Question

In Node.js, how to get the audio duration of an audio file in Google Cloud Storage without downloading?

Answer 1

When looking at the documentation I didn't see anything about checking the file contents, let alone something as specific as calculating the duration of an audio file, so: cannot be implemented .

At a minimum (depending on the file format), you'll need to download enough of the file to read its embedded metadata (I don't see any mention of support for content ranges , so you might Need to get the entire file).
