Mix microphone input while playing music
Hi everyone! This might seem an easy question, but I can't figure out how to do it on my iPhone 13. My setup: I have a typical bluetooth speaker and a bluetooth microphone (those that come with a USB receiver), which separately work both fine. Now, what I simply want to do is play some song and at the same time speak over the microphone. My voice should be mixed in the song. I don't need to be able to record it or fancy controls beyond volume. I intend to use this "feature" for teaching music classes and being able to be heard by my students. Is there a simple mixer app or even better, an integrated way of doing this in iOS?
Thanks in advance!
