Harmonicity Meter

Harmonicity Meter enables you to measure the harmonic to noise ratio, known as harmonicity, from your device's microphone. This metric reflects the sound energy in harmonics compared to the total spectrum. Utilized effectively for assessing sound purity, higher harmonicity values signify clearer sounds. It is important to note that Harmonicity Meter is best used with continuous and consistent sounds such as vowel pronunciations or steady tones from speakers or instruments. Variable sounds may result in inaccurate outputs.

Key Features and Measurements

This app focuses on providing a range of acoustic measurements: harmonicity, jitter, and shimmer. Jitter measures the frequency variation, while shimmer assesses the amplitude variation, both relative values presented as percentages for clarity. Harmonicity Meter auto-detects sound and initiates measurements upon detection, ensuring a smooth user experience. The app's averaging function stabilizes the data by collecting consistent measurements over time.

Sensitivity and Unique Capabilities

The effectiveness of Harmonicity Meter can vary based on the proximity of the sound source to the microphone and the microphone's sensitivity across frequencies. It is constructed with a fast Fourier transform for creating a frequency spectrum, which is instrumental in determining both harmonic and noise energy levels. Additionally, it offers a musical note conversion feature that helps musicians tune their instruments.

User Experience and Range

The app is equipped with user-friendly functions such as a pause button for noisy environments and an autoscaling intensity spectrum display between 0 and 2 kHz. It reliably detects fundamental harmonic frequencies within the range of 100 Hz to 2 kHz, making it a versatile choice for both casual and professional users seeking to analyze sound purity. Harmonicity Meter caters to users interested in detailed sound analysis supported by a robust technical framework.
