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...

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...

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...

Step Sequencer

What is a step sequencer?   Step sequencers were originally hardware modules. They produced a limited number of control signals in a steady, pulsed sequence that kept repeating until deactivated. The output of the signal could be sent to some other synthesizer...
