I was playing for some friends and it got me thinking about what my phone could do to enhance the experience. Oftentimes, you will be visiting friends and they pick up their acoustic guitar and ask you to play for them. However, there are challenges. For example getting a decent balance of vocal and instrument volume, and a lack of a drum track.
So it struck me that most of the tech to do that is in my pocket. Would it be possible to have an app that uses my little BT headset as a mic, and then had a built in drum track and the built in mic to grab the audio from the guitar. Then it could grab all those audio sources, perhaps even with some limited effects, mix them and play them on an external speaker.
Is that a crazy idea, or does something like that exist? I understand you aren't getting studio quality, but is it enough to enhance the experience in a buddy's living room?
