资源简介：

This dataset contains the ground truth data used to evaluate the musical pitch, tempo and key estimation algorithms developed during the AudioCommons H2020 EU project and which are part of the Audio Commons Audio Extractor tool. It also includes ground truth information for the single-eventness audio descriptor also developed for the same tool. This ground truth data has been used to generate the following documents: Deliverable D4.4: Evaluation report on the first prototype tool for the automatic semantic description of music samples Deliverable D4.10: Evaluation report on the second prototype tool for the automatic semantic description of music samples Deliverable D4.12: Release of tool for the automatic semantic description of music samples All these documents are available in the materials section of the AudioCommons website. All ground truth data in this repository is provided in the form of CSV files. Each CSV file corresponds to one of the individual datasets used in one or more evaluation tasks of the aforementioned deliverables. This repository does not include the audio files of each individual dataset, but includes references to the audio files. The following paragraphs describe the structure of the CSV files and give some notes about how to obtain the audio files in case these would be needed. Structure of the CSV files All CSV files in this repository (with the sole exception of SINGLE EVENT - Ground Truth.csv) feature the following 5 columns: Audio reference: reference to the corresponding audio file. This will either be a string withe the filename, or the Freesound ID (for one dataset based on Freesound content). See below for details about how to obtain those files. Audio reference type: will be one of Filename or Freesound ID, and specifies how the previous column should be interpreted. Key annotation: tonality information as a string with the form "RootNote minor/major". Audio files with no ground truth annotation for tonality are left blank. Ground truth annotations are parsed from the original data source as described in the text of deliverables D4.4 and D4.10. Tempo annotation: tempo information as an integer representing beats per minute. Audio files with no ground truth annotation for tempo are left blank. Ground truth annotations are parsed from the original data source as described in the text of deliverables D4.4 and D4.10. Note that integer values are used here because we only have tempo annotations for music loops which typically only feature integer tempo values. Pitch annotation: pitch information as an integer representing the MIDI note number corresponding to annotated pitch's frequency. Audio files with no ground truth pitch for tempo are left blank. Ground truth annotations are parsed from the original data source as described in the text of deliverables D4.4 and D4.10. The remaining CSV file, SINGLE EVENT - Ground Truth.csv, has only the following 2 columns: Freesound ID: sound ID used in Freesound to identify the audio clip. Single Event: boolean indicating whether the corresponding sound is considered to be a single event or not. Single event annotations were collected by the authors of the deliverables as described in deliverable D4.10. How to get the audio data In this section we provide some notes about how to obtain the audio files corresponding to the ground truth annotations provided here. Note that due to licensing restrictions we are not allowed to re-distribute the audio data corresponding to most of these ground truth annotations. Apple Loops (APPL): This dataset includes some of the music loops included in Apple's music software such as Logic or GarageBand. Access to these loops requires owning a license for the software. Detailed instructions about how to set up this dataset are provided here. Carlos Vaquero Instruments Dataset (CVAQ): This dataset includes single instrument recordings carried out by Carlos Vaquero as part of this master thesis. Sounds are available as Freesound packs and can be downloaded at this page: https://freesound.org/people/Carlos_Vaquero/packs Freesound Loops 4k (FSL4): This dataset set includes a selection of music loops taken from Freesound. Detailed instructions about how to set up this dataset are provided here. Giant Steps Key Dataset (GSKY): This dataset includes a selection of previews from Beatport annotated by key. Audio and original annotations available here. Good-sounds Dataset (GSND): This dataset contains monophonic recordings of instrument samples. Full description, original annotations and audio are available here. University of IOWA Musical Instrument Samples (IOWA): This dataset was created by the Electronic Music Studios of the University of IOWA and contains recordings of instrument samples. The dataset is available upon request by visiting this website. Mixcraft Loops (MIXL): This dataset includes some of the music loops included in Acoustica's Mixcraft music software. Access to these loops requires owning a license for the software. Detailed instructions about how to set up this dataset are provided here. NSynth Dataset Test and Validation sets (NSYT and NSYV): NSynth is a large-scale and high-quality dataset of annotated musical notes built with synthesized sounds by Google's Magenta team. Full dataset description including original annotations and audio files is available here. Philarmonia Orchestra Sound Samples Dataset (PHIL): This includes thousands of free, downloadable sound samples specially recorded by Philharmonia Orchestra players. Audio files are freely downloadable from the philarmonia orchestra website. Freesound Single Events Dataset (SINGLE EVENT): This includes a selection of Freesound audio clips representing audio signals containing either a single audio event or multiple ones. Original audio files can be retrieved by downloading individual audio clips from Freesound using the ID identifier provided in the CSV file. A similar procedure to that described here could be followed.

