Sudeep Audio: Sound recording studio, audio cassette and CD duplication, music, book store. Promoting talent in the music industry. Retailing music creating softwares. Database on the music industry in India. Audio consultants.
Sudeep Electronics, the parent firm, was set up as a sound recording studio at Andheri West, Mumbai, by Nikhil Mehta, one of Mumbai's experienced sound engineers, in 1977.
SudeepAudio.com, an audio portal, was set up in the year 2001 with an initiative to promote Indian music and audio products on the Internet, plus, to create a platform of information exchange and add transparency to pricing, new product availability, etc., over the Internet.
The dynamic content of the portal is handled by a dedicated team of talented youngsters.
Needless to say, these comprise sound professionals, musicians, college students, professional writers, and even housewives.
There are several features on the SudeepAudio.com site, like interactive user forums to exchange notes, including the facility of sale and purchase of albums of talented artistes, private albums, books on Indian classical music, music software, studio hardware, P2P selling of used equipment, etc., for the "connected" world.
Today, the website has become a comprehensive mine of musical information.
And on the commercial angle, it has now risen to become one of India's largest e-tail store for pro / home audio software and hardware.

Sennheiser Glossary: an alphabetical list of terms and definitions used in studio recording from the field of acoustics.
AB powering:
Low DC voltage with a high internal resistance for powering condenser microphones connected to pocket transmitters.
AB stereo:
Also known as time delay stereo, time difference stereo. 2-channel stereo recording technique which benefits mainly from the differences in time delay between the microphones (channels). Omni-directional microphones are used in most cases.
Absolute voltage level:
Used in sound studio technology to describe the ratio of a certain voltage Vx to a reference voltage of 0.775V. The absolute level is given in dBu and is calculated as follows: dBu = 20 x log (Vx/0.775). Thus, 0 dBu is equivalent to 0.775V, 6 dBu is equivalent to 1.55V and 15 dBu is equivalent to 4.4V. The current use of dBu relates to a voltage adaptation, while the former use of dBm relates to a power adaptation. The reference voltage of 0.775V is the same for both systems, and is derived from a power of 1mW in a resistance of 600 ohms.
Absorption:
Sound is taken in and converted into heat. Opposite: reflection.
Acoustic amplification:
A weak acoustic signal (e.g. the human voice) may be amplified by using mechanical means. A simple example would be the horn of a gramophone, or horn loudspeakers which are able to produce loud volume levels with little electric power. Further examples would be the bell of a trumpet, the case of a piano or the body of a violin.
Acoustics:
The science of sound.
Active antenna splitter
RF device for connecting several receivers to a single pair of antennas. Includes an antenna booster.
Active antenna:
Antenna with an integrated or attached RF booster which is powered via the antenna cable.
Acute hearing loss:
Suddenly occurring hearing loss or hearing impairment – usually in one ear – caused by interference in the blood supply. It is accompanied by noise in the ear (tinnitus). The condition should be treated quickly in order to prevent the risk of long-term damage.
