A common request for RoomScope has been to directly capture room impulse response (IR) data using impulsive noise sources, such as balloons or starter pistols. RoomScope 1.3 now supports both single-channel and dual-channel IR data acquisition. -> read more … Have you been looking for a tool to measure the reverberation time, early decay time, clarity and definition of a listening room, auditorium, or concert hall on your Mac? With version 3.2 of Electroacoustics Toolbox, the search has come to an end. -> read more … RoomScope 1.2 and IOScope 2.3 arrived in the iOS App Store this week. Both apps now support impulse response measurements up to 16 seconds long and use double precision (64-bit) FFTs in their measurements. -> read more … Although SignalScope Pro does not include the Dual FFT Analyzer tool, found in Electroacoustics Toolbox, it is still equipped to perform basic frequency response measurements. This tutorial focuses on using SignalScope Pro’s FFT Analyzer and Signal Generator tools to measure the frequency response of your audio interface. -> read more … One of the most powerful tools in Electroacoustics Toolbox is the Dual FFT Analyzer, which is capable of measuring system transfer functions and even indicating the quality of the measurement. -> read more … RoomScope version 1.1 for iOS is now available for download on the App Store. -> read more … 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. -> read more … Since the Lightning to 30-pin adapter arrived yesterday, I have had the opportunity to test several audio accessories with the iPhone 5. The results are presented below. -> read more … 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. -> read more … |
