Combine an audio and a text file as one single file

[ManimMadhav]

Is there a way to combine an audio file (either .mp3 or .wav) and store some text information in a .txt file and save it as one single file (in which format such a file would be, I am not sure).

What I mean is, say I have an audio file in which I want to make regions. Those regions are stored in a text file which contains 3 values, i.e start and end times of regions in the audio along with a label for the region. I want to store the information in the text file saved with the audio in a manner that when a user loads an audio file using wavesurfer.load(), the regions get created automatically. How can i do so? Is this even possible?

Wavesurfer doesn’t do this by default but you can save your regions as a JSON and re-create them on load.

hey @katspaugh, thanks for your response.
I have tried and tested this way of storing regions in a JSON file and then imported it. the issue with this is that it gets tougher to manage when the number of audio files a user uses increases. Hence, is there a way i can store this information in the audio file (for eg. in it's ID3 metadata container) itself?

I don't know. If you find a way to do it, please share here.
