Since it will be mostly ultrasound, a bat-recorder may do this. A bat-recorder makes ultrasound hearable, but normally does not make a backup.

For which purpose do you need the sounds?

If you want to make the sounds visible for analysis, you need a good microphone with a frequency range into the domain of ultrasound and a (mobile) recorder. It exist a lot of programmes, which make the sound visible like on an oscilloscope.

The sounds of birds also have a range  into the ultasound, so an equipment for recording voices of birds may also fit.

This might help, or maybe give other contacts that could help.

Thanks to both. Indeed, I need to make sounds visible for an analysis of the patterns emitted by an insect. Your comments gave me a good idea.  Thanks you very much.

Do you know this article about ultrasonic hearing in moths? It deals with visualisation of sounds - sound production of moths is also mentioned:

 Thank you Rudolf , I'll check.

Hello Dear

The advent of electronic instruments(especially keyboards and synthesizers), effects and other instruments has led to the importance of MIDI in recording. For example, using MIDI timecode, it is possible to have different equipment 'trigger' without direct human intervention at the time of recording.

In more recent times, computers (digital audio workstations) have found an increasing role in the recording studio, as their use eases the tasks of cutting and looping, as well as allowing for instantaneous changes, such as duplication of parts, the addition of effects and the rearranging of parts of the recording
