本文提出UPV_RIR_DB,一个结构化的实测房间混响响应(RIR)数据库,包含明确的空间元数据和可追溯的采集参数。该数据集目前包含西班牙瓦伦西亚理工大学(UPV)三间房间的166组多通道RIR文件,每组包含多个声源-接收器对,每对覆盖25 cm²区域(典型个人声区大小)。根据麦克风模态对应的声源与接收通道数量,全库共含18,976个独立脉冲响应。采用分层组织架构,目录结构与元数据共同描述测量环境。每间房配备元数据文件,包含采集参数、硬件信息、声区与麦克风空间坐标及混响时间等声学指标。中心索引将每个RIR文件与其实验上下文关联,确保可追溯性,支持可复现分析。该数据库提供一致框架用于存储、检查与重用真实RIR数据,兼容MATLAB与JSON工作流。数据集已通过开放平台Zenodo公开获取。

原文摘要 · Abstract (English)

This paper presents UPV_RIR_DB, a structured database of measured room impulse responses (RIRs) designed to provide acoustic data with explicit spatial metadata and traceable acquisition parameters. The dataset currently contains 166 multichannel RIR files measured in three rooms of the Universitat Politècnica de València (UPV). Each multichannel RIR file contains impulse responses for multiple source-receiver pairs, with each pair covering a 25 cm2 area - the typical size of a personal sound zone. Considering the number of sources and receiver channels associated with each microphone modality, the database contains a total of 18,976 single impulse responses. A hierarchical organization is adopted in which directory structure and metadata jointly describe the measurement context. Each room includes a metadata file containing acquisition parameters, hardware description, spatial coordinates of zones and microphones, and acoustic indicators such as reverberation time. A central index links each RIR file with its experimental context, ensuring traceability and enabling reproducible analysis. The resulting database provides a consistent framework for storing, inspecting, and reusing real RIR measurements while preserving compatibility with both MATLAB- and JSON-based workflows. The UPV_RIR_DB dataset is publicly available through the open repository Zenodo.
