Chapter 7. Processing and Effects


If you're new to recording music, you might be surprised by the extent to which even a natural-sounding vocal on the radio depends on the arsenal of software and hardware devices known as effects. Whether you're trying to fix problems, "sweeten" recorded tracks, or send your listeners on a sonic roller -coaster ride, you'll need to master digital audio signal processors . This type of processing is usually handled by plug-in programs called effects.

Essentials

Processing and Effects

In this chapter we'll discuss:

  • What signal processors are

  • How to apply non-realtime signal processors and route real-time signal processors

  • Equalization and frequency: filter types and uses

  • Dynamics processors and amplitude

  • Time- related effects: delays and reverbs

  • Specialized processors: distortion, modulation, and utility

Essential Terms

  • Signal processor, filter, effect

  • Non-destructive and destructive editing

  • Routing: channel strip; insert/send/return/bus; side-chaining

  • Equalization (EQ): highpass , lowpass, bandpass filters, parametric/graphic EQ

  • Filter parameters: cutoff frequency, center frequency, bandwidth, Q/ resonance , stopband, passband

  • Dynamics: compressor/expander/limiter/gate/de-esser

  • Time: delay, echo, reverb

  • Convolution, impulse, impulse response (IR), Fast Fourier Transform (FFT), fuzz/overdrive/distortion

  • Modulation: tremolo, vibrato, chorus, flanger , phaser , ring modulation, low frequency oscillator (LFO)

Where to Start

Using your own audio software or one of the DAW/host demos included on the DVD, try out some effects, especially parametric EQ, dynamics processors, and delay/reverb. See p. 210 for some ideas.
