From a mobile phone video only sound?

And I have a couple of videos on my phone that I would need the audio on my own without the video. Is there any possibility? If that's important, I have Android, a Huawei phone.

If you can load it on the pc there's mp4 to mp3 converter

Download Audacity.

Since you can also pull in video files to load the soundtrack.

Then save as MP3.
