Restoring lost frequencies to hear more of your music Listening to your favourite tracks on the move can really lift your spirits – especially when you spend long hours in the car. But not when they don’t sound as good as they should…

The engineering story

Inspiration

Compressing audio from CD to MP3 can cause a loss in sound quality, as frequencies are removed from the original source to make the file smaller.

And it’s the high frequencies that suffer the most.

Creation

Other companies try to restore MP3 files but can only manage it up to 128kbps. Our engineers wanted to go one step further. They wanted to restore lost frequencies for all popular compression rates, not just one, using a single built-in technology.

So they tested music playback at every conceivable compression rate to ensure their idea would work, before injecting it into our Xplod car stereo range.

Digital Music+ Advanced was born...

Demonstration

Designed to revitalise MP3 tracks, DM+ Advanced restores high frequencies lost during the compression process. You don't need to worry about how much your music has been compressed either, as DM+ Advanced is automatically optimised for any bit rate.

So as well as incredible Sony sound quality as standard, the Xplod in-car range dramatically enhances playback for all your MP3 music – without you even telling it to...
