mimigar KEEN specializes in measuring sound pressure in the 18–20kHz ultrasonic band. It supports external microphones such as the Dayton Audio iMM-6C, incorporating calibration data for accurate SPL measurements.

Features

  • 18-20kHz band measurement
  • External USB microphone support (Dayton Audio iMM-6C)
  • Calibrated SPL display
  • Band-pass filtering

Platforms

  • Android (In Development)
  • iOS (In Development)

Settings & Calibration

Settings

The settings screen allows you to load microphone calibration data and perform SPL calibration.

Calibration Data

Enter the serial number of your mimigar microphone (e.g., CMM31808) and download to automatically load Evixar-calibrated data. This enables accurate SPL measurement without pistonphone calibration.

Calibration Data Loaded

SPL Calibration (Pistonphone)

For more precise calibration, you can perform SPL calibration using a pistonphone (1kHz, 94dB SPL).
