When considering about audio, patents may possibly not be the initially variety of IP appropriate that springs to mind. We are all common with artists staying sued for copyright infringement or even how some popstars have registered logos for the lyrics of their tunes. Even so, the globe of tunes is prosperous with novel and creative technological progress. So, let us choose a glimpse at 3 innovations connected to the planet of songs and concerts.
And it was all yellow
Considering that 2012, Coldplay have been regarded for, amongst other issues, Xylobands – the light-up wristbands they give to supporters at their demonstrates. These wristbands are designed to synchronously illuminate with various colours in time to new music. But how do they function? Patent software WO2023/021209 has the facts.
Each wristband contains an RF receiver which detects “data bursts” emitted by a transmitter. The information bursts include guidelines which inform the wristbands when to light up and with what colour. When concertgoers arrive at a location, they are supplied a wristband assigned to the zone of the location they are positioned in. For occasion, if an attendee’s ticket is for the north-west aspect of the venue, then they will be offered a wristband that has been pre-assigned to this zone. Then, once the live performance starts, the transmitter sends out info bursts that contains data for all the distinct zones. All the wristbands get all of the transmitted knowledge bursts. Then, each wristband filters as a result of the data been given for the guidelines relating to the zone it has been assigned to. The wristbands then gentle up according to the instructions they obtain. This allows organisers of functions to coordinate intricate lighting displays which can even be synchronised to tunes and other exclusive results.
It is a type of magic
We have all been there – you are out and about and you hear a tune enjoying. It seems familiar, but you aren’t rather guaranteed what it is named. In the previous, the track would have been caught in your head for the relaxation of the day and you may possibly never ever have learnt its title. The good thing is, we now have Shazam or, instead, luckily for us we now have US patent 6990453 B2 – “system and technique for recognizing sound and audio signals in higher noise and distortion”.
As the patent points out, this new music recognition operates by indexing tens of millions of identified tracks in a database and assigning every single a assortment of “fingerprints”. The fingerprints are identified by analysing quite a few smaller “chunks” of a music at diverse points in time. For every chunk, a frequency spectrum is established based on the a lot of unique frequencies in the audio at the offered position in time. The frequency spectrum is made up of facts on which frequencies are present and how loud each individual frequency is – known as a Fourier change.
When the procedure starts off to detect a track being played, it carries out the exact fingerprinting approach on the sample recorded, identifying the loudest frequencies for every of many little chunks. When the fingerprints are collected, they are in contrast to the fingerprints in the databases of music and the tune with the highest quantity of matching fingerprints is chosen as the right match. The duration of and time concerning each individual chunk is carefully picked to make certain adequate detail is captured without having having as well lengthy to process. Employing this method, an almost real-time assessment of a track can be realized. Uncomplicated! Or possibly not basic, but at minimum you are going to ultimately know the title of that track.
I really feel it in my bones
You know the emotion when the tunes is so loud that you can really feel it in your bones? Effectively US Patent 10,765,959 normally takes that a single action further more by earning the ground shake beneath your toes! Making use of a person or a lot more vibration actuators, this “sensory floor” promises to “stimulate a person’s non-auditory senses to perceive a musical general performance extra immersively”.
The sensory floor is produced up of various surface tiles which can be arranged at a venue to protect the sought after ground area. The tiles are linked to a mixer board which functions as an interface amongst a performer’s musical products and the vibration actuators.
A performer is then in a position to possibly feed their are living tunes straight into the method to have the sensory flooring answer in real time or alternatively they can play again a pre-recorded established of vibrations. The flooring can be established to vibrate in time to new music to “enhance satisfaction of a musical performance” and at selected frequencies the actuators in the system can even bring about a resonance in the lungs of all those standing on it to heighten the feeling of getting immersed in the new music.
So there we have it, three tunes-relevant innovations which you may possibly not have recognised about. There’s a ton far more to intellectual property in songs than just copyrights and trademarks.
