## N-Signal / FFT Sound Analyzer Description
N-Signal helps you visualize sound in real time.
It measures sound pressure (dBSPL) and analyzes digital frequency levels (dBFS) with precision.
Helpful for adjusting PA systems, testing stage sound, or improving room acoustics — whether in studios, churches, or classrooms.

* Key Features
- Real-time audio spectrum with FFT analysis
- dB SPL sound pressure level meter (mic input)
- Digital frequency analyzer (dBFS scale)
- Smooth graph motion optimized for live performance
- Supports dark modes
- Designed for musicians, engineers, and sound enthusiasts

N-Signal isn’t a laboratory-grade instrument, but a reliable audio reference tool for daily sound checks and education.
