Last updated: February 25, S ound is wonderful—think of Beethoven or birdsong. But sound we don't want to hear, in the wrong place, at the wrong time, is simply noise: a nuisance that can make life stressful and work, study, or sleep impossible. If you're plagued by a noise problem, the simplest approach is to kill the sound at its source, but sometimes that's just not an option. If you live near a construction site, a noisy bar or nightclub, or you have an elderly, forgetful neighbor who plays the TV through your wall at full blast, getting the volume turned down may be very hard work. Maybe you have the reverse problem: perhaps you have a noisy occupation or hobby—you might be a practicing musician or a DJ—and you want to spare the people around you from suffering the sounds you make.
My name is Dale Newton. I am a professional Cellist and Composer and live in St. Paul, Minnesota. The first issue is carefully choose a recording environment where extraneous noises are minimal or can be reduced or eliminated. If you are not in an ideal sound recording studio, look around the space and listen quietly and carefully for room noise and where it comes from.
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation. The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone , phonograph , and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting , as there were many problems with studio-to-transmitter links.
