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.

Ratings and Reviews

Virkelig godt program

Jeg kan kun anbefale dette program
Jeg har bla brugt det til at få styr på lyden i en sal med mange mikrofoner som gav meget feedback
Med spektrogrammet kunne jeg se hvor rummet ringede i tonerne, og det efter dæmpe det lidt med en equaliser.
Syndes dog der mangler muligheden for at kunne summe ind på detaljer, eller at gemme data.

Utroligt meget for pengene...


Dette er helt klart en app hvor man får utroligt meget "value for money". Den har stort set alle det funktioner man kan ønske sig til audio-analyse. De eneste ting jeg ønsker mig er support for mic-profiles (f.eks. i436) og db SPL skala.
