ESMUC Choir Dataset
收藏资源简介：
ESMUC Choir Dataset is a multi-track dataset of Western choral music that contains individual audio recordings of 12 singers, all of them undergraduate students in vocal performance at Escola Superior de Música de Catalunya (ESMUC), the professional music school in Barcelona (Spain), at the time of recording. ECD is released as part of the following Ph.D. dissertation: Helena Cuesta. Data-driven Pitch Content Description of Choral Singing Recordings. PhD thesis, Universitat Pompeu Fabra. 2022 (to appear). Singers are unevenly distributed into Soprano, Alto, Tenor, and Bass (SATB) sections and were recorded simultaneously. A close-up microphone captured each voice, and the whole choir sound was captured by two stereo room microphones placed at two different distances from the singers. ECD comprises all audio files from the multi-track recording and manually corrected annotations of F0 contours and notes. ECD includes the following pieces: Die Himmel erzählen die Ehre Gottes (Op. 11, SWV 386), written by Heinrich Schütz (Germany, 1585-1672). Der Greis, written by Franz Joseph Haydn (Austria, 1732-1809). Seele Christi, heilige mich, written by Anton Heiller (Austria, 1923-1979). All singers' tracks are mono audio files, and the two room mics are stereo, all using a sampling rate of 44 100 Hz. The total duration of accumulated audio for the entire dataset is roughly 31 minutes. ECD contains three songs, two of them recorded in shorter parts, as well as some brief voice warm-up exercises. For each of the songs, the dataset presents three modalities: Full takes (FT), where the song (or song part) is performed from beginning to end by the entire choir. Isolated section (IS), where some sections are recorded in isolation (other sections are silent) performing parts of the songs. Short excerpts (SE), which are short passages of the songs, mostly performed to practice challenging parts, performed by the full choir. Songs and warm-up exercises are organized in Takes, which are numbered, i.e., take1 or take3. For the IS setting, filenames refer to the choir section. Similarly, the short passages are indicated by SE and the passage number. Finally, we denote each singer using S/A/T/B and a number, e.g., T3 refers to the third tenor. All audio tracks from the dataset, except the room microphones, have two associated annotation files: one for the F0 contour, and a second one with the note annotations. Tracks from the warm-up exercises only have F0 contours, since there is no associated score to them. A README file accompanies the dataset with specific information about the filenames. All dataset files and the README are compressed in the provided zip file. Special cases: Die Himmel has two soprano parts and two tenor parts. In the dataset: Soprano part 1 is sung by S1 and S2 Soprano part 2 is sung by S3, S4, and S5 Tenor part 1 is sung by T1 and T2 Tenor part 2 is sung by T3 For some takes, singers from different sections were mixed (e.g., randomly distributed and not grouped by section). These are the takes: DG_take3 DG_take4 SC3_take2 SC2_take3 SC1_take3 SC1_short1 SC1_short2 SC3_short6 SC3_short7 Known issues: The annotation file SC1_FT_take3S1.f0 has a mistake in the filename and should be SC1_FT_take3_S1.f0
ESMUC合唱团数据集（ESMUC Choir Dataset）是一套多轨西方合唱音乐数据集，收录了12名歌手的独立音频录音。所有歌手均为录音录制期间，西班牙巴塞罗那专业音乐院校加泰罗尼亚高等音乐学院（Escola Superior de Música de Catalunya, ESMUC）声乐表演专业的本科生。 ECD作为以下博士学位论文的附属数据集发布：Helena Cuesta. 《合唱录音的音高内容数据驱动描述》，庞培法布拉大学博士论文，2022年（待出版）。 歌手被不均匀地分配至女高音（Soprano）、女低音（Alto）、男高音（Tenor）与男低音（Bass，合称SATB）声部，并采用同步录制方式。每名歌手的人声由一支近距麦克风收录，整体合唱团的声音则由两支与歌手间距不同的立体声房间麦克风采集。 ECD包含多轨录音的全部音频文件，以及经人工校正的基频（F0）轮廓与音符标注。 ECD收录的曲目如下： - 《Die Himmel erzählen die Ehre Gottes》（作品11，SWV 386），海因里希·许茨（Heinrich Schütz，德国，1585-1672）创作； - 《Der Greis》，弗朗茨·约瑟夫·海顿（Franz Joseph Haydn，奥地利，1732-1809）创作； - 《Seele Christi, heilige mich》，安东·海勒（Anton Heiller，奥地利，1923-1979）创作。 所有歌手的音轨均为单声道音频文件，两支房间麦克风的音轨为立体声格式，所有音频的采样率均为44100 Hz。整个数据集的累计音频总时长约为31分钟。 ECD包含三首歌曲，其中两首被拆分为较短段落录制，同时还包含若干简短的人声热身练习片段。 针对每首歌曲，数据集提供三种模态： - 完整录制（Full Takes, FT）：由整个合唱团从头至尾完整表演歌曲（或歌曲段落）的音轨； - 孤立声部（Isolated Section, IS）：仅单独录制指定声部（其余声部保持静音）以表演歌曲片段的音轨； - 短节选（Short Excerpts, SE）：由整个合唱团表演的歌曲短段落，大多用于练习高难度乐句。 歌曲与热身练习均按录制场次（Takes）进行编号命名，例如take1或take3。对于孤立声模态（IS），文件名会标注对应的合唱团声部。类似地，短节选会以SE和段落编号进行标识。最后，我们以S/A/T/B加编号指代每名歌手，例如T3即指第三名男高音歌手。 除房间麦克风音轨外，数据集中所有音频音轨均配有两份关联标注文件：一份为基频轮廓标注，另一份为音符标注。热身练习的音轨仅配有基频轮廓标注，因其无对应乐谱。 数据集随附一份README文件，详细说明文件名的具体命名规则。所有数据集文件与README均打包在提供的ZIP压缩包中。 特殊说明：《Die Himmel》包含两个女高音声部与两个男高音声部，在本数据集中： - 女高音声部1由S1与S2演唱； - 女高音声部2由S3、S4与S5演唱； - 男高音声部1由T1与T2演唱； - 男高音声部2由T3演唱。 部分录制场次中，不同声部的歌手被混合录制（例如随机分布而非按声部分组），这些场次包括：DG_take3、DG_take4、SC3_take2、SC2_take3、SC1_take3、SC1_short1、SC1_short2、SC3_short6、SC3_short7。 已知问题：标注文件SC1_FT_take3S1.f0存在文件名错误，正确文件名应为SC1_FT_take3_S1.f0。
