论文摘要
数据是现代机器学习系统的命脉，包括音乐信息检索中的命脉（MIR）。但是，MIR长期以来一直被小型数据集和不可靠的标签所困扰。在这项工作中，我们建议使用生成建模打破这种瓶颈。 By pipelining a generative model of notes (Coconet trained on Bach Chorales) with a structured synthesis model of chamber ensembles (MIDI-DDSP trained on URMP), we demonstrate a system capable of producing unlimited amounts of realistic chorale music with rich annotations including mixes, stems, MIDI, note-level performance attributes (staccato, vibrato, etc.), and even fine-grained synthesis参数（音高，振幅等）。我们称此系统为室内集合发生器（CEG），并使用它来生成来自四个不同腔室合奏（cocochorales）的大型合唱。我们证明了使用我们的方法生成的数据改善了音乐转录和源分离的最新模型，并且我们将系统和数据集释放为Mir社区未来工作的开源基础。
Data is the lifeblood of modern machine learning systems, including for those in Music Information Retrieval (MIR). However, MIR has long been mired by small datasets and unreliable labels. In this work, we propose to break this bottleneck using generative modeling. By pipelining a generative model of notes (Coconet trained on Bach Chorales) with a structured synthesis model of chamber ensembles (MIDI-DDSP trained on URMP), we demonstrate a system capable of producing unlimited amounts of realistic chorale music with rich annotations including mixes, stems, MIDI, note-level performance attributes (staccato, vibrato, etc.), and even fine-grained synthesis parameters (pitch, amplitude, etc.). We call this system the Chamber Ensemble Generator (CEG), and use it to generate a large dataset of chorales from four different chamber ensembles (CocoChorales). We demonstrate that data generated using our approach improves state-of-the-art models for music transcription and source separation, and we release both the system and the dataset as an open-source foundation for future work in the MIR community.
