Abstract
A rendering method of an object-based audio signal and an apparatus for performing the same are provided. The rendering method of an object-based audio signal includes obtaining a rendered audio signal, performing clipping prevention on the rendered audio signal using a first limiter, mixing a signal output by the first limiter using a mixer, and performing clipping prevention on the mixed signal using a second limiter.
Claims9
A rendering method of an object-based audio signal, the rendering method comprising:
- obtaining a rendered audio signal;
- performing clipping prevention on the rendered audio signal using a first limiter;
- mixing a signal output by the first limiter using a mixer;
- and
- performing clipping prevention on the mixed signal using a second limiter,
- wherein the first limiter comprises a plurality of limiters, and
- wherein each of the plurality of limiters is allocated to each audio object.
An apparatus for rendering an object-based audio signal, the apparatus comprising:
- a memory comprising instructions;
- and
- a processor electrically connected to the memory and configured to execute the instructions,
- wherein the processor performs a plurality of operations when the instructions are executed by the processor, and
- wherein the plurality of operations further comprises:
- obtaining a rendered audio signal;
- performing clipping prevention on the rendered audio signal using a first limiter;
- mixing a signal output by the first limiter using a mixer;
- and
- performing clipping prevention on the mixed signal using a second limiter,
- wherein the first limiter comprises a plurality of limiters, and
- wherein each of the plurality of limiters is allocated to each audio object.
