How to read an acoustic spectrum analyzer
The horizontal axis shows frequency (in Hz, MHz, or GHz), and the vertical axis shows amplitude, which is the power or strength of each signal (typically in dBm). Learn professional techniques for reading frequency spectrums, identifying resonances, fixing frequency masking, and achieving balanced, commercial-quality mixes. It displays the magnitude of various frequency components within an audio signal, providing a graphical representation of sound energy distribution across the frequency range. This tool helps you visualize sound by breaking it down into its individual frequencies: Start Analysis: Choose "Start Mic Analysis" for live microphone input or "Upload Audio File" to analyze a file.
