Spectral Audio Analyzer is a free Android application developed by RadonSoft that allows users to display any type of audio from the microphone as a colored spectrogram. With an 8 kHz spectral bandwidth, users can identify environmental noise, search for annoying tones, view harmonic patterns of instruments and voices, and analyze the frequency range of their speaker in real-time.

The app is perfect for sound engineers, musicians, and anyone who needs to visualize audio in real-time. The intuitive interface is easy to use, and the app is completely free to download. If you encounter any bugs or have feedback to share, RadonSoft encourages you to contact them at
