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).
Edit: Providing some context on what exactly I need to do.
I am using Wavesurfer.js. Say I have an audio file using 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?
I would suggest you to store your .txt file content into the ID3 metadata container. You can, for example, store it under
UNSYNCEDLYRICSfield.
