Sound Engineering, which is also often referred as Audio Engineering, is a branch of audio science. Characteristically, sound engineering refers to the recording, copying, editing, mixing, and reproduction of sound by means of electronic and mechanical devices. Sound engineers employ a variety of recording devices such as high-tech microphones that are required to record even the slightest sound variations. Electronic mixing boards or console boards are an essential element of sound engineering that are used to control sound input while recording or editing music. They include a variety of switches, dials, lights, and meters. Lights and meters facilitate the engineers to understand exactly the sounds that are recorded and their intensity.

By means of switches and dials on the mixing boards, sound engineers monitor the sound input in terms of the volume, and sound quality. Other integral components of sound engineering include digital audio workstations, signal processors, and sequencing software. In movies, sound engineers and technicians incorporate the voices of actors in the movie sound tracks along with special sound effects. The movie ‘Apocalypse Now’ produced in the year 1979 is considered as a classic example of ’sound’ films till date.

Sound mixers, also known as sound boards or sound consoles are the most general type of audio equipment in the audio production world. Each sound operator should know about the different sound mixers available and the correct way to use them. A sound mixer take two and even more signals, merges them together and offers more than one output signal. In addition to mixing signals, sound mixers enable to adjust levels, improve sound with effects and equalization, make monitor feeds as well as record various mixes.

Mixers are available in wide variety of designs and sizes from massive studio consoles to little portable units. Mixers are generally described through the total number of channels they sport. For instance, a 12-channel mixer includes 12 input channels. That is you can put in 12 individual input sources. You may also notice a specification like “24×4x2” that signifies 24 input channels, four subgroups and 2 output channels.

A music studio contains more equipment than just microphones and a keyboard. To produce a world class album, you need to get the best sound out of the artist and the music. One person whose job it is to do this is the music recording engineer.

When I think of an engineer, I think of an architect or someone who tinkers with wires and circuits all day. In the music business, they use a different type of engineer. He is called a recording engineer and his job begins as soon as the artist starts to sing.

The area that the recording engineer occupies is called the digital audio workstation, or DAW. This workstation contains all of the technical gadgets an engineer needs to fine tune the sounds he hears. The engineer works with the artist to lay down the best sound they can get. This may involve the artist recording certain parts of the song several times until just the right sound is achieved.

Helo and welcome!

For this tutorial i am using a sound file of a vocal recording. I will be using ‘adobe audition’ to edit this sound file. ‘Adobe audition’ is a popular brand of multi track recording software. This software allows you to record, edit and mix sound files/recordings. It has loads of tools to edit/engineer your sound files exactly as you would like them to be.

This tutorial will show you how to use the noise reduction tool to remove unwanted sounds/background noise from a recording or any sound file. I am using adobe audition for this example but any decent sound editor will have this tool.

The first step is to identify an appropriate section of the sound file that contains the noise. A good area to find is that which represents a pause between the speech/vocal. Just like when you take a pause between your sentences or words when you are speaking normally. It is useful to zoom in using the software to get a nice clear view of the part u would like to work with. This is the section that will be used to clean up the entire sound file. Once you have zoomed in on your chosen section it will be apparent that where it should be a silent pause there is actually a quiet noise. This is the section that we will sample and then remove from the entire sound file.
