## Description

SimpleFFT is a lightweight and easy-to-use real-time Fast Fourier Transform (FFT) analyzer focused on the low-frequency audio spectrum. Utilizing the built-in microphone on your smartphone, SimpleFFT enables instant audio analysis without requiring any external attachments. The app displays temporal waveforms and performs frequency analysis, making it ideal for equipment failure diagnosis, scientific education, voice analysis, and musical instrument tuning.

Key features include a sample rate of 11025Hz, mono 16-bit audio format, 2048 FFT points with a Hamming window, and a linear horizontal frequency axis. The interface is fixed in landscape mode and automatically adjusts display sizes based on the device. Users can smoothly adjust the frequency range up to 5 kHz by dragging the screen. Additionally, the app supports installation to SD cards (for versions 2.2 or higher). A professional version named SoundAnalyzer is also available on Google Play for advanced functionality.
