iPrecisionMic is the only Class 1 (Type 1) certified microphone that is also an iOS direct-connect Lightning accessory. iPrecisionMic is factory calibrated to +/-0.1dB using a NIST traceable pressure-compensated calibrator. The calibration offsets are store in the microphone's nonvolatile memory, and are transferred automatically to an iOS device running our AudioTools app.
Available both with and without a Class 1 Calibration Certificate.
All of the active electronics are in the microphone body, including the microphone preamplifier, precision 24-bit A/D converter, and the circuitry required to communicate with Apple devices via a digital audio link. This means that we are not reliant on the analog electronics stages in the iPhone or iPad, but rather we completely bypass them with a digital audio link.
iPrecisionMic can be powered directly from the iOS device. It uses less than 60ma while audio is active, and much less when idle. Alternatively, plug in the included AC adapter and charge the attached iOS device for extended run time.
Thus, not only is iPrecisionMic accurate, clean, and calibrated, but it requires no setup when connected to our apps. Instant, calibrated SPL measurements. Share it between several users, confident in knowing that it will also give you the same calibrated, reliable results no matter who is using it.
The microphone is built of beautifully finished nickel-plated solid bronze tubing, with no seams or welds. It has very low susceptibility to mechanical resonances. When equipped with a weatherproof windscreen and a protective boot on the cable end, it may be used outdoors in all weather conditions.
iPrecisionMic will automatically unlock the SPL Pro and SPL Graph modules (including octave band logging) in AudioTools.
