Understanding Frequency Analysis
Frequency analysis is essential for anyone working with audio, from DJs and producers to sound engineers and podcasters. By visualizing the frequency spectrum, you can identify which frequencies are too loud or too quiet, spot unwanted resonances, and make informed EQ decisions.
Our free frequency analyzer online displays the full spectrum from 20Hz to 20kHz — the entire range of human hearing. Low frequencies (bass) appear on the left, while high frequencies (treble) appear on the right. The height of each bar shows how much energy is present at that frequency.
Use this tool to analyze your mixes, identify frequency clashes between instruments, or simply learn more about the audio you work with. Combined with our BPM Finder and Key Detector, you have a complete audio analysis toolkit.
