RASES · Audio Source Separation & Spatial Sound

Separate every sound.Place it anywhere.

Split stereo audio into vocal and instrument objects in real time,
then place them back in a 3D space around the listener.

Core Technology

Five technologies.
One immersive sound.

Five core technologies that shape where sound sits,
the space it lives in, and the listener who hears it.

  1. 01

    Sound Image Localization

    Places sound precisely at the direction and distance you want — for fixed sources and for sources in motion.

    • Positional / Moving Sound
    • HRTF DB
    • Compact HRTF Synthesis

    Used inPAMSVirtual Multi EarphoneVirtual Multi Speaker

  2. 02

    Virtual Sound Field

    Models the reverberation of concert halls and rooms, so earphones and speakers feel like a wide, open space.

    • Reverberation / Echo
    • RTF Model
    • Room Acoustic Simulation

    Used inrReverbVirtual Multi Earphone

  3. 03

    Listener Position Tracking

    Tracks the listener's head movement in real time, so sounds stay in place even when you turn your head.

    • Head Tracking
    • IMU Sensor
    • Real-time Binaural Rendering

    Used inPAMS360° Spatial Sound

  4. 04

    Crosstalk Cancellation

    Removes the leakage of the left speaker into the right ear, creating wide 3D sound even from two closely spaced speakers.

    • Delayed Inverse Filter
    • Inverse HRTF DB
    • Sound Widening

    Used inVirtual Multi Speaker

  5. 05

    Audio Source Separation

    Separates a mixed track into vocals and instruments in real time, then places each one back into space.

    • Object-based Separation
    • Real-time Streaming
    • OTT · Large Media
