<!-- SECTION: Summary -->
## What is Low Frequency Detector?

Low Frequency Detector is an acoustic measurement tool designed to identify low-frequency noise between 1Hz and 100Hz that is typically difficult for the human ear to perceive. The app utilizes 1/3 octave band analysis and FFT analysis to help users locate and quantify environmental noise sources like construction or industrial equipment. It provides technical data to assist users in identifying the frequency components and sound levels of their surroundings.

## Key Features

- **LF Level Measurement**: Measures low-frequency power levels below 100Hz using a flat characteristic with a one-second update interval.
- **1/3 Octave Band Analysis**: Provides detailed frequency component examination for low-frequency sound waves.
- **FFT Analysis**: Uses Fast Fourier Transform to visualize and identify specific frequency peaks in the noise environment.
- **Audible Band Leq**: Measures power levels within the standard audible frequency range using a flat characteristic.

<!-- SECTION: Target Audience -->
## Who is it for?

Individuals sensitive to environmental noise or those seeking to identify and measure low-frequency sound sources in their vicinity.
