TurnMeUp lets you listen to music and talk at the same time. You and a friend can run a voice connection in the background while you each listen to music, and when someone speaks, the music volume adjusts automatically. Now you can talk without taking your headphones off when you go for a run together, are hanging out together, working together, or for any other reason.
You can also use this app by yourself with "alone mode". This will let you listen to nearby sounds when you have your headphones on, like somebody speaking next to you, a car horn, a siren, or anything else. Settings help you choose how loud sounds need to be before you hear them, when you hear people, and how much your music volume adjusts when talking. More features and automation coming soon.
This app is meant to be used with headphones, and works better with an inline microphone.
