{"url":"/dataset/jacappella","name":"jaCappella","full_name":null,"description_markdown":"**jaCappella** is a corpus of Japanese a cappella vocal ensembles (jaCappella corpus) for vocal ensemble separation and synthesis. It consists of 35 copyright-cleared vocal ensemble songs and their audio recordings of individual voice parts. These songs were arranged from out-of-copyright Japanese children's songs and have six voice parts (lead vocal, soprano, alto, tenor, bass, and vocal percussion). They are divided into seven subsets, each of which features typical characteristics of a music genre such as jazz and enka.\r\n\r\nSource: [jaCappella Corpus: A Japanese a Cappella Vocal Ensemble Corpus](https://arxiv.org/pdf/2211.16028v1.pdf)\r\n\r\nImage Source: [https://arxiv.org/pdf/2211.16028v1.pdf](https://arxiv.org/pdf/2211.16028v1.pdf)","description_withheld":null,"homepage":"https://tomohikonakamura.github.io/jaCappella_corpus/","introduced_date":"2022-11-29","introduced_date_note":null,"introduced_by":{"paper":"/paper/jacappella-corpus-a-japanese-a-cappella-vocal","title":"JaCappella Corpus: A Japanese a Cappella Vocal Ensemble Corpus","first_author":"Tomohiko Nakamura","url":null},"license":null,"modalities":[{"name":"Music","url":"/datasets/modality/music"}],"tasks":[{"name":"Audio Source Separation","url":"/task/audio-source-separation","datasets_with_task":"/datasets/task/audio-source-separation"},{"name":"Vocal ensemble separation","url":"/task/vocal-ensemble-separation","datasets_with_task":"/datasets/task/vocal-ensemble-separation"}],"languages":[{"name":"Japanese","url":"/datasets/language/japanese"}],"variants":["jaCappella"],"data_loaders":[],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
