FIELD: data processing.
SUBSTANCE: present invention describes techniques for synthesizing or processing sound with outputting spatial metadata. Described is a device for generating and/or processing audio signals. One device includes: a first stage for receiving an audio signal; a second stage for modifying the audio signal based on the one or more control signals to shape the sound represented by the audio signal; a third stage for generating spatial metadata associated with 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. In addition, corresponding methods, as well as corresponding programs and computer-readable data media are described.
EFFECT: providing a spatial signal processing process which is not separated from the sound generation process, which enables to reduce time and avoid an additional stage of editing spatial metadata in order to enable generation operations for audio signals.
