In particular, audio signal processing deals with electronic manipulation of audio signals, which are electronic representations of sound waves. They come in either analog or digital format. Firstly, analog signal processors work directly on the electrical signal, whereas digital ones work on the digital representation. We measure the energy contained in audio signals in decibels.…

“Modulation Effects Part 2” is a continuation of our first entry on this topic. In particular, modulation effects modify sounds in a peculiar way. Moreover, they can also alter sounds in a dramatic and bizarre manners. Many advanced effects have been available to the public for years, but recently, they’ve gained popularity especially in contemporary…

Modulation effects are a type of audio effect that modify sounds in a peculiar way. You can alter sounds with modulation effects by adding a time-delayed version of the sound itself while varying the size of that delay over time. In general, modulation provides a sense of dimension, motion, and depth. Modulators, also known as control…

Audio formats and file types are two concepts you’ll encounter throughout your music production journey. As a bit of context, the audio universe has a wide variety of audio file types classified under three main groups. These are uncompressed, lossless, and lossy. Just for starters, there are essential differences between compressed and uncompressed audio file…

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. It can turn a sound into a great performance or a total disaster. A compressor is a dynamic range processor that involves several parameters such as threshold, ratio, attack,…

Formants are spectral shapings created from an acoustic resonance of the human voice tract. These are amplitude peaks in the spectrum of resonant sound sources. Even more so, they are a concentration of acoustic energy that flows around a specific frequency in the speech wave. There are a variety of them and each one corresponds…

A duduk or tsiranapogh is an ancient double-reed musical instrument. It is part of the woodwind family, apricot wood being its material. Called dudukahar in Armenian, it resembles a unique flute that sounds like a wailing voice. One usually plays it in pairs because, in this fashion, you achieve a richer and more haunting sound. In…

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

Sidechain return effects are the result of excessively covering the overall audio signal. Here’s the explanation: plain sidechain compression is a popular technique amongst many producers. This technique is often for bass lines, as they tend to lower the volume of the bass. This results in letting the kick drum through without altering the low…

Nowadays, thanks to the development of audio technology, it is possible—and useful—to add sub frequencies to an audio source. Since human hearing is not that sensitive, when a sound reaches a range below 20Hz, audiences tend to feel the noises rather than hear them.Today, however, it is possible to recover sub frequencies to certain musical…
