The Basics of Audio Distortion

Due to the importance of this topic, here are the basics of audio distortion. To begin with, distortion is any deviation that mimics an audio waveform between two points in a single path. Unwanted distortion usually comes from an extremely strong signal. When an audio signal level is too high, it loses some of its…

Audio Processing

Audio processing, sometimes called “processing sounds,” means changing the characteristics of an audio signal. One can use this strategy to create new sounds, improve audio, fix sound issues, and separate audio sources. In addition, it is a means to compress, store, and transmit audio information. The most common types include equalization, compression, expansion, limiting, reverb,…

Audio Filters

Audio filters are electronic circuits whose design either amplifies or attenuates specific frequency range elements. This removes unwanted from the audio signal, enhancing the tone of the output. They are essential in any audio system, but people also use them widely in both audio electronics and telecommunications. Types of Audio Filters: Various Classifications Equalizers and…

Audio Signal Processing

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

“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 (Part 1)

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

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

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: Synthesize Vowel Sounds

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…

Duduk

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…
