He runs from pillar to post for recognition of his invention, which he says can operate a sound system in a theatre without electricity.
Terming it a ‘path-breaking finding,’ S.V.S.S. Pavan Kumar, 43, a diploma holder in radio and TV engineering and a resident of Visalakshinagar where he has a make-shift workshop, says the device – a dynamic narrow surround processor -- provides a centre surround sound audio from any type of stereo signal.
“It requires stereo signal voltage and no power source to perform the signal conversion,” he told The Hindu . He applied for Indian patent two years ago. If everything goes well, he might get the patent in another three years. Five-year duration is required after notification by the government on the claim for patent.
The audio processor provides very effective centre surround audio (backward and top-ward surround sound) in cinema, home theatre or any musical environment.
According to Mr. Kumar, with conventional two-channel surround technology, the sound field in the back of the theatre can be blurred and is often perceived as coming generally from the left or right. The centre surround speakers at the rear of the theatre reproduce back surround information, when left and right surround information is reproduced by speakers on the sides.
This allows the sound designer to create flyover or fly-around special effects that are smoother and much more accurately placed directly behind or beside the audience as required.
Mr. Kumar says the new surround technology provides filmmakers with a powerful new creative tool for producing realistic soundtracks. On the cost of the equipment, he says it would be around Rs.1 lakh for use in a theatre. He says the trial test made by him at a couple theatres at Kothavalasa near Pendurthy evoked a successful response.
After working in Philips for 10 years, he has been into his research world.
To eke out a living, he undertakes TV and repair of electronic devices.
“The sound processor developed by him needs recognition by the government agencies and he needs a pat on his back for his creativity and innovation,” said Govindrao Adapa, advisor, Vizag Information Technology Association.
