ABSTRACT
This chapter describes the most popular signal processors and effects, and suggests how to use them. Effects are available both as hardware and software or plug-ins. Plug-ins are the usual way to create effects in a computer digital audio workstation (DAW). Parallel compression effect blends compressed and uncompressed sounds of a track. A sidechain is an input signal to a compressor that controls its gain reduction. Chorus is a wavy or shimmering effect. The flanging effect varies or sweeps the delay between about 0 and 20 msec. Reverberation effect adds a sense of room acoustics, ambience, or space to instruments and voices. Some signal processors have a reverse reverb effect in which the reverb comes after the note that produced it but builds up before it fades out. Basically a delay unit with delay modulation, a harmonizer makes a variety of pitch-shifting effects. Multi-effects processor provides several effects in a single device or plug-in.
