Google has its native development kit for Android 4.0 an opportunity for developers added to get direct access to raw audio streams. This can drm be applied to audio streams.
With the new tools, developers can in Android applications for Ice Cream Sandwich, among other own decoders apply that compressed audio files into the pcm-audio. Also can applications directly audio files to encrypt, for example, for drm purposes. Google used for the improved access to audio streams OpenMAX AL, an interface in the programming language C of the Khronos consortium.
The new tools include interesting for companies that will an application wish to release for the streaming of audio and there – not forced drm on want to apply. Also for Android applications that audio files manipulate are the new additions to the software toolkit useful.
The extensions to the native development kit of Android 4.0 are not dependent on a specific chipset. Some drm modules that are in Android 3.0 were introduced, are also not tied to specific hardware, but this modular drm-modules do not offer low level access to audio files. As a result, the manipulatiemogelijkheden and the robustness of the encryption is limited.
