What Size Does the Album Art Need to Be to Work on a 7 Car Audio System

Anthology art can be embedded into MP3 files fairly easily using ID3 tags. Yet, before yous start filling up all of your MP3 files with works of fine art, in that location are a few things that you should end to consider showtime.

While MP3 files were not originally intended to shop additional metadata within them, the release of the ID3 tag protocol in 1996 suddenly made this a possibility. However, it wasn't until version ii of the protocol became available that MP3 files could actually contain embedded album art.

Then, before you start cutting and pasting huge graphics and calculation them into your collection of MP3 tracks, what do you need to consider to avert potential disaster?

ID3 Tags and MP3 Files

A standard MP3 file only contains audio information, with no additional data about the artist or type of audio contained within it. To include such extra information in an MP3 track, tag data is usually added to the outset or stop of the audio file in ID3 format.

ID3 tags allow yous to store additional information within your MP3 files such equally the track title, artist name and even album art. If yous're not familiar with ID3 tags, you may discover my previous commodity on What are ID3 tags in MP3 files? helpful.

Image Types

While the ID3v2 tag standard allows whatever type of image to be embedded in an MP3 file, it does advise that either PNG or JPEG formats should be used when interoperability with playback devices is required. Practically speaking JPEG images take been adopted every bit the de facto standard in this respect.

The ID3 standard is very flexible with regards to the blazon and number of images that tin exist embedded in a MP3 single file. The full list of different images that can be embedded are:

• $00 – Other
• $01 – 32×32 pixels 'file icon' (PNG only)
• $02 – Other file icon
• $03 – Cover (front)
• $04 – Cover (dorsum)
• $05 – Leaflet folio
• $06 – Media (due east.g. characterization side of CD)
• $07 – Atomic number 82 artist/lead performer/soloist
• $08 – Artist/performer
• $09 – Usher
• $0A – Band/Orchestra
• $0B – Composer
• $0C – Lyricist/text writer
• $0D – Recording Location
• $0E – During recording
• $0F – During operation
• $10 – Movie/video screen capture
• $11 – A vivid coloured fish
• $12 – Analogy
• $13 – Band/artist logotype
• $xiv – Publisher/Studio logotype

Quite an exhaustive list, and while a single MP3 file could embed all of the in a higher place images, in practice only i epitome is e'er usually embedded.

File Sizes

Unfortunately, any additional data that you add to an MP3 file will increase its file size and this is of particular importance when adding images due to their potential size, fifty-fifty with compressed images such as JPEGs.

Yet, this does demand to be taken in context. For example, calculation an 80kB JPEG image to a single 8MB podcast won't have a significant issue; it's only a 1% increase in file size.

If on the other manus you add an 80kB anthology epitome to every unmarried rails in your MP3 drove, let's say of one,000 songs, then you'll need any additional 80MB of storage, which could otherwise hold a farther 20 songs or so (some other 2 albums).

Current Media Player Back up

Windows Media Player embeds album artwork every bit 200 x 200 pixel images, although volition display larger images if they are embedded in the playing file equally a larger size. iTunes currently displays anthology art as 200 ten 200 pixel images. The picture to the right is sized at 200 x 200 pixels by way of case and is 35kB in file size.

The resolution of the iPod nano and iPod classic screens is 320 x 240 pixels. The iPod touch screen is 480 x 320 pixels, more than than sufficient to display images of 200 x 200 pixels.

The Current Standard

The majority of podcasts that include images embedded within them adopt an epitome size of 300 x 300 pixels.

The picture show to the right is sized at 300 x 300 pixels and is 62kB in file size by way of example.

JPEG images of these dimensions will vary in file size (dependant on the compression ratio used and epitome complication) from effectually 10kB to 80kB or so. A 300 ten 300 pixel prototype is actually over twice the size of a 200 10 200 image, and will consequently atomic number 82 to approximately double file sizes.

Adding Your Ain Pictures

So if you're producing your own podcast and want to heighten it with your ain logo, or just desire to embellish some of the tracks that you lot already have in your MP3 collection with album art, what'due south the best way forrard?

It'due south probably best to standardise on JPEG images to ensure that your artwork can be seen on the majority of possible playback devices.

Image sizes are probably best gear up at 300 10 300 pixels to display in reasonable quality on most playback systems. However, if you're concerned well-nigh the space taken up by these images, 200 x 200 pixel images may be the ameliorate option for you lot, reducing the image file size to near half that of a 300 10 300 pixel image. The BBC (a useful technical yardstick I've always constitute) embed 300 x 300 images in their podcasts.

If your current software doesn't let you to embed or add images to your MP3 files directly, and so standalone tag editing software should offer you this functionality. Some useful examples of such are:

• EasyTAG
• Filerename.co.great britain
• Jaikoz
• Mp3tag
• TagTuner
• Tag&Rename
