I have a small personal mixer by my drumset. I have a mic set up to it and the rest of the house coming through my mixer. I want to record that audio to my phone so I can post videos. I want to record what I hear. Cant seem to do it. I bought a 3 ring aux cord. And have it running through a jack adapter from my mixer to my cell but my phone keeps recording off of built in mic. I want to be able to record video and sound of my drumming and the sound directly off my mixer.
