to modulate the angle of the positions to create a spinning effect. Apply room reverb to enhance the sense of distance. Save the scene as a user preset to access it easily in the future. Use a pair of headphones for the best directional hearing experience, and choose an Ear Type that fits your personal hearing preference.

Further Thoughts

Use Quasar to create a breathtakingly realistic ambient soundscape with dynamic movement. Route two different CV signals to the Quasar 1 and Quasar 2 positions and use the internal LFOs to control the movement of the sound sources. Apply the room reverb for added authenticity and adjust the Ear Type settings to personalize the 3D effect. Save the scene as a user preset for later use and recall it at any time with the module's intuitive interface.
