![]() ![]() It would be great if we could get Ldac or atx HD in the bimmer. In my f10 with the Harmon Kardon system I can only use SBC or AAC though and in my ears, SBC sounds better. Android uses a more common SBC codec and has options for several other higher quality codecs like aptx or LDAC. I'd venture to guess that's what you are hearing. (one would think within the car this wouldn't fluctuate much, and be a solid signal, but who knows). ![]() It's a variable bititrate codec, based on signal quality. Apple defaults to the AAC Bluetooth codec. Ive even tried it at Very High which is 320 - and same resultĪm I missing something? A setting or update I need to make to my car or phone? The player is Spotify downloaded playlists set at the HIGH setting which the app states that it should be downloaded at 160 bit/s The source is a iPhone 8 Plus on latest iOS I have a question - I'm not really looking for louder - but better audio qualityĬurrently on my B&O system - when using BT I can hear the bit rate or quality going up and down These are also reported to knock out frequencies at both ends of the mlai I accept that there are going to be better DAC's available than within the BMW audio systems but I think you're kidding yourself if you think you're going to achieve better sound quality via that route.Īlso, I seem to recall the AUX in has both capacitors and resistors inline to reduce static and voltages which could damage the idrive. When played back to back with either of the other two inputs it most certainly could mean 'aux half way is just as loud' ![]() The AUX in is going to be affected greatly by whatever is plugged into it, the volume it is set to and the EQ settings of the device attached are all going to have an effect. The OP considers his Aux in sound quality to be better than his USB or bluetooth connection as to him it is 'louder'. Playing the music via AUX bypassed all those DAC in the BMW audio system, and thus bypassing any audio inefficiencies introduced by the onboard digital system. With music stored on AK120, and played via AUX, you will get way better resolution of the sound, provided that you have really high quality music sources (192k/24bit) to take advantage of that. Most of these compressed music will have to go thru decoding, and internal DAC and this is where it matters a lot! The quality of the DAC of the CIC/NBT units are just not comparable to real HQ DAC units like Astell and Kren AK100 or AK120s. If you import, the music most likely will just get copied onto the hard-drive. If you rip CD into the hard-drive, it will get compressed, most likely to MP3. However, that's only one part of the equation. NBT systems are limited at FLAC 96K/24bit which are HiDef(have not tried 192K/24bit yet.) Both systems MAYBE able to play DVD-Audio, which are higher quality than CD. Put it simply, for CIC systems, the best quality is limited at CD quality, or WMA Lossless at 44.1K/16bit. And from our local F10 gatherings, we have the same conclusion that AUX sounded best, provided that you have a great audio source. Sound quality depends on a lot of different things, and the source actually plays the most important factor. ![]()
