Real-time audio frequency spectrum analyser with high resolution, logarithmic frequency display, and spectrogram history — one of the highest-quality free audio analysis tools available on Android.
Spectroid displays a real-time frequency spectrum from the device microphone with high frequency resolution across the full audible range and into the infrasound region (below 20Hz on capable devices). The scrolling spectrogram view shows frequency content over time, making it possible to identify recurring audio patterns. Widely used by engineers, musicians, and researchers as a legitimate acoustic analysis tool. Free and open source.
