D4 2014 - Supported audio formats for USB drives

Hi all,

I have a LR Discovery 4 2014 HSE (with Meridian sound, I think). It has an USB port in the upper glove box where I can plug an USB drive to play music off it. The user manual states that it supports MP3, AAC and WMA audio formats.

I noticed that some MP3 songs from my collection don't play - the audio unit just skips them stating "file format error" (or something similar). I've spent an entire evening running in/from the car and trying different transcoding settings - like different constant/variable bitrate, frequency, etc, but could not find an exact format that would play _all_ the songs - some of they are playing, others - are not. I've got the same results with AAC.

Next, I tried WMA - and bingo! all songs were playing... or so I thought - I noticed that the music in WMA format has a way worse sound quality, despite I tried the highest quality supported by the format.

Question(s): does anyone know what is the highest quality audio format supported (with exact settings) that can be played from USB drive? Are there any other options to get a good quality sound?

Maybe some audio player/phone connected via AUX and playing FLAC would sound better?

Thank you in advance!

from experience (2011 XS though) it's a black art. wma will play but seems to have a file size limit.

mp3 seems bit-rate sensitive.

sometimes, just adding a file it won't play renders the whole usb-stick unusable, other times it's just the file you add.

I added some files last week and it suddenly started playing stuff I'd forgotten was already on there as well as the new stuff.

Im still having the same problem but with films. No one so far has been able to confirm which format it is happy with. Some play, some dont, some play the opening titles then fail.
Im thinking trial and error like you but first will have to download the same film in many formats and cannot see that happening any time soon.

Good luck though Thumbs Up

It is indeed.

Looks like it is also picky about the filesystem - it orders the files by creation date instead of name.

not sure about that sorting.

on mine it's alphabetical BUT I don't let my PCs rename files to include track numbers. Depending on what you are using to play the files, the track numbers are used whether you see them or not, but i hate Windows adding them into the file names.

all is still ok on the PC but when the files are then in the car, the disco doesn't know the order to play them ... so concept albums go to Censored as files play in name order.

I run my x264 or Xvid films through DivX converter and they all play fine at a max size of 720 x 400 Thumbs Up

Worthwhile deleting any album art you may have on there. Mine been much better since I did. It is however a tad erratic still.

TL;DR: if some MP3 files don't play - try to re-encode them using another codec. "LAME v3.100" did the trick for me.

Finally I've got some time to experiment and found that the MP3 format can be encoded differently - different codecs can produce different results, even when using same settings.

Previously I was using a program called "Format Factory" - not sure exactly which MP3 codec it uses, but the results were not playable in the car. I then checked the used codecs (where available) and bitrate settings and found that the vast majority of MP3s encoded using the "LAME" codec will play fine.

I downloaded another app "Audacity" and re-exported all unplayable songs one-by-one using highest quality with variable bit rate and now all songs are playing fine. Looks like not all MP3s are equal and my D4's infotaiment system is picky about what codec is used.
