GR je dobar bio, dok nije krenuo bakaluk da ga forsira. I svakoj istini mora da doda trgovački korisnu poluistinu ili neistinu.

Naravno, hiljadu puta je rečeno, da od low level(da izbacimo cenu iz referenci kriterijuma) izrađenih komponenti nema selameta, komponenta mora da je korektno urađena, pa makar bila jeftina kao ruski kond.

Ono što se krije je ded lajn, ne postoji nenormalno skupa komponenta koja će doneti makar i minimalan napredak. Jednostavno je svaka komponenta realna, neidealna, kondovi imaju recimo šest karakteristika, ili koliko god se rascepka, jedno četiri do pet tehnoloških zahvata pri izradi i kraj. Pride, daleko pre tog savršenstva je uvce ostalo ispod senzibiliteta promena.

Ali nema prosperieta bez golicanja mašte.

New technology beams music directly into your head without headphones

DJMAG.COM

---

A new speaker reportedly beams music directly into your head without headphones. In a report last week, The Associated Press revealed that Israeli tech company, Noveto Systems, has developed a "futuristic audio technology" to enable listeners to enjoy solo wireless music - without headphones.

Citat

The new technology, dubbed sound beaming, uses a 3-D sensing module from the speaker, locating and tracking the ear's position to send audio via ultrasonic waves. The waves create sound pockets by the user’s ears, and can be heard in stereo or a spatial 360 degree sound around the listener.

Scientific Reports - Laser-sound: optoacoustic transduction from digital audio streams

Citat

This work presents a novel laser-based optoacoustic transducer capable of reproducing controlled and continuous sound of arbitrary complexity in the air or on solid targets. Light-to-sound transduction is achieved via laser-induced breakdown, leading to the formation of plasma acoustic sources in any desired spatial location. The acoustic signal is encoded into pulse streams via a discrete-time audio modulation and is reproduced by fast consecutive excitation of the target medium with appropriately modulated laser pulses. This results in the signal being directly reconstructed at the desired location of the target medium without the need for a receiver or demodulation device.

 

Citat

Laser-generated sound waves can be very rapid and strong, while they enable the rendering of moving virtual sound sources in space by real-time shifting of the laser focal spot within the possible beam-focusing area. The generated acoustic pulse trains enable the direct reproduction of digital sound streams without the need for digital-to-analog conversion, allowing for all-digital audio reproduction chains.Laser-generated acoustic pulses have been studied experimentally and analytically in numerous works. Ιt is well known that they exhibit an N-wave signature in the time domain, while their frequency spectra extend from the low “subwoofer” audible frequencies up to the ultrasounds
