Method and device for controlling the perceived loudness and/or the perceived spectral balance of an audio signal

Abstract: The invention relates to the measurement and control of the perceived sound loudness and/or the perceived spectral balance of an audio signal. An audio signal is modified in response to calculations performed at least in part in the perceptual (psychoacoustic) loudness domain. The invention is useful, for example, in one or more of: loudness-compensating volume control, automatic gain control, dynamic range control (including, for example, limiters, compressors, expanders, etc.), dynamic equalization, and compensating for background noise interference in an audio playback environment. The invention includes not only methods but also corresponding computer programs and apparatus.

Method for generating a surround sound field, apparatus and computer program product thereof.

Abstract: Embodiments of the present invention relate to adaptive audio content generation. Specifically, a method for generating adaptive audio content is provided. The method comprises extracting at least one audio object from channel-based source audio content, and generating the adaptive audio content at least partially based on the at least one audio object. Corresponding system and computer program product are also disclosed.

Method for controlling acoustic echo cancellation and audio processing apparatus

Abstract: A method for controlling acoustic echo cancellation and an audio processing apparatus are described. In one embodiment, the audio processing apparatus includes an acoustic echo canceller for suppressing acoustic echo in a microphone signal, a jitter buffer for reducing delay jitter of a received signal, and a joint controller for controlling the acoustic echo canceller by referring to at least one future frame in the jitter buffer.

Method and System for Split Client-Server Reverberation Processing

Abstract: In some embodiments, a method applying reverberation to audio from at least one client of a set of clients which share a virtual environment, including by asserting position data and at least one input audio stream to a server, selecting (in the server) a reverberation filter for each input audio stream in response to the position data and generating wet audio by applying to the input audio an early reverberation part of the selected reverberation filter. Typically, a client applies a late reverberation filter to the wet audio using metadata from the server. In other embodiments, a server selects a reverberation filter for application to audio in response to position data, asserts the audio and metadata indicative of the filter, and a client applies the filter to the audio using the metadata. Other aspects are systems, servers, and client devices configured to perform any embodiment of the method.

Dynamic dns system for private networks

Abstract: A DNS component functions privately in relation to a group of client devices, each associated with a unique URL maintained with the DNS component that privately identifies the devices within the group. The URL identifies a hierarchy of private domains enforced within the group which, at least implicitly, represents private relationships therein between the devices. Network rules are applied over the group based on the private relationships or the private domains. The devices are securely authenticated within the group. A content sharing service component allows devices within the group to access information content associated with other group devices based, at least partially, on the devices' URLs. A private IP based internet allows group devices secure access to the group from external networks and free access to other devices within the group.
