Abstract
The present application concerns early reflection processing concepts for auralization. Embodiments relate to apparatuses and methods for sound rendering considering early reflections and to apparatuses and methods for determining an early reflection pattern.
Claims30
An apparatus for determining an early reflection pattern for sound rendition, configured to
- receive at least one room acoustical parameter which is representative of an acoustical characteristic of an acoustic environment;
- and
- determine an early reflection pattern
- which is indicative of a constellation of early reflection positions,
- by parameterizing one or more spiral functions centered at a listener position, and placing the early reflection positions using the one or more spiral functions.
A method for determining an early reflection pattern for sound rendition, comprising
- receiving at least one room acoustical parameter which is representative of an acoustical characteristic of an acoustic environment;
- and
- determining an early reflection pattern
- which is indicative of a constellation of early reflection positions,
- by parameterizing one or more spiral functions centered at a listener position, and placing the early reflection positions using the one or more spiral functions.
A non-transitory digital storage medium having stored thereon a computer program for performing a method for determining an early reflection pattern for sound rendition, comprising
- receiving at least one room acoustical parameter which is representative of an acoustical characteristic of an acoustic environment;
- and
- determining an early reflection pattern
- which is indicative of a constellation of early reflection positions,
- by parameterizing one or more spiral functions centered at a listener position, and placing the early reflection positions using the one or more spiral functions,
- when the computer program is run by a computer.
