The downside is that server costs have doubled.Ī new algorithm has been added Ultimate Vocal Remover (UVR). As a result, the waiting queues have decreased and there are fewer errors associated with a lack of GPU memory. Positive effect - the video card has been changed to a more powerful one with more memory. We had to move to a new server due to lack of space on the old one. Similarly, for the score-informed version, check the zenodo page.News : We have three big news: The separation results and the computed metrics with BSS Eval can be found on the zenodo page.
TRACK SEPARATOR HOW TO
The uploaded datapack will comprise the separated tracks.Ĭode and detailed instructions on how to reproduce experiments in part four (source separation using deep learning) can be found on the associated github repository. You need to create a datapack with datapack designer, upload it and select the checkbox which computes the source separation. However, multi-channel score-informed source separation can be computed using the Repovizz website. We do not have the rights to distribute the NMF framework and to some extent note refinement is integrated with this framework.
TRACK SEPARATOR CODE
The note refinement code in part three of the thesis is on github. The Bach10 recordings synthesized with Sibelius can be found on the zenodo repository. We denoised the original recordings and annotated each of the tracks corresponding to the instrument groups. We propose the PHENICX-Anechoic dataset which relies on the Aalto orchestral anechoic recordings.
TRACK SEPARATOR SOFTWARE
Most of this work follows the research reproducibility principles, inasmuch the datasets, code, software prototypes, published papers, and project reports are made available along with the necessary instructions. In addition, in the fifth part, we introduce a cloud-based source separation software architecture and the associated applications. With respect to that, we aim at overcoming data scarcity in the case of supervised source separation approaches by taking advantage of the traits of this music tradition to generate better data to train neural networks. Furthermore, while we work towards improve existing separation frameworks, in the fourth part of the thesis we propose a low latency framework relying on deep learning. In the third part of the thesis, our contributions are towards fixing context-specific problems encountered in score-informed source separation, like the errors in the alignment between a score and the associated renditions. Towards an objective evaluation, in the second part of the thesis we propose an orchestral music dataset accompanied by score annotations and an evaluation methodology which assesses the influence of difference parts of the separation framework. This scenario is known in literature as score-informed source separation. In addition, since scores are commonly available for orchestral pieces, we leverage this information to further improve the separation. For orchestral music the instruments are known, and we train timbre models for each instrument, a case commonly known as timbre-informed source separation. In fact, the more information we have about a music piece, %the more we can restrict our model, and

Music source separation improves if we know which instruments are present in the piece, and if we have the score e.g. Additionally, the separated instrument tracks can be further analyzed by other music information research algorithms which perform better on these signals than on the audio signal of the mixture. Being able to separate the audio corresponding to the instruments allows for interesting applications such as focusing on a particular section in the orchestra or re-creating the experience of a concert in virtual reality. This thesis is concerned with source separation of Western classical music mixtures, namely orchestral music.

This signal processing task is commonly known as audio source separation and involves recovering the sources which are mixed together in a combined signal.

However, it is a difficult task to teach a computer to automatically separate the acoustic scene into sources and solely focus on specific elements. Humans are able to distinguish between various sound sources in their environment and selectively attend to specific ones.
