, Description:FIELD OF INVENTION
[0001] The present invention is generally related to a system for optimizing an eight-dimensional (8D) audio signals in a pair of three-dimensional (3D) spectacles.
BACKGROUND OF INVENTION
[0002] Typically, the spatial sound combines the interactions between the acoustic sound waves, the room or space, the interaction with the user’s head and ears, the reaction of the users middle and inner ear and the audio nerve, and finally the brain’s cognition and interpretation of the acoustic scene.
[0003] Following are the differences described when the user is using stereo headphones and speakers for listening to any audio files.
[0004] When the users listen to a left/right speaker configuration, the signal from the left speaker arrives at both the left and right ears and is summed with the input from the right speaker. When the users listen to the same content on headphones, the left ear receives only the left channel, and the right ear receives on the right channel.
[0005] After propagating through the air and before arriving at the eardrum, the soundwave undergoes filtering and delay effect due to the size and shape of our head and ears. The wavefront arrives at the ears at different times and with different frequency shapes. The delays and filters will depend on the angle from which the sound originates. When listening to headphones, this filtering and delaying effect is essentially bypassed, and the direct signal is inserted almost directly to our eardrums (depending on the headphone type).
[0006] In the real world, and even in the driest studio, the direct sound from the speakers is not the only thing that arrives at the ears. The soundwave interacts with the room by bouncing off the walls and other physical objects creating multiple highly correlated signals coming from numerous directions. These are referred to as early reflections; they also undergo filtering and delaying based on the direction from which they arrived. Our brain uses the gains, times of arrival, and directions of these early reflections relative to the direct source to estimate the distance of the source and the dimensions and acoustic characteristics of the listening space. Again, on headphones, none of this happens; only the dry signal is introduced to the ear, and there is no indication of how it will interact with a physical environment.
[0007] Since all of the above-described phenomena depend on the direction of the sound, even the slightest nudge to the user’s head causes the complete audio scene to shift in the opposite direction because the external world is not moving with the head. Now, this cue is as crucial as any of the others—perhaps even more so. The brain, being highly sensitive to change, remembers where the sound used to be and where it is now, combines this with its knowledge that it (and not the source) has moved, and uses this information to locate the static external source. When the users listen on headphones, the audio scene constantly moves with the head, contradicting any previous supposition the brain has retained regarding the location of sound sources.
[0008] All of the above are imperative cues that the brain uses while continually making decisions about the location of sound sources. Now, the brain is not a rash decision maker, and it is not easy to fool. It has developed the ability to localize sound through millions of years of evolution. To know by listening where a predator might be lurking or where prey can be caught is crucial for survival. When sound cues are missing or contradicting, the brain becomes confused until it ultimately gives up the attempt to locate the sound, and the scene collapses into our head.
[0009] Since the cues that help the users to locate sound sources in space are missing, the users hear the sounds as if they are nested within the head. All the elements we are hearing are crowded along the two-dimensional line stretching through the head from ear to ear instead of the three-dimensional space outside of the users head.
[0010] The flatness of the ordinary headphone experience can have several negative consequences such as 1. Wrong or missing spatial image: when listening on headphones, the user either fails to perceive or misunderstands the spatial intentions of the mix that the producer or recording artist wanted to convey.
[0011] For example, in the Beatles’ song “A Day in the Life,” the vocals start on the right channel and the piano on the left. Then, in the course of the song’s first verse, they gradually move towards each other, until by the second verse they’ve completely traded places. This is an essential part of the listening experience, and we can hear the transition properly occurring in the auditory space when we experience it through speakers. Listening to the song on headphones with flat headphone sound will not reproduce this auditory scene properly, and the experience will be greatly reduced.
[0012] 2. Mixing decisions: When the user mixes audio on headphones, contradicting spatial cues can be perceived as frequency or phase differences. This might cause the sound engineer to make incorrect or exaggerated EQ and mixing decisions that will become apparent only once the track is played on speakers.
[0013] 3. Listening fatigue: The inner-head experience created on headphones can cause listening fatigue since the brain is not used to this type of sensation. The brain is continuously trying to comprehend the spatial audio scene, but the cues are either contradicting or missing, leaving the brain in a constant state of confusion.
[0014] 4. Surround Sound: It is practically impossible to create surround sound on ordinary headphones, primarily because they cannot convey the surround image of sources located behind the listener.
[0015] Therefore there is a need for an effective and efficient system to bridge the gap between listening to sound from external sources and listening to headphones. Further, there is a need for a system for optimizing an eight-dimensional (8D) audio signals in a pair of three-dimensional (3D) spectacles. Furthermore, there is a need for a system to integrate all of the above-described missing cues into a signal to convince the brain that sound is coming from virtual speaker positions in space, with options for both stereo and surround.
[0016] Thus, in view of the above, there is a long-felt need in the industry to address the aforementioned deficiencies and inadequacies.
[0017] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.
