Nuernberg, Germany (January 29, 2007)–Coding Technologies announced an upgraded release of its MPEG-4 aacPlus Audio Encoder engine. The company’s aacPlus audio codec is the audio compression format of choice across a variety of industry standards, systems and applications, including, MPEG, DVB, DMB, 3GPP.
According to Coding Technologies, the enhanced encoder achieves significant improvements in audio fidelity and listening experience without any associated increase in bandwidth consumption. This allows content service providers to “dial-down” transmission bandwidth usage without affecting or sacrificing established audio quality. These increased audio quality gains are realized in every application level including: digital broadcasting, Over-the-Air (OTA) music downloads, high quality music ring tones and Internet Streaming.
The new encoder enhancements also lead to significantly improved speech quality and multi-channel audio fidelity at even lower bit rates. For example, says the company, delivering 5.1 surround sound now only requires 128 kbps; previous versions required 160 kbps. aacPlus is capable of delivering CD quality stereo at 48 kbps. In comparison, CD quality for MP3 is typically rated at 128 kbps.
“Delivering the best audio experience in the most efficient manner possible is the name of the game,” said Roger Bolton, vice president of business development at TANDBERG Television where MPEG-4 aacPlus multi-channel audio is included in the video compression industry leader’s latest MPEG-4 AVC encoders for HDTV. “The new version of aacPlus delivers excellent quality and will provide the high levels of performance our customers require from audio to complement their high definition video output.”
The Coding Technologies aacPlus encoder solutions empower some of the world’s most cutting-edge wireless music and television services available, including AOL, KDDI, NTT DoCoMo, REAL, Sprint and XM Satellite Radio. In the mobile space, Coding Technologies estimates that the number of aacPlus enabled mobile phones sold worldwide by the end of 2006 approached 200 million units.
