JazzSAMBA
收藏资源简介:
JazzSAMBA是首个面向爵士标准曲的多轨音频数据集,由加州大学圣地亚哥分校与麻省理工学院联合构建。该数据集包含76首标准曲,涵盖8位音乐家演奏的鼓、贝斯、钢琴、小号及萨克斯等乐器,总时长约16.1小时,分为异步(分轨录制)和同步(乐队合奏)两种录制协议,并提供首选与备选录音选择。数据创建过程中,音乐家按标准曲目先进行异步分轨录制,随后同步合奏,并手动标注小节、和弦、段落及独奏者信息。该数据集旨在支持图表条件伴奏、爵士乐队源分离以及形式感知音乐信息检索等任务,弥补了爵士乐领域此前缺乏高质量、多轨标注数据集的空白。
JazzSAMBA is the first multi-track audio dataset dedicated to jazz standards, jointly constructed by the University of California, San Diego and the Massachusetts Institute of Technology. This dataset includes 76 jazz standard compositions, with performances of instruments such as drums, bass, piano, trumpet, and saxophone by 8 musicians, totaling approximately 16.1 hours of audio content. It features two recording protocols: asynchronous (track-by-track recording) and synchronous (full band ensemble performance), and provides both preferred and alternative recording options. During the dataset construction phase, musicians first completed asynchronous track-by-track recordings for each composition, followed by synchronous band ensemble performances, and manually annotated metadata including measure boundaries, chord progressions, musical section boundaries, and soloist identities. This dataset aims to support tasks such as score-conditioned accompaniment, jazz ensemble source separation, and form-aware music information retrieval, addressing the critical gap in the jazz music domain where high-quality, multi-track annotated datasets were previously lacking.

数据集规模
- 总曲目数:76 首
- 异步曲目:50 首
- 同步曲目:26 首
- 音乐家数量:8 人
数据集特点
- 同一曲目库采用双重录制协议(异步 vs 同步)
- 每首曲目包含首选与备选两个 take 层级(混音与分轨层面均提供)
- 多层标注(小节、和弦、段落、独奏者)基于统一小节网格
- 提供钢琴的 ground-truth MIDI(异步曲目亦包含鼓),并明确标注派生的 AMT/debleed
- 异步曲目包含小号与一支萨克斯(中音或次中音,不同时包含),鼓最先录制,后续乐器顺序可变
- 同步曲目为全乐队共同录制,每次 take 单独标注
- 首选混音上的标注会复制到备选层级
标注与数据说明
- 标注基于共享小节网格进行对齐
- 1 与 2 分别表示首选与备选 take 层级
- 异步曲目包含小号及一支萨克斯(中音或次中音,二者不并存)
- 同步曲目包含小号和/或萨克斯,全乐队同步录制
特色混音示例
提供首选 take 混音的一分钟片段,降采样至 24 kHz / 192 kbps,并附分轨。
