Your sound.
Your surroundings.
Keep your microphone in one place and listen at a comfortable volume. Give it at least 10 seconds of active sound; silence and clearly overloaded input do not build the profile.
Results describe sound captured by this microphone and environment. They are not laboratory speaker frequency-response measurements, a speaker rating or a calibration.
What does “Balanced” mean?
We average power density on a logarithmic frequency scale so wider bands do not win just by having more frequency bins. If one session band is at least 3 dB above the next strongest, it is dominant. Otherwise, we call the captured balance “Balanced.” This is a simple listening guide, not a certification or a claim of a flat speaker response.
Percentages describe the normalized captured balance, not the proportions of the original song. Music, microphone response, room acoustics, distance and browser processing all influence the result.
Audio and measurements stay in this tab. Nothing is uploaded or recorded. Stop or leave the page to release the microphone. Starting again clears the previous session.
