摘要:

最近,通过应用深度学习技术,在音频声源分离方面取得了重大进展。目前结合音频和视觉信息的方法使用2D表示(如图像)来指导分离过程。然而,为了从真实音乐合奏的记录(重新)创建用于3D虚拟/增强现实应用的声学上正确的场景,需要关于3D环境中的每个声源的详细信息。这一需求,以及LiDAR或rgb深度相机等3D视觉采集系统的激增,刺激了可以使用3D视觉信息指导音频分离的模型的创建。本文提出了一种多模态深度学习模型,以音乐表演记录的3D点云为条件执行音乐声源分离。该模型使用3D稀疏卷积提取视觉特征,而使用密集卷积提取音频特征。融合模块组合所提取的特征以最终执行音频声源分离。它示出,所提出的模型可以区分乐器从一个单一的三维点云帧,并执行声源分离定性类似的参考情况下,手动分配的仪器标签提供。

英文摘要:

Recently, significant progress has been made in audio source separation by the application of deep learning techniques. Current methods that combine both audio and visual information use 2D representations such as images to guide the separation process. However, in order to (re)-create acoustically correct scenes for 3D virtual/augmented reality applications from recordings of real music ensembles, detailed information about each sound source in the 3D environment is required. This demand, together with the proliferation of 3D visual acquisition systems like LiDAR or rgb-depth cameras, stimulates the creation of models that can guide the audio separation using 3D visual information. This paper proposes a multi-modal deep learning model to perform music source separation conditioned on 3D point clouds of music performance recordings. This model extracts visual features using 3D sparse convolutions, while audio features are extracted using dense convolutions. A fusion module combines the extracted features to finally perform the audio source separation. It is shown, that the presented model can distinguish the musical instruments from a single 3D point cloud frame, and perform source separation qualitatively similar to a reference case, where manually assigned instrument labels are provided.