本数据集包含用于评估音乐**音高（pitch）**、**速度（tempo）**与**调式（key）**估计算法的基准真值（ground truth）数据，这些算法由欧盟H2020项目AudioCommons开发，且属于Audio Commons音频提取器工具的组成部分。本数据集还包含为同一工具开发的**单事件性（single-eventness）**音频描述符的基准真值信息。这些基准真值数据曾用于生成以下交付文档： - **交付件D4.4**：音乐样本自动语义描述首个原型工具评估报告 - **交付件D4.10**：音乐样本自动语义描述第二个原型工具评估报告 - **交付件D4.12**：音乐样本自动语义描述工具发布所有上述文档均可在AudioCommons官网的资料板块获取。本仓库中的所有基准真值数据均以CSV文件形式提供。每个CSV文件对应上述交付件的一项或多项评估任务中使用的单个数据集。本仓库**不包含各单个数据集的音频文件**，但提供了音频文件的引用信息。下文将介绍CSV文件的结构，并在需要获取音频文件时提供相关说明。 ### CSV文件结构除*SINGLE EVENT - Ground Truth.csv*外，本仓库中的所有CSV文件均包含以下5列： 1. **音频引用（Audio reference）**：对应音频文件的引用信息，可为包含文件名（filename）的字符串，或（基于Freesound内容的数据集所用的）**Freesound ID**。获取这些文件的详细说明见下文。 2. **音频引用类型（Audio reference type）**：取值为"Filename"或"Freesound ID"，用于指定前一列内容的解析方式。 3. **调式标注（Key annotation）**：调性信息，格式为字符串"RootNote minor/major"，即“根音小调/大调”。无调式基准真值标注的音频文件对应的该字段留空。基准真值标注源自原始数据源，详见交付件D4.4与D4.10的文本说明。 4. **速度标注（Tempo annotation）**：速度信息，以整数形式表示每分钟节拍数（BPM）。无速度基准真值标注的音频文件对应的该字段留空。基准真值标注源自原始数据源，详见交付件D4.4与D4.10的文本说明。需注意此处使用整数取值，因为仅针对音乐循环（music loops）提供了速度标注，而这类循环的速度通常为整数。 5. **音高标注（Pitch annotation）**：音高信息，以整数形式表示对应标注音高频率的MIDI音符编号。无音高基准真值标注的音频文件对应的该字段留空。基准真值标注源自原始数据源，详见交付件D4.4与D4.10的文本说明。剩余的CSV文件*SINGLE EVENT - Ground Truth.csv*仅包含以下2列： 1. **Freesound ID**：Freesound平台用于标识音频片段的声音编号。 2. **单事件标注（Single Event: ）**：布尔值，用于指示对应声音是否被视为单事件音频。单事件标注由交付件的作者按照交付件D4.10中描述的方法收集。 ### 如何获取音频数据本节提供获取与本数据集基准真值标注对应的音频文件的相关说明。需注意，由于许可限制，我们无法重新分发大多数基准真值标注对应的音频数据。 - **Apple Loops (APPL)**：本数据集包含Apple音乐软件（如Logic或GarageBand）中的部分音乐循环。获取这些循环需拥有对应软件的授权。本数据集的详细配置说明见此处。 - **Carlos Vaquero Instruments Dataset (CVAQ)**：本数据集包含Carlos Vaquero在其硕士论文中录制的单乐器录音。这些声音以Freesound打包形式提供，可在https://freesound.org/people/Carlos_Vaquero/packs页面下载。 - **Freesound Loops 4k (FSL4)**：本数据集包含从Freesound平台选取的部分音乐循环。本数据集的详细配置说明见此处。 - **Giant Steps Key Dataset (GSKY)**：本数据集包含从Beatport选取的经调式标注的预览音频。音频与原始标注可在此处获取。 - **Good-sounds Dataset (GSND)**：本数据集包含乐器样本的单声道录音。完整说明、原始标注与音频文件可在此处获取。 - **University of IOWA Musical Instrument Samples (IOWA)**：本数据集由爱荷华大学电子音乐工作室创建，包含乐器样本录音。可通过访问指定网站申请获取该数据集。 - **Mixcraft Loops (MIXL)**：本数据集包含Acoustica公司Mixcraft音乐软件中的部分音乐循环。获取这些循环需拥有对应软件的授权。本数据集的详细配置说明见此处。 - **NSynth Dataset Test and Validation sets (NSYT and NSYV)**：NSynth是由Google Magenta团队构建的大规模高质量带标注音乐音符数据集，采用合成声音制作。完整数据集说明（含原始标注与音频文件）可在此处获取。 - **Philharmonia Orchestra Sound Samples Dataset (PHIL)**：本数据集包含由Philharmonia Orchestra（爱乐管弦乐团）演奏家专门录制的数千个免费可下载声音样本。音频文件可从爱乐管弦乐团官网免费下载。 - **Freesound Single Events Dataset (SINGLE EVENT)**：本数据集包含从Freesound平台选取的部分音频片段，这些片段包含单音频事件或多音频事件。可使用CSV文件中提供的编号从Freesound平台下载单个音频片段以获取原始音频文件，可遵循本文所述的类似流程。
