I have been having some trouble with backpack studio, not able to duck music or sounds while I am speaking into a microphone. And, sadly, I know that backpack studios for the most part nonexistent and has no support. So, I am looking for something similar That will allow me to mix sound and or music and speech on the go. I have seen an app called podcast studio, but I really don’t have $20 a month to spend on such a thing. Any help would be much appreciated.
