The future of sound is VR

3dsoundThere is one company that is truly making waves when it comes to 3D sound; an unheard of research company in Germany called Fraunhofer IIS. The reason this company is being noticed by Korean giants such as Samsung and LG is because they have successfully created 3D surround sound audio tech and has partnered with them for Samsungs Gear VR and LG’s new smart phone, 360 VR.

Fraunhofer came up with internet audio and 3D sound for VR and they are setting their sights on new frontiers for new innovations in sound in the relatively new field of virtual reality

So why should the world take notice of this new technology?

Fraunhofer IIS has created audio codecs which have been used in over 8 billion devices which have been licensed by over 1000 companies; Spotify and YouTube are just but a few.

Even when it comes to compressed audio, VR completely changed the way the quality of entertainment forever. Fraunhofer changed the way we listened to media though MP3. Without it, gadgets like the iPod would never exist; neither would Netflix, Spotify or YouTube which rely on compressed audio to function.

VR hopes to do the same with mobile file codes HE-AAC and what they company views as the ‘next generation’ codec MPEG-H.

First, let’s see how 3D sound affected our lives.

When it comes to surround sound Dolby Atmos is a well known term. Dolby and DTS were pioneers in creating mix and master audio tracks based on sound objects. Traditionally, sound mixing was limited to recording and mixing audios into precise channels. But with the ability to move individual objects, like a helicopter allowed to move freely through sonic space, this effect proved to radically change the way we hear objects, sounds and musical beats.

In a Dolby Atmos movie theatre, you can experience this feature fully. Lasers and rockets fly from front to back of the theatre and rain drops seem to come from above with speakers mounted on the ceiling and so much more. This created more realistic theatre experience making the experience more powerful and memorable.

Use of VR in cinema

vr-soundVR however might prove to be an even better medium for sound objects to roam. Realistic sound plays an even more important role in the cinema because sound impacts the way we process information. For example, sound reflections can tell us whether we are in a small room or whether we are in a huge open space. So in movies, when a car is driving down a road or when a character is running in a hallway, the sound needs to be realistic in space.

Sound also helps guide the plot and in a scene, a sound on the left directs the viewers eyes to turn in that direction and holds the users attention and creates suspense. If you hear a crashing sound behind you, chances are you will naturally turn to see what happening and the directors can use these cues to steer the movie along.

In addition to this, Fraunhofer’s audio tech incorporates head tracking cues which means even if you turn your head, the sound stays put.

The research lab

Fraunhofer has an advanced audio lab which they claim is one of the top most sophisticated labs in the world. They have developed 3D microphones to be able to capture 3D sound in a better way in a live environment. This enhances the 3D sound recording process from start to end.

Fraunhofer’s system starts with its 3D surround plug in which can work with literally any digital audio recording software. This makes it easy to move sound objects in a virtual 3D environment and uses minimal processing power.

VR in mobile devices

When it comes to mobile devices, a high number of smart phone users’ stream music and movies through their devices and they also want a good surround sound experience. Speakers on mobile speakers are too small so Fraunhofer came up with its own hardwa re for virtual surround over headphones with the creation of Fraunhofer Cingo; a library which allows you to have virtual surround using regular head phones.

This is also what Google incorporated the HE-AAC codec into Google Nexus devices, so did Samsung for Gear VR and LG’s 360 VR.

The goal for Fraunhofer is to allow audio professionals to easily render high quality 3D surround sound files in an open source environment which may allow for the most brilliant and best innovators in VR to create ingenious work, making the future of audio very promising.

Invention and History of the Telephone

Graham-BellThere aren’t many of us who don’t take the telephone for granted in today’s era, but in the grand scheme of things it really wasn’t that long ago when they didn’t exist. Although a ‘tin can’ variety of magnetic, acoustic voice broadcasting device had been around for a few centuries beforehand, Alexander Graham Bell’s first telephone prototype, featuring electronic, micro-phonic implementation didn’t come along until 1876.

Earliest Telephone Experiments

Historians tell us the earliest telephone experiments took place between 1664 and 1685 by British physicist Robert Hooke. By 1667, he had invented a crude, but effective string phone. It was Hooke’s idea which helped bring about the progression of magnetically powered telephones. While these certainly didn’t produce as strong a signal as electronic phones, they were used quite predominantly among those who could afford them.

Acoustic Phones Competed With Electronic Phones

Believe it or not, there was a time when the older, cruder magnetic versions of the telephone competed with the earliest versions of electronic phones. Vying for control of the telephone market, manufacturers took full advantage of Bell’s expiring patent. 300 or so patents later a magnetic phone which could reach as far as a half mile had been manufactured. Many of these phones were used at railroad right-of-ways.

Needless to say, the magnetic telephone soon faded out of existence as electricity became more easy to harness and could be applied to the telephone. While Alexander Graham Bell is credited with the first US telephone patent, there were several inventors in the 19th century who contributed to its quick progression.

Antonio Meucci, – In 1854 the Italian inventor constructed telephone-like devices which were used by many for communication.

Johann Philipp Reis – 1860 – Reis constructed the earliest versions of ‘make-and-break’ telephones, which today are referred to as Reis’ telephones.

Alexander Graham Bell – Was awarded the first US patent for inventing the telephone in 1876.
Elisha Gray – 1876 – Using a water microphone invented a telephone which was rather popular for a time.

