How can I add metadata on audio files?

Question

I have audio files that I want to share with an open data license, but before doing that I want to add metadata. How can I do it with an open source language?

Answer 1

Use ffmpeg and the metadata framework. Documentation can be found at: http://ffmpeg.org/ffmpeg-formats.html#Metadata-1

There is also a node package available for manipulation of metadata: https://www.npmjs.com/package/ffmetadata

Answer 2

Soundminer is very popular.

Here's a nice tutorial for that.
