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 …

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 … 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 … This exciting improvement to iOS 6 will significantly improve the quality of acoustical measurements that can be made by using the iPhone, iPad, or iPod touch without requiring a dock connector accessory for audio input. -> read more … Now that I have my hands on the new iPhone, I thought I would go ahead and report on the state of audio I/O on the new device. -> read more … “Which devices work properly with the iPad?” In the table below, I list the devices I have tested with the iPad, along with some observations. -> read more … It turns out that in some ways, getting audio signals into the iPad is similar to getting audio signals into the iPhone 3GS, and in some ways it’s not. -> read more … Alesis finally got around to making shields for securing an iPhone or iPod touch to the ProTrack stereo iPod recording device. -> read more … With the advent of sound level meter apps for the iPhone OS (of which SoundMeter was the first) people began to ask, “How flat is the frequency response of the iPhone’s microphone?” Early testing indicated that the built-in microphone of the original iPhone was not a good candidate for sound level measurements, but that -> read more … Getting audio signals into and out of an iPhone OS device can sometimes be a bit tricky. The information presented below outlines the available means for getting audio signals into and out of each iPhone OS device. Available Input Routes … Available Output Routes … -> read more … |
