Hi-Fi sound quality in New Mercedes Benz CLC

The Newest Mercedes Benz CLC with better sound system. The Mercedes Benz unveiled his C-Class CLC car in 28^th January 2008. The car radio with integrated CD player (MP3-compatible) features an FM/ MW, SW and LW tuner with automatic station search, RDS function (with FM reception), direct frequency selection via the keypad in the centre console and a five-inch color display.
This infotainment system combines car radio, telephone exchange and Europe-wide DVD navigation system in a single unit. Navigation instructions – including a junction zoom function -- are indicated using arrows on a color display (five inch). The integrated DVD drive can be used for navigation or audio data. If the (optional) six-disc DVD changer is fitted, Audio 50 APS also comes as standard with the enhanced LINGUATRONIC voice-operated control system with whole-word recognition capability.

 

The multimedia system includes a Europe-wide navigation system with the associated data stored on a hard disc (40 gigabytes). This provides lightning-fast access to navigation data and enables route information to be processed even faster. The roadmap is shown on a high-resolution 6.5-inch color display. COMAND APS also includes a music library with capacity for four gigabytes of music. Here the driver can store around 1000 tracks in MP3 format from CD, DVD or memory card. The system automatically identifies the tracks and performers and shows the information on the color display. Above the color display the unit has a slot for SD memory cards that can also be used as music storage media. As an option, COMAND APS is available from Mercedes-Benz with a six-disc DVD changer and voice-operated control system.  

For the first time an iPod, USB stick or other external audio devices can be connected up to the infotainment system in the Mercedes CLC courtesy of a newly developed universal interface; this interface is available ex factory for all infotainment systems in the new Mercedes CLC. Customers then simply need to obtain a compatible cable that is available from the Mercedes accessories range. 

The voice-operated control system is part of the standard specification for the Mercedes CLC if Mercedes customers specify the Audio 50 APS with six-disc DVD changer, or the COMAND APS multimedia unit. LINGUATRONIC conveniently operates the telephone, audio and navigation system using its whole-word recognition capability. So the driver no longer has to painstakingly spell everything out but can simply say each particular word when entering a destination, selecting a radio station or calling up a name included in the phone book.

The sound output is digitized during the brief dialogue, converted into a frequency spectrum and finally analyzed. Within a matter of milliseconds the computer extracts various features from the voice input and identifies the phonemes – the distinct sound units that make up speech. The software instantly verifies each sound, combines the various phonemes, compares them against the contents of a stored phoneme dictionary and also calculates the acoustic probability of the word. Consequently, the system can recognize even minute differences in pronunciation; for instance, it can differentiate between the words "street" and "straight". The system includes the phonemes for six different languages.
