Abstract
In one embodiment, a system for providing three-dimensional (3D) immersive sound is provided. The system includes a loudspeaker and at least one controller. The loudspeaker transmits an audio output signal in a listening environment. The at least one controller is programmed to store a plurality of directional bands with each directional band being defined by a narrowband frequency interval and to store at least psychoacoustic scale including a sub-band for each directional band. The at least one controller is further programmed to determine an energy for the sub-band and generate a loudspeaker driving signal based at least on the energy for the sub-band to drive the loudspeaker to transmit the audio output signal.
Claims18
A system for providing three-dimensional (3D) immersive sound, the system comprising:
- a loudspeaker for transmitting an audio output signal in a listening environment;
- and
- at least one controller being programmed to:
- receive an input audio signal;
- store a plurality of Blauert directional bands associated with the input audio signal with each Blauert directional band being defined by a narrowband frequency interval;
- store at least one psychoacoustic scale including at least one sub-band for each Blauert directional band;
- determine an energy for each sub-band in the Blauert directional bands;
- and
- generate a loudspeaker driving signal based at least on the energy for the sub-band to drive the loudspeaker to transmit the audio output signal.
A computer-program product embodied in a non-transitory computer read-able medium that is programmed for providing three-dimensional (3D) immersive sound, the computer-program product comprising instructions and being executable by at least one controller for:
- receiving an input audio signal;
- storing a plurality of Blauert directional bands with each Blauert directional band being defined by a narrowband frequency interval;
- storing at least one psychoacoustic scale including at least one sub-band for each Blauert directional band;
- determining an energy for each sub-band for each Blauert directional band;
- and
- generating a loudspeaker driving signal based at least on the energy for each sub-band to drive a loudspeaker to transmit an audio output signal in a listening environment.
A method for providing three-dimensional (3D) immersive sound, the method comprising:
- receiving an input audio signal;
- storing a plurality of Blauert directional bands with each Blauert directional band being defined by a narrowband frequency interval;
- storing at least one psychoacoustic scale including at least one sub-band for each Blauert directional band;
- determining an energy for each sub-band for each Blauert directional band;
- and
- generating a loudspeaker driving signal based at least on the energy for each sub-band to drive a loudspeaker to transmit an audio output signal in a listening environment.
