File extension for Audio file with ID3 version 2.4.0, contains:MPEG ADTS, layer III, v1, 192 kbps, 44.1 kHz, Monaural

I got a audio file without file extention. I want to add file extention in that file. I just know that its a audio file. So I tried to check its type using file command.

alok@alok-HP-Laptop-14s-cr1:~/Downloads$ file AUD-20200501-WA0004.
AUD-20200501-WA0004.: Audio file with ID3 version 2.4.0, contains:MPEG ADTS, layer III, v1, 192 kbps, 44.1 kHz, Monaural

By seeing this output I am not able to find suitable file extention. I guess it can be mp3 file. Please tell what extention should I give to this file?

Double check with ffmpeg :

ffmpeg -i /the/audio/file
