What Is The Difference Between Digital Recording And Digital Recording

Powerful Essays

Digital recording/ reproduction converts an analog sound signal picked up by a microphone to a digital form. The process that allows this is called digitization. This allows the recording to be stored and transmitted by a wider variety of media. Digital recording stores audio as a series of binary numbers. These represent samples of the amplitude of the audio signal at equal time intervals. The sample rate is high enough to convey all sounds that can be heard. Digital recordings are of better quality than analog recordings because the digital format prevents much loss of quality found in analog recording which is due to noise and electromagnetic interference in playback. Mechanical deterioration and damage to the storage medium is also prevented. A digital audio signal has to be reconverted to an analog form during playback before it is applied to a speaker or earphones. Analog recordings rely on making an exact copy of the sound-wave pattern. Making more copies of the original recording can distort the pattern and add extra noises. Because a digital recording is just numbers, it can be copied as well as corrected if necessary. This can be done many times, without any damage to the recording.


A brief introduction to, and the history behind the science of Sound Recording

Sound recording and reproduction is defined as an electrical or mechanical inscription. This is a re-creation of sound waves, irrespective of the source. The two main classes of sound recording technology are analog recording and digital recording. Since 1934, sound recordings (or phonograms) have been treated differently from musical works under copyright law. Copyright, Designs...

... notes of bass musical instruments are around 100 vibrations per second while high notes from flutes and tin whistles are about 1,000 vibrations per second. Bats use sound waves (echolocation) as high as 50,000 vibrations per second but these are outside of our human range (ultrasonic). The ability to quantify physical behaviours is central to building a structured understanding of the system we use to record sounds, and mathematics allows this. The science of measurement of air pressure and velocity of our recorded sound, and the physical and mechanical systems that use gases to transmit sound waves into electrical signals. Is involved. The science behind the actual recording requires mathematics, physics, acoustics, electronics, and more recently psychoacoustics, to explain how we translate physical air vibrations into musical sound that excites our emotions.
