MULTICHANNEL AUDIO INTERCEPTION AND REDIRECTION FOR MULTIMEDIA DEVICES
A system and method for multichannel audio interception and redirection for ANDROID™-based devices, comprising an audio redirector software module that detects available hardware capabilities, configures and reports audio channel capabilities based on the detected hardware capabilities, de-multiplexes received audio, and provides de-multiplexed audio channels to both a sound processing framework and external audio rendering hardware.
1 . A system for multichannel audio interception and redirection for multimedia devices, comprising:
an audio redirector comprising at least a plurality of programming instructions stored in a memory and operating on a processor of a network-connected computing device and configured to:
connect to a sound processing framework of an operating system operating on the computing device;
receive an audio stream from an audio source;
process at least a portion of the audio stream, the processing comprising at least a de-multiplexing operation that produces a plurality of audio channels;
send at least a portion of the de-multiplexed audio channels to the sound processing framework for playback on the computing device; and
send at least a portion of the de-multiplexed audio channels to a plurality of external audio playback devices via a network for playback on the plurality of external audio playback devices.
2 . The system of claim 1 , wherein the sound processing framework is the Advanced Linux Sound Architecture.
3 . The system of claim 2 , wherein the operating system is an ANDROID™ operating system.
4 . A method for multichannel audio interception and redirection for mobile devices, comprising the steps of:
detecting, using an audio redirector comprising at least a plurality of programming instructions stored in a memory and operating on a processor of a network-connected computing device, audio hardware capabilities of the computing device;
configuring audio channels based at least in part on the detected hardware capabilities;
reporting audio channels to an audio source;
receiving an audio stream from the audio source;
de-multiplexing the received audio stream to produce a plurality of independent audio channels;
providing at least a portion of the audio channels to a sound processing framework operating on the computing device for playback on the computing device; and
providing at least a portion of the audio channels to a plurality of external audio playback devices based at least in part on the detected hardware capabilities for playback on the plurality of external audio playback devices.
