Audi MMI album art

It's always interesting to hear of new ways and situations bliss is used in. I recently received an email from a bliss customer who used bliss to fix album artwork for his car.

In his own words...

I bought Bliss so that I could properly embed album art into my iTunes library so that it would show the art on the MMI display in my new Audi, which contains an SD card copy of that library. I’m pleased to say that it did a very nice job and I’m now fully arted up in the car.

The Audi MMI is an advanced in-car entertainment and control system, with a nice large full colour display ideal for displaying album artwork while your music is playing. Naturally, having the album artwork also makes it easier to browse and enqueue your music.

However, like a lot of music playing hardware/software, there are limitations on the artwork that can be displayed.

Audi MMI album art rules

My correspondent went on to explain the constraints placed on album artwork in the Audi MMI:

  • Artwork must be no larger than 500x500 pixels in resolution.
  • Artwork must be no larger than 256KB in storage size.
  • Only one piece of embedded artwork is permitted in each file.

(Note: the resolution limit of 500x500 applies to the standard 5" display. Larger displays of 7" are available; for these the maximum resolution is 800x800).

Where artwork broke these rules, it simply wasn't displayed. These constraints are actually quite limiting; I would normally recommend resolutions higher than 500x500 for example. This makes the case for managing multiple music libraries.

One positive point is that the MMI supports embedded artwork, so that makes transferring music a bit easier.

These constraints make a rules oriented piece of software like bliss ideal to ensure compliance against these requirements. Using bliss, we can set constraints on our artwork such that it obeys these rules and displays in the car's MMI.

How to configure bliss to fix Audi MMI cover artwork

bliss works on Windows, Mac and Linux platforms. Before following the instructions below, download and install bliss, following the installation instructions.

Once you start bliss and visit the Albums page, click settings:

Settings: selecting the music folder and enabling the cover art rule

Enter the location of your Audi's music library (this may be direct to the SD card you insert into your car) and click Add and change cover art. You get the cover art settings:

Click 'more' to get more advanced control

Click more to reveal the sizing rules:

Enter sizing rules

We can now set the Audi MMI album art rules as laid out above. Change Maximum size to be Large (500x500), Maximum size (KB) to be 256KB and finally check Enforce singular embedded art.

You can enable Shrink art automatically if you want bliss to reduce the resolution of artwork without your say-so. Otherwise, size reductions will be offered in a one-click fix.

Now click Apply rules and bliss will begin assessing and fixing your artwork!

Once an album has been assessed it will be marked as Compliant (against your rules) or Non-compliant. If it's the latter, a one click fix will offer to reduce the size of your artwork, whether in terms of resolution or data size, or strip extraneous embedded artwork.

I hope that helps with your Audi MMI artwork woes.

Any more interesting uses of bliss? Let me know!
