Mobile users can now greet incoming callers with high fidelity music and audio instead of the common tones in use today

Coding Technologies, a provider of audio compression for mobile, digital broadcasting and the Internet, and SK Telecom, a mobile service provider in Korea, have successfully incorporated Coding Technologies’ aacPlus audio codec into SK Telecom’s Premium Color Ring Back Tone service (PCRBT) launched on March 13. The new aacPlus audio codec greatly improves the audio quality compared to the former service. The launch of SK Telecom’s PCRBT service constitutes a commercial proof of concept and is expected to impact the adoption of similar services in other countries. The first phone models supporting the new service are already available from vendors such as Motorola and Pantech.

Color Ring Back Tones allow mobile phone users to personalize their mobile phone service by selecting songs that callers hear when calling the user’s phone. Color Ring Back Tones are a much sought-after life-style accessory in the huge Asian markets with more than 12 million active users in South Korea.
