Abstract
An audio signal processing system according to an aspect of the present invention includes an audio signal processing unit configured to select one rendering scheme among a plurality of rendering schemes, based on track information for indicating a reproduction position of an audio signal, and render the audio signal by using the one rendering scheme selected.
Claims14
An audio signal processing device for receiving an input of at least one audio track and performing a rendering process of calculating output signals to be output to a plurality of audio output devices, the audio signal processing device comprising:
- a processor configured to select one rendering scheme among a plurality of rendering schemes for audio signals of each of the at least one audio track or split tracks of each of the at least one audio track, and perform rendering processing on the audio signals, wherein
- rendering processable ranges are defined in a plurality of the rendering schemes respectively, each of the rendering processable ranges being indicative of a range within which a sound image can be arranged, and
- the processor selects the one rendering scheme, based on sound image locations assigned to the audio signals and the rendering processable ranges.
An audio signal processing device for receiving an input of at least one audio track and performing a rendering process of calculating output signals to be output to a plurality of audio output devices, the audio signal processing device comprising:
- a processor configured to select one rendering scheme among a plurality of rendering schemes for audio signals of each of the at least one audio track or split tracks of each of the at least one audio track, and perform rendering processing on the audio signals, wherein
- the processor selects the one rendering scheme for the audio signals of each of the at least one audio track or each of the split tracks, based on a distribution of the sound image locations assigned to the audio signals in a period from a track start to a track end.
An audio signal processing device for receiving an input of at least one audio track and performing a rendering process of calculating output signals to be output to a plurality of audio output devices, the audio signal processing device comprising:
- a processor configured to select one rendering scheme among a plurality of rendering schemes for audio signals of each of the at least one audio track or split tracks of each of the at least one audio track, and perform rendering processing on the audio signals, wherein
- the processor selects the one rendering scheme for the audio signals of each of the at least one audio track or each of the split tracks, based on a maximum reproduction sound pressure of the audio signals.
