Acoustic surround immersion control system and method
View Patent ↗A method and speaker system that provides a single, user adjustable tool for controlling how and which spatialization parameters are used in a single speaker multi-driver system to enhance the sound stage. The tool creates the desired amount of audio surround effect to enhance the sound stage experience or effects in multiple sound recording mode, such as music or movies. The tool is represented in a scale that runs from ‘−10’ (less immersive) to ‘+10’ (more immersive) is set to taste by the listener and will vary with room acoustics and placement.
1. An audio speaker system comprising:
a speaker having a housing and a plurality of speaker drivers; wherein said speaker drivers are operably associated with an audio signal source and capable of generating audio sound at a plurality of audio frequencies corresponding to a right channel, left channel, center channel and rear channels of an audio signal;
a digital signal processor electrically associated with the speaker drivers and audio signal source, said processor receiving the audio signal from the audio signal source and modifying said audio signal such that the resulting audio signal include changes in the timing of signal transmission, volume level or frequency of the right channel, left channel, center channel or rear channel signals such that the generated audio sound provides psychoacoustic cues corresponding to acoustical characteristics that reproduce the original spatial acoustic experience;
a display associated with said speaker drivers and processor; wherein said display provides an on screen image representation of the acoustical characteristics and wherein such acoustical characteristics may be modified.
2. The audio speaker system of claim 1 further comprising a remote controller, the remote controller is in wireless communication with the system and provides remote access to the on screen image of the display and whereby modification are made to the plurality of acoustical characteristics.
3. The audio speaker system of claim 1 , wherein the speaker housing is a single speaker enclosure.
4. The audio speaker system of claim 1 , wherein the speaker housing is a pair of headphones.
5. The audio speaker system of claim 1 , wherein the psychoacoustic cues are selected from head related transfer function cues, interaural crosstalk cancellation, or audio volume level.
6. The audio speaker system of claim 1 , wherein the display is a television or a smart phone display.
7. A method for changing the acoustical output characteristics of an audio speaker system comprising the steps of:
programming into a memory a plurality of sets of predetermined parameters corresponding to audio signal digital processing and acoustic outputs that generate psychoacoustic cues, said outputs and cues associated with acoustical soundstage characteristics;
graphically representing the set of parameters on a display;
selecting one of said sets of parameter by selecting the corresponding graphical representation of said set of parameters;
receiving an audio signal having at least a right channel, left channel and center channel signal;
processing said audio signal and generating an acoustic output according to the selected set of predetermined parameters.
8. The method claim 7 wherein the set of parameter on a display is graphically represented as a sliding scale.
9. The method of claim 7 wherein the acoustical soundstage characteristics are selected from a group including music or movies.
10. The method of claim 7 wherein the display is a television or smart phone display.
