Unable to descrypt mp3 file via gpg

Question

I'm trying to decrypt a binary/mp3 file of 100Mb of size.

gpg2 --decrypt my_audio.mp3.gpg

And it results into a long binary text in the terminal and it won't create a pure mp3 file:

binary text

What's wrong with it? How can I decrypt the file?

Answer 1

That is the mp3. Try this

gpg2 --decrypt my_audio.mp3.gpg > my_audio.mp3

Answer 2

From the man page:

--decrypt
-d
Decrypt the file given on the command line (or STDIN if no file is   
specified) and write it to STDOUT (or the file specified with --output). 

So use either

gpg2 --decrypt my_audio.mp3.gpg > my_audio.mp3

or

gpg2 --decrypt --output my_audio.mp3 my_audio.mp3.gpg
gpg2 --decrypt -o my_audio.mp3 my_audio.mp3.gpg
