CONCEPT FOR AURALISATION USING EARLY REFLECTION PATTERNS Russian patent published in 2025 - IPC H04S7/00 

FIELD: physics.

SUBSTANCE: invention relates to early reflection processing concepts for auralisation. Embodiments relate to an apparatus and methods for rendering audio based on early reflections and to an apparatus and methods for determining an early reflection pattern. Device (100) for determining an early reflection pattern (1) for reproducing sound enables to receive room acoustic parameters (310) that represent an acoustic characteristic of acoustic environment (5), early reflection pattern (1) is determined, which indicates a constellation of early reflection positions. Early reflection pattern (1) is obtained through parameterisation of spiral functions (3, 4) centred at position (10) of the listener using acoustic parameters (310) of the room. Positions of early reflections are arranged using certain spiral functions (3, 4).

EFFECT: generating a sufficiently believable and compelling perception by the listener, which is suitable for all acoustic parameters of the room.
