I want to strip metadata from MP3 files.

In a brief: How to simply get a stream of pure MP3 frames out of a MP3 file – by means of command line tools? Preferable using tools out of the box of a linux mint system.

I found this thread. I wanted to use avconv and tried the given hints.

slhck's hint doesn't work simply by replacing ffmpeg with avconv. The output file has no more Title and Artist information, but embedded images are retained.

The same happens with evilsoup's hint, even albeit this is a native avconv hint. His second hint even retains Artist, Title, and so on.

OS is Linux Mint 17.

Commandline and output of avconv:

$ avconv -i in.mp3 -map_metadata -1 -c:v copy -c:a copy out.mp3

$ avconv -i in.mp3 -map 0:0 -map_metadata -1 -c:a copy out.mp3

Ref. comment – image is considered being a stream; the stream is deselected by only mention 0:0 as parameter to -map

In order to remove the metadata from the MP3 files you can use the below there tools

eyeD3, id3tool, id3v2

Example for eyeD3:

eyeD3 --remove-lyrics --remove-v1 *.mp3
