Audio input may be acquired via the built-in microphone or an external measurement microphone. For best results we recommend using a calibrated measurement microphone connected via USB audio interface or iPhone dock connector. This allows for high precision and flat frequency response, as well as for stereo input.

Genau das, was ich gesucht habe


Wunderbare App, mit sehr guter Darstellung des Frequenzspektrums, Frequenzgenerator ist auch mit dabe. Was will man mehr. Die App läuft bei mir auch stabil.

verdient mehr aufmerksamkeit !!!


dieser analyzer ist ausgezeichnet!
ich hab ihn eher aus neugierde mal gekauft und bin beeindruckt.
die umsetzung der anzeige ist sehr praxisnah und angenehm.
nichts zappelt lästig herum und doch schnell genug, um auch kurze impulse zuverlässig zu zeigen.
die einstellungen sind ausreichend und schnell zu erreichen.

vielen dank für ein hilfreiches und dabei günstiges werkzeug!
