Mobile music services took another step towards standards-driven service delivery today, with news that the standard-setting body has approved a form of AAC for music delivery on 3G handsets.

A release says: "Following the 3GPP announcement of MPEG-4 High-Efficiency AAC as the codec of choice for delivery of audio content to future 3G devices, Ahead Software have announced VHDL core, capable of decoding 3GPP audio, (HE-AAC v2 — with parametric stereo extensions) as well as legacy Low Complexity AAC and High Efficiency AAC audio, already used in online music delivery over the internet."

HE-AAC v2 offers high audio quality at bit rates as low as 24kbps. This version has been developed by Ahead Software. The advantage of this implementation is that it includes an integrated digital equalizer inside the AAC core, which reduces power consumption and means extra electronic devices are not required in the handset.

This latter follows common practice in the mobile handset industry, where manufacturers tend to favour components capable of doing multiple tasks, to make units smaller.

"With a single chip solution, it is now possible to decode all the latest industry standards in multimedia coding, while at the same time, beating the DSP competition in power consumption and price - a feature highly recommended for mobile products," the release said.

Apple's QuickTime chief, Frank Casanova, will deliver a keynote speech at the Cellular Telephone and Internet Association (CTIA's) Wireless IT and Entertainment 2004 event between October 25-27 in San Francisco.

He'll share the stage with Qualcomm Wireless and Internet Group president, Dr. Paul Jacobs and Vodafone Group Services executive head of content development, Graeme Ferguson.
