Audio Signal Processing

Audio signal processing is a field that focuses on diverse techniques for intentionally altering sounds. These techniques are used in most musical applications. Audio signal processing deals with electronic manipulation of audio signals, which are electronic representations of sound waves. Audio signals can be represented in analog or digital format. Analog signal processors work directly…

Modulation Effects Part 1

Modulation effects are a type of audio effect that is capable of modifying sounds in a peculiar way.  Sounds can be altered by modulation effects by adding a time-delayed version of the sound itself while varying the size of that delay over time. Modulation provides a sense of dimension, motion, and depth to sounds. Modulators,…

Audio Formats And File Types

The audio universe has a wide variety of audio file types that can be classified under three main groups: uncompressed audio formats, lossless audio formats, and lossy audio formats. There are essential differences between compressed and uncompressed audio file types. Also, it is important to understand that some compressed or lossy audio formats discard audio…

Understanding Compression

Compression is the process of decreasing the dynamic range of an audio signal by boosting the lowest peaks and flattening the loudest peaks in the signal. Compression can turn a sound into a great performance or a total disaster. A compressor is a dynamic range processor that involves several parameters, including threshold, ratio, attack, release,…

Using Formants To Synthesize Vowel Sounds

A formant is a spectral shaping that is created from an acoustic resonance of the human voice tract. A formant is referred to as an amplitude peak in the spectrum of resonant sound sources. A formant is a concentration of acoustic energy that flows around a specific frequency in the speech wave. There are a…

The Unique Sound Of The Duduk

A duduk, also known as tsiranapogh, is an ancient double-reed musical instrument that is part of the woodwind family and it is made of apricot wood. This musical instrument, called dudukahar in Armenian, resembles a unique flute that sounds like a wailing voice. The duduk is typically played in pairs, achieving a richer and more haunting…

The Art Of Equalization

Equalizing is constantly evolving within the music production universe by using several audio plugins. Some plugins are instant balancers, which offer clarity, definition, depth and cohesion to sounds. Some plugins work automatically and manage to balance frequencies by themselves. Automatic plugins are capable of identifying which components of the frequency spectrum are looking for the…

Side-Chain Return Effects

Plain side-chain compression is a widely used technique by many producers. This technique is often applied to bass lines, as they tend to lower the volume of the bass, in order to let the kick drum through without altering the low end. Side-chain return effects are the result of excessively covering the overall audio signal.…

Sub Frequencies

Human hearing is not quite sensitive, so when a sound reaches a range below 20Hz, noises tend to be felt more than heard. Nowadays, thanks to the development of audio technology, it is possible, and useful, to add sub frequencies to an audio source. It is also possible to recover sub frequencies to certain musical…
