Out of demand, DSPPA conference system supplier has developed an Immersive Sound System to provide a new sound experience of "consistency between the perceived voice and source orientation". We use patented algorithms to achieve high-precision sound source positioning and provide wider acoustic space to give the audience a sense of immersive acoustic encirclement. By doing so, precise positioning of sound can be achieved, immersive, dynamic sense can be made, and consistency between the sound and sound source can be realized.
A high-performance pour input and eight-output immersive sound processor equipped with network ports RS-232, RS-485, and GPIO interface to achieve rapid configuration and remote debugging and monitoring, can be controlled by the centre control.
Web Page Control
Adopt a special web page adjustment controller, the web operations page is flexible and convenient.
Converted to digital applications through proprietary algorithms, highly accurate sound source localization is achieved through complex and efficient processing by DSP.
16 Positioning Points
After calculating multi-channel and multilocation data through high-performance DSP, it provides 16 localization points, which can realize the function of sound source localization in 16 locations in a conference venue.
The tuner can achieve positioning, extension, movement and adjustment of the distance of sound objects
Sound is where it goes
Let the audience feel the delicacy of the sound restore the real sound achieve the effect of "what you hear is what you see" and shorten the distance between the performers and the audience.
In traditional lecture hall pa system, to ensure the rear audience enjoys a sufficient sound pressure level and more even sound field, speakers are usually placed on either side or above the podium (stage, podium), or positioned at the back of the hall, even in the ceiling. Hence, there is a long-standing inconsistency between the sound perceived by the audience and the orientation of the sound source (speech, presentation, singing, instrument playing, etc.). There are two problems to be specific:
1)For stationary sources, panning varies from audience to audience;
2)For motion sources, panning remains the same for the audience.
Out of demand, DSPPA has developed an Immersive Sound System to provide a new sound experience of "consistency between the perceived voice and source orientation". We use patented algorithms to achieve high-precision sound source positioning and provide wider acoustic space to give the audience a sense of immersive acoustic encirclement. By doing so, precise positioning of sound can be achieved, immersive, dynamic sense can be made, and consistency between the sound and sound source can be realized.
DSPPA Immersive Audio System adopts the new sound reinforcement concept of "spatialization of sound" to create a virtual reality sound experience of "consistency between the perceived voice and source direction". With an immersive sound processor (D6686), using innovative placement and sound processing algorithms, participants and speakers can stay highly aligned with panning rooted in complex and efficient DSP data processing and high-precision acoustic source positioning analysis, acquiring a sense of immersion. The system has resolved the above-mentioned inconsistency, realizing that the audience in different corners perceives the sound of the same volume from the actual source. The audience's perception of panning varies from moving sound sources.
● Traditional Digital Conference VS Immersive Sound Conference:
Traditional Digital Conference System: The sound to each seat comes from the closest speaker (e.g. If the spokesperson stands in front of the speaker, he/she feels bad as sound comes from behind).
Immersive Sound Conference System: In this system, highly realistic sound can be provided and precise positioning can be realized. Regardless of the speaker's orientation, and wherever the audience is, the sound perceived by each seat is heard from the speaker's direction, ensuring the consistency of sound and source, as well as the powerful sound effect and giving participants a better sense of immersion.
● Steps of System Architecture are as follows:
Immersive Sound System is designed for live sound spatialization and immersive experiences, enabling listeners to perceive the location and movement of sound sources in two- or three-dimensional space. The system has two algorithms that determine the placement of the speakers and the processing of the sound signal. Establish a three-dimensional model based on measurement information of the targeted space. The system uses the core algorithm to determine the placement of the surrounding boundary speakers, top speakers, and bottom speakers within the three-dimensional model, and adjust and output the speaker parameters.
1)Establishing a three-dimensional model based on the measurement information from the targeted space, including the spatial stereoscopic shape, the position of the speaker and audience, and the effective area;
2)Determine the placement of the top speaker and the projection area of the effective area at the top of the space;
3)Determine the placement of the bottom-middle speakers and set the centre area that the spokesperson faces within the effective area as the primary speaker point;
● System Connection Diagram
An immersive audio video system for auditorium can be built by the combination of an Immersive Audio Processor D6686, a central control host D6401, multiple multichannel amplifiers, 4 serial array speakers and 12 professional wall-mounted speakers, as well as multiple Dante or digital hand-in-hand microphones.
The 4-channel audio signal input processor is vital to achieving sound spatialization, which conducts DSP multi-channel sound data processing in a high-speed and efficient manner. Each channel provides up to 16 preset positioning points, enabling source positioning up to 16 positions within a conference.
Four-in, eight-out immersive sound processors, in combination with multiple amplifiers and speakers, form an immersive sound system.
● Unparalleled Benefits of the System:
(1)As the sound source expands, Immersive Sound System ensures an even sound field, allowing the audience to distinguish the specific orientation of the sound source, thus guaranteeing the consistency between the audience's perceived sound and the sound source, enhancing the audience's sense of nature, intimacy and involvement. The system fosters a good sound scene.
(2)The Immersive Sound System is easy to set up, and requires no post-production, complex analysis of the construction environment. With simple system commissioning, the system setup time is greatly reduced. With the help of a user manual, relevant field technicians can quickly set up the system and can fine-tune the scenarios to suit the desired scene, making it simple to operate.
(3)The Immersive Sound System uses different delays, which greatly reduces the amount of feedback the speaker can give to the microphone during acoustic signal processing, reduces whistling, and makes the PA system more stable.
(4)The Immersive Sound System can be used in combination with face recognition (check-in, behaviour analysis, etc.), paperless, and other solutions to create a smart, convenient, and user-friendly conference system.
