Al menos, la estación base (3) y opcionalmente algunos dispositivos secundarios (2), cuentan además con un dispositivo de grabación de sonido (20), un algoritmo que estima el número de vehículos por unidad de tiempo que pasan por la vía donde está ubicada y medios de visualización que muestran a distancia los niveles de ruido consistentes en una pantalla (21) de grandes dimensiones que, en tiempo real, muestra un código de colores.
Abstract:
A processing system includes methods to promote sleep. The system may include a monitor such as a non-contact motion sensor from which sleep information may be determined. User sleep information, such as sleep stages, hypnograms, sleep scores, mind recharge scores and body scores, may be recorded, evaluated and/or displayed for a user. The system may further monitor ambient and/or environmental conditions corresponding to sleep sessions. Sleep advice may be generated based on the sleep information, user queries and/or environmental conditions from one or more sleep sessions. Communicated sleep advice may include content to promote good sleep habits and/or detect risky sleep conditions. In some versions of the system, any one or more of a bedside unit 3000 sensor module, a smart processing device, such as a smart phone or smart device 3002, and network servers may be implemented to perform the methodologies of the system.
Abstract:
Methods and devices for flexible and adaptable outputting of audio files in text or audio format based on certain parameters are described.Before delivering an acquired audio file to a user, the methods and devices described herein detect a current value of a pre-specified parameter,such as an environmental noise parameter,a mute setting parameter,a ring tone setting parameter,an audio/video playback parameter,or a setting parameter of an application acquiring the audio file,and compare the current value of the pre-specified parameter with a preset condition for the same parameter.The methods and devices described herein with output the audio file or a text file created from the audio file depending on the result of the comparison.
Abstract:
The invention relates to a measurement method for measuring the loudness range of an audio signal. In particular, said loudness range is measured in real time. Measuring apparatuses for implementing said method are also proposed (Figs. 1, 2). Such measuring apparatuses (920, 1020) are further used in control apparatuses for controlling the loudness range of the audio signal in real time. (Figs. 9, 10)
Abstract:
An RMS detector using first-order regressor with a variable smoothing factor is modified to penalize samples from center of data in order to obtain RMS values. Samples which vary greatly from the background noise levels are dampened in the RMS calculation. When background noise changes, the system will track the changes in background noise and include the changes in the calculation of the corrected RMS value. A minimum tracker tracks the minimum rms value, which is used to compute a normalized distance value, to normalize the smoothing factor. A corrected or revised RMS value is determined as the function of the previous RMS value multiplied by one minus the smoothing factor plus the smoothing factor times the minimum rms value to output the corrected RMS for the present invention. The rms value is used to generate a reset signal for the minimum tracker and is used to avoid deadlock in the tracker, for example, when the background signal increases/decreases over time.
Abstract:
Embodiments are directed to a method and system for receiving, in a bitstream, metadata associated with the audio data, and analyzing the metadata to determine whether a loudness parameter for a first group of audio playback devices are available in the bitstream. Responsive to determining that the parameters are present for the first group, the system uses the parameters and audio data to render audio. Responsive to determining that the loudness parameters are not present for the first group, the system analyzes one or more characteristics of the first group, and determines the parameter based on the one or more characteristics.
Abstract:
Implementations described herein may include activating an audio source associated with a graphical user interface, the audio source having an initial location associated with the graphical user interface. Some implementations may further include sensing a displacement of the audio source with respect to the initial location and determining that the displacement of the audio source exceeds a predetermined threshold. In some implementations, in response to determining that the displacement of the audio source exceeds a predetermined threshold, the process may include adjusting a level of audio associated with the audio source.
