## What is Good Sound?

Make your sound more beautiful. Harmonic Audio Analyzer "Good Sound"

The piercing voice of a vocalist, or the sleek, seductive resonance of a saxophone—the secret behind that beauty lies in the "harmonics (overtones)" within specific frequencies.

"Good Sound" is an audio analyzer app that pinpoints and measures [harmonic components around 3000Hz (3kHz)], which the human ear perceives as the most pleasant and clear sound, visualizing just how richly your sound resonates.

Key Features
Real-Time Harmonic Scoring
Going beyond simple volume, our advanced algorithm analyzes the "ratio of 3000Hz components" relative to the overall sound balance. It rigorously rates the quality of your resonance on a score from 0 to 100.

Professional-Grade Frequency Spectrum
Deconstruct audio input from your microphone in real time using FFT (Fast Fourier Transform). Visually confirm if a vocalist’s "singer's formant" or the edgy, high-order harmonics of wind instruments are standing out.

Sleek Dark UI
A future-retro design that reduces eye strain and boosts your motivation, whether you are in a studio, a dark backstage area, or practicing at home.

Recommended For:
Vocalists & Singers:
Wanting to master a "resonance (formant)" that cuts straight through to the audience without getting buried in an orchestra or band.

Saxophonists & Wind Instrument Players:
Moving away from flat, lifeless sounds to craft a brilliant, centered, and rich tone that shines in jazz or classical music.

Voice Actors, Narrators, & Streamers:
Wanting to study the balance of a clear, attractive voice that reaches listeners' ears comfortably.

Start next-level acoustic training with your ears and "Good Sound."
