Spectrum Analyzers: Essential Tools in Music Production
Spectrum analyzers, long used in music production, have become essential tools for understanding and manipulating audio frequencies. These devices help pinpoint problematic frequencies, balance mixes, and even identify inaudible issues that can cause mastering issues.
A spectrum analyzer visualizes the frequency balance of a signal, displaying the amplitude of different bands across the hearable spectrum. This tool has been integral to digital audio workstations (DAWs) since their inception.
Today, spectrum analyzers are found in various VST plugins and audio effects, such as equalizers (EQ), providing a bird's eye view of a mix's frequencies. They help achieve overall balance and identify high frequency noise that may become distracting post-compression.
Five excellent spectral analysis plugins for use in your DAW include iZotope Insight, FabFilter Pro-Q, Voxengo Span, MeldaProduction MAnalyzer, and Blue Cat Audio FreqAnalyst. Notably, Voxengo Span is a free FFT spectrum analyzer plugin offering detailed frequency information and customizable modes.
Spectrum analyzers, with their ability to pinpoint problem frequencies and reveal extreme frequency issues, are invaluable in music production. They aid in reducing ringing effects, balancing mixes, and ensuring smooth translation to other systems. Many digital EQ plugins now include detailed analysis views to facilitate sound evaluation and EQ understanding.
