Want to create audio editor with multiple audios using wavefurfer or wavesurfer multitrack plugin

[Haritsinh]

Hi all, firstly thanks @katspaugh for this amazing plugin, now I want to create audio editor like app in which there will be mutiple audios side by side one after another as we can see in most of the video editor, I just want waveforms of audios and one region for all of the audios, I have figured it out for single audio but single timeline and multiple audios freely draggable on the timeline which I want to do which is not seems possible from what I tried to found in wavesurfer example or docs.

It should have long timeline and all audios can be dragged on timeline anywhere, I have seen the Multitrack plugin of wavesurfer but it seems it is like remixing of audios or combining multiple audios into one instead of synchronous audios, I am attaching the image for reference of what I want to make, see the attached image and help me find ways to do that with wavesurfer only, or with any extra plugin of wavesurfer, any help will be appreciated, thank you in advance.

Option 1: start with wavesurfer-multitrack, and overlay tracks on top of each other using a negative top position. I briefly tested this and it seems to work fine.

Option 2: merge audio into one track with Web Audio, then load it into wavesurfer as a blob

I think option 1 is better, and I have also tried it, I need to add modifications, but I appreciate your help, thanks for guiding.
