20080215330 | Audio Signal Modification - A method of modifying an audio signal comprises the steps of analyzing the input audio signal (x) so as to produce a set of filter parameters (p) and a residual signal (r), modifying the set of filter parameters (p) so as to produce a modified set of filter parameters (p′), and synthesizing an output audio signal (y) using the modified set of filter parameters (p′) and the residual signal (r). The set of filter parameters (p) comprises poles (λ | 09-04-2008 |
20080275709 | Audio Encoding and Decoding - A method of encoding a digital audio signal, wherein for each time segment the signal is spectrally flattened to obtain a spectrally flattened signal (r) and possibly spectral flattening parameters (LPP). The spectrally flattened signal is modelled by an excitation signal comprising a first partial excitation signal (p | 11-06-2008 |
20080312915 | Audio Encoding - A hybrid sinusoidal/pulse excitation encoder has been recently proposed for constructing a scalable audio encoder The base layer consisting of data supplied by the sinusoidal encoder retains the main features of the input signal achieving medium to high quality audio at a very low bit rate. Quality can be further enhanced by adding excitation signal layers associated with a decreasing decimation that increasingly model more subtle aspects of the original signal. The invention provides a method of mixing the different excitation signal layers so that the full concept of scalability is realised without compromising the quality of the encoded signals. The mixing is controlled via a quality parameter that weights the significance of previous layers when constructing a new higher layer. | 12-18-2008 |

20140276099 | DEVICE AND METHOD FOR DETERMINING VITAL SIGNS OF A SUBJECT - A device for determining a vital sign of a subject comprises an interface that receives a data stream derived from detected electromagnetic radiation reflected from a region of interest including a skin area of the subject, said data stream comprising a data signal per skin pixel area of one or more skin pixels for a plurality of skin pixel areas of said region of interest, a data signal representing the detected electromagnetic radiation reflected from the respective skin pixel area over time. An analyzer analyzes spatial and/or temporal properties of the skin area. A processor determines a vital sign information signal of the subject based on the data signals of skin pixel areas within the skin area, and a post-processor determines the desired vital sign from said vital sign information signal, wherein said determined spatial and/or temporal properties are used by the processor for determining the vital sign information signal and/or by the post-processor for determining the desired vital sign. | 09-18-2014 |
