Audio attachment file format not supported

[Nithish 0]

Hello.

I shared an audio clip from whattsapp to Evernote. In Evernote the audio clip is saved as an attachment with extension (.opus) 

It is 7kb 

When I trying to open the audio attachment its screening as (not supported format) try apps from Google play to support this format.

How can I get the audio clip. 

If there is any app which supports the format please tell.

Help me Evernote!
