Ionic App - Adding and mixing audio files to a video

I have recently started to use Ionic and I am developing a simple multimedia Ionic app.
I want to add sound effects to a recorded audio (client side).
After this, i would like to add the mixed audio to a video.

For the audio mixing i have two options :

  • Mix both files into one (prefered)
  • Play both audios synchronized

I did some digging on documentation and foruns but everything i’ve found was not very helpful.
