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.
The newest iPod nano does have Bluetooth. Not sure if 16 GB counts as “less space than a nomad” though.
Some very dedicated modders have managed to squeeze bluetooth into their Classics. Personally, I think that undoes the point of having one of the best sounding DAPs, but all power to them for adding some versatility.
Why would having bluetooth affect sound quality?
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.
