{"url":"/dataset/warblr","name":"Warblr","full_name":null,"description_markdown":"**Warblr** is a dataset for the acoustic detection of birds. The dataset comes from a UK bird-sound crowdsourcing research spinout called Warblr. From this initiative the authors collected over 10,000 ten-second smartphone audio recordings from around the UK. The audio totals around 28 hours duration.\r\n\r\nThe audio covers a wide distribution of UK locations and environments, and includes weather noise, traffic noise, human speech and even human bird imitations. It is directly representative of the data that is collected from a mobile crowdsourcing initiative. Annotations of the Warblr dataset are performed by a network of volunteers.","description_withheld":null,"homepage":"http://machine-listening.eecs.qmul.ac.uk/bird-audio-detection-challenge/","introduced_date":"2016-08-11","introduced_date_note":null,"introduced_by":{"paper":null,"title":"Bird detection in audio: a survey and a challenge","first_author":null,"url":null},"license":{"name":"Unknown","url":null},"modalities":[{"name":"Audio","url":"/datasets/modality/audio"}],"tasks":[{"name":"Bird Audio Detection","url":"/task/bird-audio-detection","datasets_with_task":"/datasets/task/bird-audio-detection"}],"languages":[],"variants":["Warblr"],"data_loaders":[],"num_papers_in_archive":4,"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."}
