Range & measurement details
RGB height preserves sample min/max peaks (±1 full scale); colored layers show the relative share of four non-overlapping FFT-bin power regions per channel with square-root compression. Components below −80 dBFS or 40 dB below the strongest band are suppressed for color only; measured band levels remain unchanged. The colored layers are a composition display, not separately filtered wave amplitudes. Color resolution is set by the FFT window and hop, not by waveform zoom. Band bars show integrated regional power in dBFS. The spectrum uses dBFS per FFT bin; it is not LUFS. Range spectrum is recalculated only when selection ends. Whole-track server meters remain unchanged. *Frequency range ends at the lower of 20 kHz and Nyquist.

Average frequency spectrum
Reanalyze your track to generate its spectrum.
How to read the spectrum
Time-averaged FFT power across both channels. Frequency runs logarithmically from 20 Hz to 20 kHz; 0 dB is this curve’s highest point, not absolute loudness. Bass, midrange and high-frequency peaks show tonal balance. This does not diagnose masking between instruments or guarantee mix quality.

How to read this image
A narrow vertical image indicates similar channels. A wider cloud shows more stereo difference; points beyond the L/R diagonals can indicate phase cancellation. Listen in mono as well. Sampled across the track, with a shared visual gain for both axes.

About these measurements
A note on what this is: these are measurements, and the explanations above only describe what was actually measured — nothing here is invented or guessed. Automated mastering (below) is a fast, measurement-driven starting point; it's not a substitute for a mastering engineer's judgment, and we don't market it as one.

See all free toolsHow to use the quick analysis
This is the fast first look. Use the waveform to spot where the track changes, the spectral balance for the overall tonal picture, and LUFS and true peak for level. When you want to inspect a specific section or frequency region, open the same file in Audio Analysis Studio. Use the waveform to inspect transients and the frequency bands to locate changes in bass, midrange and treble over time. The audio spectrum analyzer shows whole-track tonal balance; LUFS and true peak describe level. Compare similar material at matched loudness before deciding what to change.

Is the audio analysis free?
Yes. Upload a supported file to inspect its measurements. Adaptive Mastering is a separate paid step; analysis does not require buying a master.
Why can a selected range differ from the overall result?
The selected range updates the local FFT spectrum and its four frequency regions. Loudness, true peak and the whole-track server meters still describe the complete uploaded track.