In 1876, Tivadar Puskas was credited with creating the first switchboard exchange.

Thomas Edison is famous for inventing the first carbon microphone, which provided the telephone with the strongest signal yet known at that time.

First Commercial Telephone Exchange Board

telephone exchange boardIn 1876, while working with Thomas Edison, Hungarian engineer Tivadar Puskas began work on the first telephone exchange board. Up until this time, telephones could only work through one direct line connected from one home or business to another.

Following many trial and errors, Puskas and his investors opened the first commercial telephone exchange center in New Haven, Connecticut on January 28, 1878. Less than two years from the day, Puskas and Edison had first started on the endeavor.

20th Century Growth of the Telephone

More than 3 million telephones were being used throughout the United States by 1904 and by 1914 they were leading the world in telephone density. Telephone installation and usage in the US continued to grow and lead the rest of the world in the 1900’s, with several residents of England still not using a phone up until the late 1960’s.
history-of-telephoneUntil the 1930’s a separate ringer box had to be used for telephones, but soon the bell and induction coil were being constructed within the phone unit. Batteries had been used up until the 1930’s as well. It was at this time where power could now be provided to the phone subscriber via central office batteries.
The following 30 years saw the telephone progress in size and efficiency, whereby the late 60’s the rotary dial was replaced with touch-tone technology.

Early History of Mobile Telephones

Two-way radios installed in taxicabs, police cruisers, railroad trains and other civil vehicles set the stage for the eventual fruition of mobile telephone capability. As early as 1947 Bell Labs engineers Douglas H. Ring and W. Rae Young entertained the idea of directional antennas which could pick up 3 signals at a time, instead of just one using hexagonal cells. The full technology wasn’t realized until the 1960’s, however.

cell-phoneThe first cellular phone call took place on April 3, 1973, by Martin Cooper, the manager of Motorola at the time. Dr. Joel S. Engel, head researcher at AT&T’s Bell Labs was the receiver of the call.

Through the invention of cable, fiber optics, and WIFI we get the telephone technology we have today. While the gist of the electronics of the modern telephone didn’t change very much for several decades recent technological advances have been taking place at light speed rates. The telephone has come a long way in a relatively short period of time.

Communication usage in sites – Rise of WebRTC

phone-technologyInternet communications have come a long way in the past decade. With the invention of Voice-over Internet Protocol (VoIP), this technology is now much more available to the general public and allows certain chat services to be much more accessible.
Certain technologies like Web Real Time Communication (WebRTC) are highly efficient, which allow for audio and video chat platforms to be utilized without the need to employ plugins, downloads or installations. Although, very hard to utilize and incorporate into a business and use properly. I came across a website that uses this software highly efficiently and allows users to benefit without all the technical “know how”. The site utilizes this phone technology [NSFW] and it’s very advantageous to the consumer, who may not understand the technicalities of specific software.
Both phone and internet related – are among some of the fastest used for video and audio chat in the industry. They pride themselves in bringing their customers the most comfortable, dependable and convenient call experience possible and we definitely agree with them.
Phone lines still work well when it comes to chat communications, however, it is more expensive and they can only handle so many people at one time. While the above site employs many call takers, this technology has become less common with the new advent of software’s such as WebRTC. Users can now connect with their favorite sex talk models via the most modern and reliable audio / webcam instant messengers available today.
webrtcWebRTC works by passing data between browsers for communication, gaming and file transfers. In this case, communication is the data that needs to be addressed. It can be a rather involved and complicated process, sometimes causing a delay between the two or more parties communicating. If you have ever engaged in a video chat with someone on the other side of the planet, you can relate to this result. Due to the massive amount of data that must be transferred from one party to another over a VoIP line, at this stage in modern technology it is an unavoidable side effect.

Today, we have a potpourri of items to cover:

So, here it is in a nutshell.

The whole idea of WebRTC is to allow you to see and talk to someone via your browser in a live environment.

Captain_Kirk_plzSo, think of it in terms of Star Trek. Captain Kirk whips out his communicator and talks to Mr. Spock and everything is taken care of, he gets the girl and everything is right with the universe. But the catch is that it’s all voice and we know body language is 50% or better of the content of any message.

With WebRTC, Kirk can hold a conference with realtime video, sound, and with all the ship’s department heads, and get their take on a situation to make the best decision possible. He sees their body language and taps into the nonverbal channels that are part of our everyday communications.

Not as exciting from an action adventure TV series standpoint, I admit but much more cost effective and everyone is on the same page at the same time at the end of the day.

Cost Savings and Benefits

The primary benefit is that you can use P2P platforms. This means off the shelf webcams and microphones can be used. This also means no more having set aside special conference rooms with expensive hardware, hard or satellite links to get everyone online.

At Places like Chase Manhattan on Dearborn street in Chicago with their state of the art video conferencing room on the 33rd floor, it all becomes moot and you free up a floor and have an extra million dollars to put back on the bottom line.

Everyone’s PC now can act as a two-way link, which later will include iPhones as well as other handheld devices.

Now every employee of you company can participate in group discussions and meetings. This changes your company from a lumbering behemoth to an agile lean predator gliding through the jungle of business markets today.

This is the simplified explanation of course.

Tune in next time when I will show you how the Apps actually accomplish this miracle for you. Until then this Juli signing off.
