Phase Shifting & Time Delay

What is Phase shifting?   Phase shifting is essentially in the core of every audio filter or equalizer. For example, all-pass filters are the heart of phase-shifting effects. They can create an artificial stereo from a mono sound source. Flanging effect is...

Pseudo-Stereo Effect

Pseudo-stereo audio processing techniques generate two stereo channels from a single mono one, for the purpose of generating a wider spatial impression, while creating an illusion of multi-directional audible perspective. Moreover, you can use pseudo-stereo as a...

Sidechain Compression

  What is Sidechain compression?   Sidechain compression, also known as ducking, is an audio effect commonly used in radio and pop music, especially dance music. In sidechain compression, the presence of one audio signal reduces the level of another one. In...

Parallel Processing

Serial Processing   In audio processing, we can say there are two main ways of adding effects to a chain in just about any DAW. The first one works by basically interrupting the dry audio signal of an audio or software instrument.  You can do this by using the...

Gain Stage

Gain Stage 101   In audio engineering, the term Gain Stage refers to a point during the audio signal flow where an audio engineer can make adjustments to the level of the audio signal. The parameters for this kind of modifications are usually gain faders. You can...

Nonlinear Audio Processing

Nonlinear Systems   Digital signal processing is mainly based on linear time-invariant systems. The assumption of linearity and time invariance is for sure valid for a great variety of technical systems. Especially for the systems where input and output signals...
