Acoustic enhancement & immersive sound
Which applications? For who?
SIAP is intended for theatres, concert halls, culture houses, music schools, conservatories, auditoria, places of worship (churches, mosques, synagogues etc), arenas, stadiums, restaurants, outdoor venues, sports halls, leisure venues, rehearsal rooms, artist’s (home) studios, conference halls, museums, jazz clubs.
In short, the scope of SIAP is virtually limitless. This way SIAP transforms any single purpose hall into a multifunctional venue or room that becomes optimal for any kind of performance with unamplified as well as amplified sound. Besides variable acoustics (from theatre ambiance to large church acoustics) the SIAP system can also be used to create ambiance and atmospheric enhancement (i.e. immersive sound), or in combination with the reinforcement system for a more comprehensive sound experience, for example in a pop/rock concert a musical or to support a movie with surround effects (5.1 / 7.1 /9.1). And all this in a natural way, without artificial processes.
SIAP welcomes you in the electronic acoustic architectural world of the 21st century!
How does it work?
A small tour
A small number of microphones (usually four) high above the front of the stage capture the sound.
They feed the stage sound of the performers, orchestra, choir etc. with all of its information such as source location(s) and their tonal quality to the SIAP acoustic processor.
We add some ambiance microphones above the audience to have some extra ambiance and interaction between audience and actors.
The SIAP processor is a very powerful sound processing “system”. In this the sound is treated with appropriate time delays, filters and reverberation fine-structure based on the desired acoustic.
For this purpose the processor comprises a large number of independently digital programmable channels.
Because of the large number of channels, it is possible to create more acoustical zones, each with their own envelope and reverberation time.
The SIAP system is very user friendly. No specialist knowledge needs to be at hand to operate the SIAP system. Simply choose between the acoustic presets (optional wireless).
For example: (unamplified) speech as in drama, operetta/light opera, grand opera/classical ballet, chamber music, non-classical unamplified ensemble, chamber orchestra, large orchestra, choir/vocal group, solo piano. Amplified: ambiance, fill-in, surround.
Changing between (movie) surround presets and users presets are just as easily.
The output from the processor generates a “sound blanket” that covers the entire room (and orchestra pit and /or stage). This sound field, that is exactly the same as the reverberation time and corresponding nuances as set in the processor software, forms the optimum acoustic together with the hall itself.
The SIAP system creates this sound field by building up reflections, reverberation etc. in exactly the same way as the natural reflections and reverberation in a hall itself, while keeping the orginal acoustic character “signature” of the room.
This sound is reproduced in the hall through high quality power amplifiers and about 50 to 200 loudspeakers, distributed over the walls and ceiling.
All of these individual loudspeakers contribute for one or two percent of the total contribution which makes each loudspeaker individually unnoticeable to locate.
We like to use high quality loudspeakers with a very wide dispersion and an outstanding polar diagram to create a uniform dense and diffused soundfield.
SIAP’s natural process preserves the natural balance, the correct localization and the timbre of the sound sources on stage (instruments, singers, actors).
With a SIAP system a spectator can close his/her eyes and still localize the source position, which then appears to be exactly correct when the eyes are openend again.
Of course the same correct localization correctness applies to sound sources moving around the stage area (walking singer, actor or musician). At SIAP demonstrations this is always a nice experience.
Suitable For Unamplified Music.
Add the natural early and late reflections to the direct sound to give the audience and the musicians the joyfull experience the way it should.
Suitable For Amplified Music.
Add the proper ambiance to the room to give it a more lively feel, or combine the FoH installation with the SIAP system for optimum results.
Suitable For 3D Surround.
Create a surround matrix with multi in and outputs. Create a configuration for a show or musical and save it. Incorporate SIAP in an existing environment with surround.
