Object-Mixing Structure

HOLOPHONIX employs Object-Based Mixing to achieve 3D spatialization.

Unlike traditional channel-based mixing, which relies on fixed speaker assignments, object mixing treats each sound source as an independent object with precise spatial coordinates. For more details, see the Spatialization Guide.

These objects are processed through one of HOLOPHONIX’s advanced spatialization algorithms, providing real-time control over position, movement, and depth. The processing occurs within Spatialization Buses, which connect Virtual Sources to Virtual Speakers.

Each algorithm translates the user-defined object positions into speaker outputs based on the current speaker arrangement, ensuring accurate spatial perception for the audience. Different algorithms handle this process in various ways, , each with its own advantages and trade-offs. This approach ensures a highly flexible and immersive audio experience, seamlessly adapting to different speaker configurations and venue acoustics.

Reverb Routing

HOLOPHONIX integrates a 3D algorithmic reverberation developed by Ircam's STMS Lab, offering control over both acoustic propagation parameters for virtual sources and reverberation simulation settings.

Each spatialization bus is associated with a reverberation bus, that is adapted to the spatialization format. When a virtual source is routed to a spatialization bus, it is automatically routed to the corresponding reverberation bus.

Direct Routing

In some cases, HOLOPHONIX can be used as a simple routing matrix, ensuring audio latency synchronization between spatialized and non-spatialized signals.
