  • APPLICATION BULLETIN AAC-ELD Based Audio Communication on Ios a Developer’S Guide V2.3 - 08.08.2012
    F R A U N H O F E R I N S T I T U T E F O R I N T E G R A T E D C I R C U I T S I I S APPLICATION BULLETIN AAC-ELD based Audio Communication on iOS A Developer’s Guide V2.3 - 08.08.2012 ABSTRACT This document is a developer’s guide for accessing the AAC-ELD codec included in iOS from third party audio communication applications. It shows how developers can create their own innovative applications and services using the same high quality codec as in FaceTime. Source code examples are used to illustrate the required processing steps and Application Programming Interface calls. The complete source code is available together with this paper and comprises a working demo application, which reads audio frames from the microphone and plays them back at low delay after encoding and subsequent decoding. The discussed iOS APIs include full-duplex audio Input/Output using the Remote I/O AudioUnit and AAC-ELD encoding/decoding using the AudioConverter API. The initialization of components and underlying concepts, such as the usage of callback functions and object properties are discussed. The scope of the example application is limited for simplicity and does not cover transmission over IP or other advanced features such as error concealment or jitter buffer management. The integration of all these components into a complete Voice over Internet Protocol application is a challenging task but can be simplified through the Fraunhofer Audio Communication Engine, which is described briefly at the end of the document.
