How To Process a Million Songs in 20 Minutes, Here’s an example that’s not from the Nature paper, but a blog post titled We also hope to make new language features that make it easy for new users to easily explore the data set. Some tasks will require new algorithms, but many will involve repurposing existing database and analytics tools for a new context.įully solving these tasks involves a combination of distributed database techniques, linear algebra operations and time-series analysis. The goals of this use case are to take common MIR tasks and reimagine them in the context of a distributed database for scalability. However, to easily analyze music metadata at scale, we believe a different approach is necessary. These tasks are usually handled in MIR libraries in languages like Python. The paper’s methods illusistrate some common tasks in MIR, such as beat-aligning features, song transposition,Īnd setting parameters by sampling and gathering statistics. The information was extracted using EchoNest.Ī 2012 Nature Paper analysed musical trends across decades using
The data setĬonsists of song tags, track information, extracted audio information (such as beats, pitches, timbre, song sections), and other metadataĪbout one million songs. The largest data public data set for MIR tasks is the Million Song Dataset. MIR tasks span a variety of tasks, including recommendation systems, song tagging, mood detection, musicology and historical Music Information Retrieval (MIR) is a general term for analyzing musical audioĪnd metadata.
