Ultrasonic USB microphones
The first fully digital ultrasonic USB microphone.
Ultramics are ultrasound microphones, with an integrated digital to analog converter. To record or to listen ultrasound you only need an Ultramic and a host device such as a Windows, Linux, Apple PC or a smartphone or tablet.
There are different version with different sampling rate:
Ultramic192K, Ultramic200K & Ultramic250K with 192 KHz, 200KHz and 250KHz respectively sampling rate.
The USB 2,0 Full speed port allows an easy connection to any PC or Mac computer. The device is recognized as a standard USB audio microphone, so no driver installation is required!
It appears as a single channel audio input device. However, if recording in stereo, the two channels will appear identical.
The MEMS (Micro Electro-Mechanical Systems) microphone is very sensitive, with a good signal/noise ratio and small form factor.
Connect it to your PC, iPhone, iPad, Android smartphone or tablet, and it will immediately be recognized as a new audio input.
In your preferred sound recording software, simply select the new audio input, and choose the sampling frequency. Table below for device compatibility.
Ultramic can be easily opened, via a screw on the back. There are two switches, near the front of the microphone, that can be turned on and off with a fingernail (no tools needed), to change amplification between the three hardware levels.

The ultramic has been developed with the scientific support of:
CIBRA / University of Pavia.
It can be used by scientific researchers for:
– Detection and recording of biological ultrasounds for bioacoustic
studies on insects, rodents and bats.
– Environmental studies to assess the impact of wind farms on bats.
– Recording and analyzing mouse ultrasonic vocalizations for
– Detection of the high-frequency noises emitted by switching power
supply, by LCD screens, and also by the turbines of car and truck
In your home or in office: Discover the ultrasonic noise emitted by your TV, your computers, and by the power adapters of all your electronic devices.
Outside, use the UltraMic to record bat sounds! And discover the ultrasonic sounds of small rodents.
Amplification levels, can be adjusted by turning down one of the two switches on the inner board.

Tips & Tricks
Why is there a bad SNR on my Ultramic recordings?
In Windows OS the audio stream is resampled internally and digitally changed, this introduce a high gain and consequently higher noise.
To optimize the levels you must:
go to windows mixer
go to the Ultramic properties
Change the volume level to about 10
I do listen my voice!!! there’s something wrong!
Ultramics have no low pass filter so you can record at the same time ultrasound and audio.
At standard replay speed you can listen your voice and if you slow down the playback you can listen ultrasound!
