AT&T and Digigram Sign License Agreement for Advanced Audio Technologies.Business Editors/Hi-Tech Writers MONTBONNOT, France--(BUSINESS WIRE)--Feb. 15, 2001 Digigram to Create Multichannel Using two or more paths for transmission or processing. It can refer to a variety of architectures including (1) multiple I/O channels between the CPU and peripheral devices, (2) multiple wires in a cable, (3) multiple "logical" channels within a single wire or fiber or (4) multiple Audio Products Using AT&T Labs Implementation of MPEG-2 Advanced Audio Coding (audio) Advanced Audio Coding - (AAC) A successor to MP3, allowing lower bit rates and more stable quality. See MPEG-2 AAC Low Profile and MPEG-4 AAC Main Profile. (AAC (Advanced Audio Coding) An audio compression technology that is part of the MPEG-2 and MPEG-4 standards. AAC, especially MPEG-4 AAC, provides greater compression and better sound quality than MP3, which also came out of the MPEG standard. ) Digigram, an innovator in networking solutions for digital audio and remote management, announced today that it has signed an agreement with AT&T to license AT&T Labs implementation of the MPEG-2 AAC software. Digigram plans to deploy AT&T Labs' software in its newly designed multichannel professional audio codecs. "The new products we develop from this agreement with AT&T Labs will fuel the creation and deployment of next-generation audio content for broadband markets," said Digigram president Philippe Girard-Buttoz. The license allows Digigram to create products incorporating AT&T Labs' highly-optimized AAC software. AAC is the latest technology co-developed by experts in the art and science of audio compression Encoding digital audio data to take up less storage space and transmission bandwidth. Audio compression typically uses lossy methods, which eliminate bits that are not restored at the other end. ADPCM and MP3 are examples of audio compression methods. See audio codec and data compression. , and standardized as part of the MPEG-2 specification. Seen as the successor to MPEG-1 Layer 3 (MP3) audio compression technology, AAC provides higher quality audio reproduction, yet it requires approximately 30% less data. Digigram will integrate AT&T Labs' AAC software into its network audio platforms for the professional encoding and management of audio. "Our licensing agreement with Digigram is an example of how we strategically pair solutions and technology," said Rich Cox, Speech and Image Processing image processing Set of computational techniques for analyzing, enhancing, compressing, and reconstructing images. Its main components are importing, in which an image is captured through scanning or digital photography; analysis and manipulation of the image, accomplished Services vice president, AT&T Labs. "We are confident that Digigram will help raise the standard of next-generation audio services with our AAC technology." Digigram will offer hardware and software multichannel encoding tools that feature AAC as earlier as the third quarter of 2001.
