摘要： One or a combination of two or more specific loudness model functions selected from a group of two or more of such functions are employed in calculating the perceptual loudness of an audio signal. The function or functions may be selected, for example, by a measure of the degree to which the audio signal is narrowband or wideband. Alternatively or with such a selection from a group of functions, a gain value G [t] is calculated, which gain, when applied to the audio signal, results in a perceived loudness substantially the same as a reference loudness. The gain calculating employs an iterative processing loop that includes the perceptual loudness calculation.

摘要： A motion picture soundtrack reproduction system has a center front soundtrack channel and a plurality of other soundtrack channels. A volume control adjusts the gain of all the channels. The volume control has a range of settings from a minimum to a maximum, the gain of the center front channel having substantially a first relationship to the volume control settings and the gain of the other channels having substantially a second relationship to the volume control settings, the relationships being such that for a range of volume control settings less than a first setting the gain of the center front channel remains substantially constant while the gain of the other channels decreases as the setting decreases or decreases more gradually than the gain of the other channels as the setting decreases.

摘要： An audio signal is conveyed more efficiently by transmitting or recording a baseband of the signal with an estimated spectral envelope and a noise-blending parameter derived from a measure of the signal’s noise-like quality. The signal is reconstructed by translating spectral components of the baseband signal to frequencies outside the baseband, adjusting phase of the regenerated components to maintain phase coherency, adjusting spectral shape according to the estimated spectral envelope, and adding noise according to the noise-blending parameter. Preferably, the transmitted or recorded signal also includes an estimated temporal envelope that is used to adjust the temporal shape of the reconstructed signal.

摘要： Multi-layered motion or still video compression includes, in an encoder or encoding function aspect of the invention, separating the video signal into low-frequency and high-frequency components, processing the low-frequency components of the video signal to generate synthetic high-frequency components, the low-frequency components or a data reduced version of the low-frequency components comprising a main or base layer, and generating the difference between the synthetic high-frequency components and the actual high-frequency components, the difference comprising an error or enhancement layer signal. A decoder or decoding function aspect of the invention processes the main layer to generate synthetic high-frequency components and combines the synthetic high-frequency components, main layer and enhancement layer to provide a decoded output signal similar to the video signal applied to the encoder.

摘要： In one aspect, the invention divides an audio signal into auditory events, each of which tends to be perceived as separate and distinct, by calculating the spectral content of successive time blocks of the audio signal (5-1), calculating the difference in spectral content between successive time blocks of the audio signal (5-2), and identifying an auditory event boundary as the boundary between successive time blocks when the difference in the spectral content between such successive time blocks exceeds a threshold (5-3). In another aspect, the invention generates a reduced-information representation of an audio signal by dividing an audio signal into auditory events, each of which tends to be perceived as separate and distinct, and formatting and storing information relating to the auditory events (5-4). Optionally, the invention may also assign a characteristic to one or more of the auditory events (5-5).

摘要： Using an apparatus like a cellular telephone, an operator is able to create a message by singing into the apparatus or by pressing buttons on the apparatus as he listens to background music presented by the apparatus. By pressing buttons, the operator is able to generate sounds as if he was playing a musical instrument. A remote server stores a representation of the operator vocal or tactile input, and sends a message to one or more recipients that renders the operator input and background music in a manner that substantially preserves the temporal relationship originally observed by the operator.
