A USB microphone is a sensor that allows users to easily measure and record sound by simply connecting it to the USB port of a PC or smartphone. With an integrated A/D converter built into the sensor, digital signals are output directly through the USB interface.
The dedicated recording software (USB Microphone Recorder, free of charge) enables seamless data transfer to the O-Solution analysis software for further analysis.

Software (USB Microphone Recorder )

  • Software (USB Microphone Recorder )_01

This software is designed for USB microphones. You can operate it by connecting a USB microphone and a computer with a USB cable. It displays and records time waveforms, and saves the recorded data to a specified folder.

Seamless integration with O-Solution analysis software
The dedicated USB microphone recorder enables smooth data transfer to O-Solution for efficient analysis.

  • Software (USB Microphone Recorder )_02

Features

Triggered Recording Function

Recording can be started automatically when the input signal exceeds a specified sound pressure level.
The software also features the "Pre-Recording Function", which allows recording to begin several seconds before the trigger event occurs.
This makes it possible to capture sounds even before an abnormal noise is generated.

Automatic Repetitive Recording

Using the trigger function, recordings can be automatically repeated for a preset recording duration.

Case Study

Motor noise

Automatically records sounds when an abnormal noise is detected—for example, repeatedly capturing abnormal noises generated by motors.
