Faber Acoustical is pleased to announce the immediate availability of RoomScope for iOS on the App Store. RoomScope both measures and analyzes room impulse responses, calculating acoustical parameters such as reverberation time, early decay time, clarity and definition. Room acoustics parameters may even be calculated and displayed in whole or 1/3 octave frequency bands.

Some time ago, I was made aware of the i436 measurement microphone from MicW. It looked like exactly what was needed to turn any iOS device into a quality sound level meter, or acoustical analysis tool, that you could truly carry around in your pocket, but it was limited in its utility by that pesky low-end roll-off that plagued earlier versions of iOS.

Today, I had the opportunity to begin testing the audio input characteristics of the new iPhone 5. As seen in the plots, below, the headset input frequency response matches that of the iPhone 4S, which was presented in the previous post. The behavior of the built-in microphone also seems to match that of the iPhone 4S, suggesting that Apple kept the audio input path essentially unchanged in the new device.
