Gone are the days where brides are only focused in just one color, white. White is a symbol of purity, which therefore means that it is perfect for weddings. But as the fashion industry evolves, brides are getting more and more liberated when it comes to their ideas. These ideas may raise eyebrows, especially with the older crowd, but if it’s not their wedding, then there’s nothing to worry about. Your wedding, your rules!
In this article by Scott Taylor, he talks about the different wedding ideas for a quirky bride:
Has the normal, white on white (maybe a purple twist?) wedding just become a little… dull for you? Are you bored of hearing the same old songs? Lauding over the same old floral centre pieces? Or, are you simply not a fan of cake? Well, if you’re a Bride who dreams of hosting something a little different; a wedding which has a multitude of quaint moments that make your guests go ‘woah’ or ‘aww’, then you’re in for a treat! Take a look at these 10 alternative wedding ideas below and note down any of your own ideas in the comments section. See full post here…
With these wedding ideas, your wedding will surely get to standout!…
The visual and sound sensations that they create in the audience must be approached with a high degree of similarity to what is perceived in the real context they intend to recreate.
High realism audiovisual environments
To achieve total immersion, the audiovisual interface must include both image and sound in the same way that the user would perceive in a real situation. For both stimuli, the human perception system can obtain a three-dimensional sensation of space using two sensors, that is, two eyes and two ears. It would, therefore, be possible to recreate the relevant feelings if a realistic perception of the image in space is provided in conjunction with a sensation of spatial sound.
Regarding the image, two technologies are usually used to produce stereoscopic images: those systems in which the user uses special glasses (polarized, sealed or anaglyphics), and on the other hand, auto stereoscopic viewers that provide three-dimensional perception without glasses specials or alternative device.
Regarding sound, the
simplest and most widespread method for providing spatial audio is stereo,
which has been used for the last 50 years as an added value of sound
recordings, especially in music.
Since the mid-70s have
been used in cinemas initially and at home in recent years, the surround sound
systems ( surround ) that try to provide a better feeling than the stereo using
more channels of reproduction
However, these systems
are only intended to increase the sense of spectacle in film projections by
artificially adding in the production processes, special effects, explosions,
reverberation in rear speakers, ambiance, etc.
But they do not provide a real sense of 3D sound. Also, the useful listening area ( sweet spot ) is practically restricted to the center point of the speaker circle, degrading the perception outside the center. When it comes to realistic multimedia immersion in video conferencing, these systems are not suitable since their purpose is to reproduce effects in movies and subsequent speakers do not add any significant contribution to the meeting.
Another much more realistic strategy is to reproduce directly in the listener’s ears the signal that the listener would hear if it were in the acoustic space to be simulated. The sensation obtained by the listener depends on the fidelity of this reproduction. This strategy is commonly called binaural signal reproduction and can be done with both headphones and speakers. Also, the 3D sound signal can be synthesized if the listener’s HRTF ( Head Related Transfer Function) function is known.
As this system is susceptible to variations in the position of the listener concerning the optimal reproduction position, in practice, they are only valid for a single listener and in highly controlled listening environments, e.g., a user in front of the screen of a computer.As an alternative to surround sound systems, there are more advanced systems such as Ambisonics or Virtual Surround Panning that are suitable for more or less restricted listening areas, although always somewhat more significant than binaural systems with cross-talk canceler.
. The solution to extending the listening area in these systems involves increasing the number of speakers used, with the complexity and difficulty included, as well as making the transmission formats more flexible.…
Professionals visiting the Hall will be able to see first-hand the latest solutions from manufacturers, distributors, integrators and service companies with proposals for both traditional broadcasting and new audiovisual environments.
Throughout a large exhibition area, professionals visiting the Hall will be able to see first-hand the latest solutions from leading international manufacturers such as Canon, and its wide variety of cameras and lenses, or Riedel Communications with an extensive portfolio of solutions for intercom and audio, video and communications networks.
It should also be noted that another year of AEQ, a manufacturer based in the Technological Park of Leganes (Madrid) and that exports its automation and production systems worldwide (broadcast monitors, intercom, Audio Codes, consoles, commentator systems, reporter units …)
On the other hand, in the radio area, it is worth highlighting the participation of World Cast Systems that will exhibit its latest proposals in coding and audio processing, transmission, signal monitoring.
In BIT Audiovisual 2018 you can also learn about the solutions that for virtual studies, augmented reality and integration of social networks in graphics is developing Brainstorm, a company that under the seal “made in Spain” is breaking barriers in five continents.
No less critical and essential are the companies dedicated to the manufacture of wiring and connection solutions such as Lemo or Person whose developments are allowing to transport and manage signals with 4K and higher resolutions.…
However, the most promising system nowadays to provide a sensation of sound immersion in a vast area is the so-called Wave Field Synthesis ( WFS ), whose fundamental difference is that the sound field is synthesized using a system of loudspeaker arrays for the entire audience area, eliminating the preferred listening area. In this way, a listener can perceive the same sound sensation anywhere in the listening area. Also, WFS synthesizes the acoustic field that a listener would see in the actual listening area, including naturally all the localization tails and effects that the wave would cause in the listener.
This technique of sound reproduction, which is based on the propagation of waves, consists of recreating an acoustic field within a volume from the signals recorded on a surface, by analogy to holography and according to the Huygens principle. According to this, a wavefront of a point source behaves as a set of several secondary sources, which in practice are replaced by loudspeakers. Thus, the algorithm for calculating the signals with which each of the speakers is fed takes the audio signal that would arrive from the virtual source to each secondary source as the data source. Therefore, the WFS system must consider numerous data such as source coordinates, number of fronts and side speakers, speaker spacing, etc.
One of the distinctive characteristics of the surround above audio systems is the suppression of the preferred listening point. This feature is very desirable for various multimedia applications, such as real-time video conferencing, in which multiple participants located at different locations in a room interacting with other remote participants, also spatially distributed in a place. The sense of realism is assured by providing listeners with the amplitude and direction of arrival of any sound message that comes to them, both from the speakers in the same room, as well as from the remote office.
However, there are still open problems to solve, which are currently being studied by researchers, and are based on the practical simplification of the technique. The distribution of secondary sources is not infinitely dense and continuous, but a finite set of individual loudspeakers that receive limited band signals and which, in turn, form a limited reproduction area in space. These two effects compromise the performance of real systems, creating imperfections in the generated wave above a limiting frequency, called spatial aliasing frequency.…
