iPrecisionMic is a precision, professional 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.
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.

iPrecisionMic + iPhone/iPad = Class 1 Instrument
Connect iPrecisionMic to any iOS device with a Lightning connector, download our AudioTools app, and you have a precision sound level meter, ready for certification.
Plug in the included AC adapter and charge the attached iOS device for extended run time.
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 is suitable for use outdoors in all weather conditions.
All of the active electronics are in the microphone body, including the regulated power supply, 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 will automatically unlock the SPL Pro and SPL Graph modules (including octave band logging) in AudioTools. Combined with the other free modules in AudioTools, RTA, FFT analyzer, SPL Meter, and Generator, you have a complete test & measurement package. Extend this with any of our optional modules, such as STIPA speech intelligibility or Smaart or LARSA for room correction and sound system setup.
iPrecisionMic is powered directly from the iOS device. It uses less than 60ma while audio is active, and much less when idle.
The microphone also includes a power input port designed for the supplied 5V 2.5A power supply. This power is fed to the iOS device so that you can run the entire system on AC power indefinitely, and even charge the attached iOS device while the microphone is plugged in.
To use the signal generator output from the app, just plug the audio cable into the headset jack after connecting iPrecisionMic.
Type 1 Certification
iPrecisionMic has passed 61672-3 Type 1 testing at West Caldwell labs.
We will have the following accessories available later this year:
- 20dB pad to allow extremely high SPL readings (148dBA)
- Weatherproof windscreen
- Weatherproof remote location mounting kit
