The Ultramic384K is a high quality, professional digital device that can work as:

  • an USB ultrasonic microphone
  • and as a smart autonomous full spectrum recorder

The Bluetooth connection is used only for an easy configuration of the microphone if used as autonomous recorder. The ultrasonic transfer is done via USB.

The Ultramic384K BLE has an integrated analog-to-digital converter able to achieve a 384 kHz data sampling rate. The USB 2.0 full speed port allows an easy connection to a PC, iOS, Android smartphone or tablet and embedded Linux systems. The Ultramic384K BLE is composed of a main body with digital and differential analog amplification, a waterproof, high performance audio and ultrasonic microphone with a FG sensor, and a preamplification circuit. The ultrasonic sensor can be replaced with other sensors such as an infrasonic microphone, a vibration sensor, or a hydrophone. When used with an external USB battery, the Ultramic384K BLE's low power, integrated 32 bit microcontroller makes it the perfect device for long term autonomous recording.

Features

  • The Ultramic384K BLE is a high performance – omnidirectional audio and ultrasonic microphone
  • USB 2.0 full speed connection using a driverless – standard audio class UAC 1.1 interface for an easier communication with host devices
  • Hardware amplification gain is settled via two switches
  • Easy disassembly to access the SD card slot, the backup battery, the preamplification switches and button.

 

Applications
The Ultramic384K BLE can be used in scientific research for: Bioacoustics and Industrial research:

  • Detecting and recording of biological ultrasounds for bioacoustics studies on insects, cetaceans, rodents, and of course bats.
  • Environmental studies to assess the impact of wind farms on bats.
  • Recording and analyzing mice ultrasonic vocalizations for pharmacological studies.
  • Soundtracks and special effects (such as slowing down the recorded ultrasounds).
  • LEAK detection
  • Predictive motor fault monitoring
  • Detection of high-frequency noises emitted by switching power supplies, LCD screens, or the turbines of car and truck engines, energy saving lamps.
