Platforms

A team specialized on the efficient implementation of multimedia technologies on various PC and DSP platforms as well as operating systems guarantees Fraunhofer IIS clients instant access to turnkey solutions.

Optimized DSP and Microcontroller Implementations

For real-time implementations of multimedia codecs and components on embedded processor cores and DSPs, Core Design Kits (CDKs) are available. They are optimized for devices with low resources in terms of memory and computational power, e.g. mobile players or smartphones.
In basic terms, Core Design Kit software is suitable for any 16- or 32-bit processor platform. Code can be licensed in source code form or as object code libraries for various compiler tool chains: 

  • ARM based processors
  • Cadence/Tensilica HiFi Audio DSP
  • Texas Instruments C6x, DaVinci, OMAP
  • Analog Devices Sharc
  • Others: please inquire.

 

Implementations of the following technologies are available:

Fraunhofer IIS audio encoder and decoder for Android and the Apple iOS SDK

Fraunhofer IIS supplies optimized audio encoder and decoder libraries for use with Android-based systems, the Apple iOS Software Development Kit (SDK) and other mobile platforms. This versatile family of technologies enables radio stations, service providers and media player developers to introduce or improve mobile services incorporating industry-leading audio quality for smart phones.
High quality audio codecs by Fraunhofer IIS allow for a new generation of mobile services such as Internet radio for Android and iOS devices by:

  • Boosting the audio quality of mobile multimedia applications
  • Minimizing bandwidth requirements (xHE-AAC offers maximum coding efficiency and achieves good stereo quality at 16 kbit/s)
  • Enhancing service stability
  • Enabling a more satisfying user experience and lowering the costs per stream
  • Software encoders and decoders will help stimulate the audio accessories market

Fraunhofer IIS supplies optimized encoder and decoder libraries for the following audio codecs:

The Android and iPhone decoders from Fraunhofer IIS are part of the CDK (Core Design Kit) software concept.

Facts about the Fraunhofer FDK2 AAC Codec Library for Android

“Fraunhofer's FDK AAC code provides a complete, high-quality audio solution to Android users. Fraunhofer does not only contribute codec code, but also the audio systems knowledge and profound experience as the primary AAC and MP3 inventor.” - Google Inc.

  1. Fraunhofer IIS has been working on audio coding for more than 25 years and remains the worldwide respected authority in low bitrate high quality audio coding. Since 2012, the Fraunhofer IIS software implementations of the open ISO MPEG audio codecs AAC, HE-AAC, HE-AACv2 and AAC-ELD have been part of Android and the Android Open Source Project with the FDK AAC Codec Library. In 2018, the new version FDK2 was launched, and brings several new technologies to Android OEMs, service providers and developers, including xHE-AAC, MPEG-D DRC dynamic range control and AAC-ELDv2. Android users benefit from the high audio quality of the Fraunhofer FDK.
  2. The Fraunhofer FDK2 AAC Codec Library for Android is a low resource implementation of AAC encoders and decoders available for Android on ARM and x86 processors and is available from the Android source code tree.
  3. Fraunhofer continues to offer the CDK commercial libraries (see above), available for all major processors and operating systems, including iOS and Android under its standard commercial license. The Fraunhofer CDK software is also available for other MPEG audio standards.
  4. AAC is an open MPEG standard and many companies and organizations participated in the technical development and standardization process. A patent licensing program is administered by Via Licensing Alliance. There are currently more than 10 billion licensed devices. Please contact VIA on https://www.via-la.com/ for information on whether your application is already covered by an existing license.
  5. xHE-AAC extends the usable stereo bitrate range of AAC: from as low as 12 kbit/s up to 500 kbit/s, enabling subscription video on demand (SVOD) and streaming music distributors to globally offer an improved, more reliable consumer experience over congested networks and particularly in regions where consumers still rely on 2G or 3G connections. In addition, MPEG-D DRC will provide mandatory loudness control for xHE-AAC to playback content at a consistent volume and offers new dynamic range control profiles for listening in noisy situations.
  6. AAC-ELD and AAC-ELDv2 provide up to CD-comparable audio quality for communications applications. They avoid many of the problems typically found in speech codecs used today for real-time communications applications such as audio and/or video chat and VoIP. These problems are caused by, for example, background noise, multiple talkers, children’s voices, ring-back tones, music on hold, and music in general. AAC-ELD and AAC-ELDv2 enable new Android communication apps and services to transform everyday communications into an emotional, state-of-the-art rich-media experience.
  7. HE-AACv2 and HE-AAC Multichannel for high quality 5.1 surround sound are used in TV, radio and streaming services worldwide.
  8. AAC-LC is the high-performance audio codec for excellent audio quality. First used by the Japanese digital broadcasting system ISDB and for music download and mobile music playback, today AAC is used in all state-of-the-art consumer electronics devices.
