I would like to build a music player / device for an older person, not tech savvy user.
I have the MP3s on my linux desktop/laptop, but not all the metadata and cover art.
I’ve worked with RPi before, jailbreaking iPhones and roku. So I have some limited experience with small devices.
I’m wondering if I could obtain some kind of old/used android phone, remove all the apps so the home screen is completely empty, transfer via USB or ssh/scp the MP3 files (and metadata + cover art), then have some kind of music player app which would be the only app on the phone/device.
Then shutdown any wifi or internet connectivity, but still allow bluetooth to pair with an external speaker.
Bluetooth, while being perfectly adequate, does need to compress/encode the audio. As a result, wired does sound better, though it only really makes a difference if you’ve got headphones where you might notice it.
Oh okay. That, I understand. I thought that incorporating bluetooth also compromised the sound quality of the wired output as well.
