Effects processing refers to the manipulation of audio signals to enhance or alter their sound characteristics. This can include adding effects like reverb, delay, or distortion to create a desired atmosphere or texture in music. By using effects processors, musicians and sound engineers can shape the audio to fit specific styles or moods. In digital audio workstations (DAWs), effects processing is often applied through plugins that can be adjusted in real-time. These tools allow for precise control over parameters, enabling users to experiment with different sounds and achieve unique results. Overall, effects processing is essential for modern music production and sound design.
