Spectroid is a real-time audio spectrum analyzer with reasonable frequency resolution across the the entire frequency spectrum.
Sauberes Design, keine Werbung, funktioniert schnell und zuverlässig. Ein umfangreiches Menü erlaubt viele Einstellungen bez. der Darstellung der Skalen. Die Mikrofonqualität des Telefons ist bestimmt ein einschlägiger Faktor für die Erfassung; auf meinem Gerät jedenfalls zeigt Spectroid präzise alle Frequenzspitzen aus der Umgebung an.
