Hi there, very much a DIYer, I create lots of different Arduino-type projects, both for myself and acquaintances.
Here are a couple of projects I've incorporated audio into....
1. I call it the HBTY box, and it is installed in a sports bar/restaurant I do all the technical; stuff for. It has Line-In (from the Sky receivers), AUX In (for anything else), Bluetooth connectivity, USB stick (for playing mp3 files, and a special button for playing the owner's preferred "Happy Birthday to You" song from a MicroSD card when someone celebrates with a cake etc.
All controlled by a PT2134 4 into 1 audio processor module, under the watchful eye of an Arduino Nano. Source changes are all faded in and out, so it's a "proper job".
2. In the same venue, the house speaker system is used for the multiple screen sports, but they have recently installed a jukebox. It's a PITA for the bar staff to have to turn down the house system when they allow the jukebox to be played (some sports, especially football matches, take priority). I've built a detection box that can be fed from an unused speaker outlet on the jukebox, which will cause the house sound system to fade to zero as soon as it "hears" the jukebox playing, and fades it up again after a programmable silence period (inter-track delay). Although I should have used logarithmic digital potentiometer ICs, we can get away with linear, because the house system is either fully-on, or fully-off. It being a linear fade is noticeable, but not badly so...
I could go on some more, but that's enough of me boring you all...
