Doubly compatible lossless audio bandwidth extension
An encoder for digital audio signals at a higher sample rate creates a stream for consumer distribution at a lower sampling rate, with compatibility for standard pcm players without a decoder. In conjunction with a suitable decoder, two enhanced playback options are supported, the first option allowing full lossless reconstruction of a noise-shaped higher sampling rate signal, the second option allowing lossy bandwidth extension even if an intervening transmission chain has truncated the least-significant-bits of the encoder's output signal..

Method and device for improving the rendering of multi-channel audio signals
Conventional audio compression technologies perform a standardized signal transformation, independent of the type of the content. Multi-channel signals are decomposed into their signal components, subsequently quantized and encoded.
Audio apparatus and controlling method thereof
An audio apparatus and method are provided. The method includes receiving, by a controller, first audio data and second audio data and processing the first audio data and the second audio data to generate first audio signals and second audio signals.

Interactive waste receptacle
An interactive waste receptacle combines a waste receptacle, a display device, a sensor, a camera, a speaker, and a variety of interactive media to receive and process waste, and perform an assortment of interactive functions in a public venue. The interactive waste receptacle detects events from a user, and responds to the events with interactive functions, including; receiving, compacting, and processing a waste; detecting proximal images, sounds, and smells; and displaying advertisements, text, graphics, animation, video, audio, and games.
Encoding and decoding of audio signals
An encoder (1201) for encoding a plurality of audio signals comprises a selector (1303) which selects a subset of time-frequency tiles to be downmixed and a subset of tiles to be non-downmix. A downmix indication is generated which indicates whether tiles are encoded as downmixed encoded tiles or as non-downmix tiles.
