Fraunhofer to Debut New MPEG Audio Codec for Android Mobile Phones


Fraunhofer IIS, an applied research organization, has announced that at the 2010 World Mobile Congress it will be unveiling a new set of MPEG audio codecs: MPEG-4 HE-AAC v2 and MPEG Surround for Android (News - Alert) mobile phones.

 
Android is a mobile operating system that uses a modified version of the Linux kernel. It allows developers to write managed code in the Java language, controlling the device via Google (News - Alert)-developed Java libraries.
 
The Android platform offers built-in encoding/decoding for a variety of common media types, so that developers can easily integrate audio, video and images into their applications.
 
Fraunhofer offers a wide range of Android operating system compatible codec including MPEG-4 HE-AAC v2 standard which is stated to be the choice for any mobile multimedia application including digital television and radio broadcasting as well as Internet radio streaming over 3G or Wi-Fi.
 
Fraunhofer has stated that its focus now is on newer audio technologies and their MPEG audio software portfolio for Android is complemented by additional innovative offerings, including MPEG AAC-LC, HD-AAC and AAC-ELD codec. All software libraries are specifically optimized for low resource consumption on Android-based devices.
 
Fraunhofer has also planned to introduce MPEG Surround, a new standard codec which brings multi-channel audio to mobile devices. MPEG Surround works on existing audio codec such as HE-AAC and due to this availability content providers can target mobile devices to deliver highest surround audio quality at stereo bit-rates to handsets equipped with conventional headphones.
 
This surround sound will improve music and video streaming as well as Mobile-TV services that too without an increase in audio bit rate. This feature is designed with backward compatibility so that legacy devices play the streams in excellent stereo quality
 
Accessing the platform's media capabilities is fairly straightforward in Android as it lets users play audio and video from several types of data sources. Android supports audio format MP3 M4A AMR, video format MP4 3GP.
