Audio difference between slacker and bluetooth

[lmaccaro]

Has anyone else noticed a pronounced difference in audio quality between bluetooth and internal sourced music like slacker?

My bluetooth sounds like it is playing underwater on the 3. Source is spotify on high quality downloads.

I have an S also and bluetooth sounds great in the S.

I also tried my wife's phone and bluetooth also sounds bad from hers.

I have the same issue.. Looking for some insight from the group here. I've tried making some changes to the bluetooth settings on my phone, but haven't noticed any difference.

iPhone or android?

Is your Bluetooth source compressed? I believe the built in Slacker app has a very high bit rate which helps to make it sound great.

Quite the contrary- the built in slacker app in the 3 is low bitrate (64kb/sec)

It sounds "fine" until you compare it to high quality stuff like 320kb/s MP3s or uncompressed FLAC from a USB key.

Yes same issue with my phones and playing music on Bluetooth. Sounds much different than slacker. Not as loud also in addition to sound quality difference.

My BT (iphone) streaming sounds better than Slacker, although i don't find Slacker that bad. I do notice that sometimes the volume on my phone is turned down and that impacts the BT sound quality in the Tesla.

Phone is an iPhone XS, quality is 160kbit/sec through spotify. Spotify sounds great from iphone over bluetooth to other sources (home stereo etc.) Volume is turned up on the phone.

Maybe I need a service center appointment.

I thought bluetooth was limited to 64kbps via bluetooth on the 3's for some strange reason?

Maybe that's not correct, perhaps it's an issue/incompatibility with the phone/car's decoders?

Update for all of you also having this issue - I turned off "normalization" in spotify's settings and the problem appears to have gone away.

This is strange because it's ONLY a problem on the 3. S works fine with normalization on, and so do other BT connections, so it's some kind of model3 bug.
