Hard Disk / Computer-Based Recording
One of the biggest trends in recent audio production has been to merge digital audio with computer technology to create a sample based approach to sound recording. The encoding of audio data into digital memory or onto a storage medium provides us with a means for storing or manipulating defined blocks of digital data. This data can be stored as a sound file such as .wav, .aiff or SDII.

Perhaps the most important difference that can be distinguished between a tape-based system (digital or analogue) and samplebased recording system is random access. Random access production refers to the fact that digital audio can be stored within a random access memory (RAM), or a disk based memory medium in such a way that the data can – virtually instantaneously – be accessed, processed, or reproduced in any order at any point in time.

Once developers began to design updated sample editor software, it was discovered that through additional processing hardware, digital audio editors were capable of recording digitized audio directly to a computer’s hard disk. These devices, sometimes known as digital audio workstations (DAW), serve as computer based hardware and software packages that are intended specifically for the recording, manipulation, and reproduction of digital audio that resides on hard disk.

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.

Continuing the audio effects series, again, we all know of audio effects and what they generally are supposed to do. They are used to manipulate audio in ways that are not available with traditional playing and recording techniques. If you’re like me, and enjoy dabbling in audio production, you’re probably familiar with all the basic effects and maybe some other types. Noise gate will be one of the topics of discussion today. Noise gate, what the heck is that? If that was your first reaction, you’re not alone. Please don’t worry; we will be demystifying this subject later on in the article. We will also be discussing flange, which is a more standard and widely used audio effect. So, in today’s article we will be discussing both noise gate and flange effects, how they work and why they work the way they do.

Noise Gate

Basically, noise gate is a device or software logic that is used to manage the volume of an audio signal, in recording studios and in sound reinforcement. They are also used by musicians, in a portable form, to control amplification noise. At its most simple form it controls noise by only allowing sound to pass through it at a certain set threshold. Think of it as a literal gate; when the gate is open sound can pass, when the gate is closed no signal is allowed through. More robust noise gate units have extra controls, I.E. attack, sustain, decay, release. This is so that you can further control the gating of your audio. Say you’d like to have the gate applied in a hard fashion, you would set a short attack and a short release, so on and so forth. Noise gates are often used to isolate background noise from live recordings in order to eliminate them from the final copy.

Flange

Flange is related to the phasing effect produced by a, well, phaser effects unit. It is produced when two identical signals are mixed together, with one of the signals time-delayed by a small and gradually changing amount. The amount is usually equal to or less than 20 milliseconds. Peaks and notches are produced in the combined frequency spectrum, related in a linear harmonic series. Part of the output signal is fed back in and resonates, intensifying the peaks and notches. This effect was originally generated with 3 three headed tape machines. Two of the tape machines would play the signal, obviously somewhat out of synch, and the third tape machine would record the output. The modern version of the effect is created using DSP (digital signal processing) technology.

This is the second part in my continuing series on audio effects. Today we discussed noise gate and flange, we’ll be moving on some more advanced effects later on. I hope that this helped you all understand the basic functionality of these two effects, ultimately making your next foray into audio editing a bit less intimidating.

Being a sound engineer can be quite exciting as almost all the areas they will work in are events that bring a lot of fun. As a professional, you will be involved in the recording and editing of audio to produce desired effects.

To be an audio engineer, you have to go to school and pursue the course and there are many audio engineering colleges offering such programs. This is the main reason you need them as you have to acquire the right knowledge, skills and certifications to be considered a professional. You will only be employed or find jobs if you can prove that you have undergone the required audio engineering courses and emerged successful.

Audio engineering has progressed over the years and one of the changes that are noticeable is the fact that people are now using the digital technology as opposed to analog technology. The good thing with these colleges is that you get a chance to learn both technologies especially the new techniques resulting from the latest technology and how to integrate them.

Client’s needs are ever-changing and as such every audio engineer must adapt to the changes to be able to meet the demands of the customers. You need to go to school to learn how to meet changing clients’ demands and most of the audio engineering courses are designed in such a way that you will find it easy to adapt to the changes in technology which results in people’s need for quality products.

There are many equipment used in audio engineering and the best place to learn them is at the audio engineering colleges. Most of the equipment are not very easy to use but under the right environment and with the right people, you can master them. After completing your studies, you can now purchase your own equipment for use in your work having learned how to use each of them.
