Title: The Innovative Contributions of Sebastian Streich
Introduction
Sebastian Streich is a notable inventor based in Delft, Netherlands. He has made significant contributions to the field of audio analysis and sound signal processing. With a total of 7 patents to his name, Streich's work has advanced the technology used in audio systems.
Latest Patents
One of his latest patents is an audio analysis apparatus. This apparatus includes a component acquirer that obtains a component matrix composed of an array of component values. The columns of this matrix correspond to the sequence of unit periods of an audio signal, while the rows correspond to a series of unit bands arranged in a frequency-axis direction. A difference generator within the apparatus creates multiple shift matrices by shifting the columns of the component matrix in the time-axis direction. It also generates difference matrices that represent the differences between the component values of the shift matrix and the component matrix. Additionally, a feature amount extractor generates a tonal feature amount that includes a series of feature values corresponding to the difference matrices.
Another significant patent is related to a sound signal processing apparatus and method. In this invention, character values of a sound signal are extracted for each unit portion. The degrees of similarity between these character values are calculated and arranged in a matrix configuration. This matrix compares the sound signal with a delayed version of itself, identifying repetition probabilities and peaks in the distribution of these probabilities. This process aids in identifying loop regions within the sound signal.
