AID: Open-Source Anechoic Interferer Dataset

A dataset of anechoic recordings of various sound sources encountered in domestic environments is provided, which is intended to be a resource of non-stationary, environmental noise signals that, when convolved with acoustic impulse responses, can be used to simulate complex acoustic scenes. The dataset consists of anechoic recordings of 43 different types of sound sources encountered in domestic environments, with the number of individual recordings per sound source varying between two and eleven. The sound sources, which are mostly household devices and utilities, include door keys, plastic bags, clothing, a drilling machine, an electric blender, glass jars and metal boxes but also a few human-made sounds, such as clapping, breathing, snapping or whistling. The recordings cover a wide range of timbres. Multiple sounds from every individual source were recorded by different ways of excitation, such as hitting and shaking, or switching on and off the electric devices. Three different microphones were used to record the various sound sources.本数据集收录了家庭环境中常见各类声源的消声录音（anechoic recording），旨在构建非平稳环境噪声信号资源库；将该数据集与声学冲激响应（acoustic impulse response）进行卷积运算后，可用于模拟复杂声学场景。 该数据集共包含43种家庭环境常见声源的消声录音，每个声源对应的独立录音条数介于2至11条之间。 本次收录的声源以家用设备与日常用品为主，涵盖门钥匙、塑料袋、衣物、钻孔机、电动搅拌机、玻璃罐及金属盒等，同时包含若干人工发声场景，如拍手、呼吸、打响指与吹口哨。 本次录音覆盖了丰富的音色范围，针对每个声源采用多种激发方式录制多组音频，包括敲击、摇晃，或是启停用电设备。 本次录音共使用三款不同型号的麦克风完成各类声源的采集工作。
