Track Summary shows the average spectrum across the recording.
A spectral peak shows energy near a frequency. It does not establish a track’s musical tuning or therapeutic effects.

The Solfeggio Frequency Visualizer is a free online audio frequency analyzer that lets you see which frequencies are present in your music or sound recordings.
Upload an MP3, WAV, FLAC, or M4A file to explore its frequency spectrum, identify prominent frequency peaks, and highlight individual Solfeggio tones such as 528 Hz, 396 Hz, or 963 Hz.
Unlike a simple audio waveform, which shows changes in sound amplitude over time, a frequency spectrum displays how audio energy is distributed across different frequencies.
Whether you’re exploring meditation music, working with sound-healing recordings, or checking a specific frequency, the visualizer helps you understand what’s happening inside your audio.
What Can You Do With This Tool?
-
Visualize audio frequencies
See an interactive frequency spectrum showing low, midrange, and high-frequency energy in your audio recording.
-
Highlight Solfeggio frequencies
Select 174, 285, 396, 417, 528, 639, 741, 852, or 963 Hz to highlight that frequency on the graph while dimming the surrounding spectrum.
-
Check for 528 Hz and other specific tones
Look for noticeable peaks near your selected frequency and see how strong they are compared with other frequencies.
-
Analyze the entire recording
Switch to Track Summary to view an averaged frequency spectrum across the audio file, rather than analyzing just one moment.
-
Watch frequencies during playback
Use Live Playback mode to see how the spectrum changes as your music plays.
-
Zoom into frequency ranges
Explore the full audio spectrum or focus on a narrower frequency range to inspect individual peaks more closely.
-
Analyze custom frequencies
Enter any supported frequency in Hz to highlight its position on the graph, even if it isn’t one of the Solfeggio presets.
-
Explore sample audio
Try a pure 528 Hz tone, 528 Hz meditation music, or regular relaxation music to see how different recordings appear in the frequency spectrum.
How to Use the Solfeggio Frequency Analyzer
-
Upload your audio. Choose an MP3, WAV, FLAC, or M4A file up to 100 MB and 10 minutes, or load one of the provided sample recordings.
-
Choose a frequency. Click a Solfeggio preset, such as 528 Hz, to highlight it on the frequency spectrum.
-
Explore the graph. The selected frequency range is highlighted while the rest of the spectrum is greyed out, making it easier to compare its strength with other frequencies.
-
Check the results. Look at the measured peak, its signal level in dBFS, and the frequency strength indicator.
-
Change the view. Use Track Summary for an overview of the entire recording, or Live Playback to observe frequencies as the audio plays.
You can also enter a custom frequency or change the zoom level to examine a particular section of the spectrum.
Understanding the Frequency Spectrum
The frequency chart displays two important measurements:
Frequency (Hz)
The horizontal axis shows sound frequencies measured in Hertz (Hz). Lower frequencies are associated with bass and rumbling sounds, while higher frequencies represent treble, hiss, and other high-pitched components.
Signal Level (dBFS)
The vertical axis shows the relative digital signal level of each frequency component. Peaks closer to 0 dBFS indicate stronger spectral components.
A tall, narrow peak represents concentrated energy around a particular frequency, while a wider distribution of peaks is typical of complex sounds such as music.
What Does Strong Peak or Weak / Inconclusive Mean?
The analyzer indicates how prominent the detected frequency peak is.
-
Strong peak
A noticeable spectral peak is detected near the selected frequency.
-
Weak / inconclusive
The selected frequency region does not contain a sufficiently distinct peak to support a confident identification.
These indicators describe the frequency spectrum, not the effectiveness or therapeutic properties of the recording.

Frequently Asked Questions
Can I Check If My Music Contains 528 Hz?
Yes. Upload your audio and select the 528 Hz preset. The analyzer highlights that frequency and shows whether a prominent spectral peak appears nearby. A peak indicates frequency energy, but does not necessarily prove that an intentional 528 Hz tone was added.
Can I Check All Nine Solfeggio Frequencies?
Yes. The visualizer includes presets for 174, 285, 396, 417, 528, 639, 741, 852, and 963 Hz. You can select each frequency individually to inspect its position and strength in the spectrum.
Can I Analyze Frequencies Other Than Solfeggio Tones?
Yes. Use the custom frequency field to enter a frequency in Hz and highlight it on the chart. The visualizer can be used for general audio frequency analysis, not just Solfeggio recordings.
What Is the Difference Between Track Summary and Live Playback?
Track Summary displays an averaged frequency spectrum calculated across the recording, providing an overview of its frequency content.
Live Playback shows the spectrum around the current playback position, allowing you to observe how frequency energy changes as the music plays.
Averaging can reduce the visibility of brief tones, so examining both views may help you understand the recording.
Can This Tool Determine Whether Music Is Tuned to 432 Hz?
Not reliably. Detecting a spectral peak near 432 Hz is different from determining whether a song uses A4 = 432 Hz musical tuning.
Musical tuning analysis requires examining relationships among musical pitches rather than checking for a single frequency.
Why Does the Detected Peak Differ Slightly From My Selected Frequency?
Differences can result from FFT frequency resolution, signal processing, musical harmonics, and the actual frequencies in the recording.
For example, selecting 528 Hz may reveal a nearby peak at 526.9 Hz. This indicates spectral energy near the target, not necessarily a mathematically exact 528 Hz tone.
Can I Analyze MP3 and WAV Audio Online?
Yes. The tool supports MP3, WAV, FLAC, and M4A audio files within the specified file size and duration limits, subject to browser decoding support.
