AI Technical Summary

Benefits of technology

This patented technology allows for efficient identification of specific sounds within an input sound file without relying solely upon their characteristics such as pitchiness or loudness levels. It uses advanced algorithms like neural networks (ANNs) trained with data from previously recorded training samples to improve accuracy over time. Additionally, this system has been developed into software packages called LSTM models, allowing them to perform multiple types of operations quickly while still maintaining good performance across different environments. Overall, these technical improvements make better ways to process audio signals more efficiently and accurately than previous methods.

Problems solved by technology

The problem addressed by this patented method is that current methods are limited when applied beyond certain specific areas such as recognizing musical accompaniment only on sound recordings while also being able to recognize both background noises and near field/far-field voices without affecting their overall quality level.

Abstract

The invention provides an audio signal processing method and device, electronic equipment and a storage medium. A specific embodiment of the method comprises the steps of obtaining an audio feature of a target audio signal, wherein the audio feature comprises at least one audio feature unit; and inputting each audio feature unit into a pre-trained machine learning model to obtain a corresponding audio category tag, wherein the audio category tag includes at least one of a near-field voice tag, a far-field voice tag, a music tag and a noise tag. According to the embodiment of the invention, whether the audio signal is voice or not can be identified, and whether the audio signal is a near-field voice,a far-field voice or music specifically can be identified so that reliable category information is provided for subsequent audio processing, and the audio processing efficiency and effect are greatly improved.
