I am working on a web-based application (frontend: VueJS). The application makes use of blob files to store audios and videos. I have access to the blob in the frontend. When I try to download the blob files, everything works fine except there are no timestamps.

I have done a bit of researching and found that blobs by themselves do not contain metadata such as the total duration. I was wondering, how can I incorporate the duration metadata to the audio blob before downloading it?

I have tried using id3js but couldnt make it work for some reason(it shows ‘fs’ not found) [perhaps vue doesnt support it]. Can anyone provide any solutions on how to go forward with downloading the blob? I have reached the point of obtaining the duration through the use of certain libraries. I do not know how to go forward from there. Thank you very much!
