Abstract
Described are apparatus for generating and/or processing audio signals. One apparatus includes: a first stage for obtaining an audio signal; a second stage for modifying the audio signal based on one or more control signals for shaping sound represented by the audio signal; a third stage for generating spatial metadata related to the modified audio signal, based at least in part on the one or more control signals; and an output stage for outputting the modified audio signal together with the generated spatial metadata. Also described are corresponding methods, as well as corresponding programs and computer-readable storage media.
Claims25
An apparatus for generating or processing audio signals, the apparatus comprising:
- a first module for obtaining an audio signal;
- a second module for modifying the audio signal based on one or more control signals configured for shaping sound represented by the audio signal;
- a third module for generating, with an electronic processor, spatial metadata related to the modified audio signal, based at least in part on the one or more control signals;
- and
- an output module for outputting the modified audio signal together with the generated spatial metadata.
A method of generating or processing audio signals, the method comprising:
- obtaining an audio signal;
- modifying the audio signal based on one or more control signals configured for shaping sound represented by the audio signal;
- generating, with an electronic processor, spatial metadata related to the modified audio signal, based at least in part on the one or more control signals;
- and
- outputting the modified audio signal together with the generated spatial metadata.
