Audio mixing - any thoughts


I am newcomer to ionic development, and want to developing an app to mix two sounds and save to the drive. And I should be able to play the mixed sound afterwards. My flow is like this, 1) record audio from microphone. 2) mix the audio got from step 1 with a sound file. 3) Play the mixed file.

I don’t come across an inspiring example or demo to do these or similar things using ionic framework.

Any thoughts on how to go further is appreciated.
