| # AudioSet-Strong-10 |
|
|
| A ten-class, strong-label, 10-second-clip subset of **AudioSet-Strong**, with |
| clip-relative event onsets and offsets. Built for streaming / bounded-latency |
| sound event detection, where you need per-event times rather than clip tags. |
|
|
| ## Classes |
|
|
| | Class | AudioSet MID | |
| |---|---| |
| | Alarm | `/m/07pp_mv` | |
| | Bark | `/m/05tny_` | |
| | Cough | `/m/01b_21` | |
| | Explosion | `/m/014zdl` | |
| | Gunshot | `/m/032s66` | |
| | Laughter | `/m/01j3sz` | |
| | Screaming | `/m/03qc9zr` | |
| | Vehicle horn | `/m/0912c9` | |
| | Whispering | `/m/02rtxlg` | |
| | Whistling | `/m/01w250` | |
|
|
| The official strong annotations contain **15,052 train** and **2,217 eval** |
| unique 10-second clips for these ten classes. |
|
|
| ## Coverage in this release |
|
|
| | Split | Official clips | In this release | Coverage | |
| |---|---:|---:|---:| |
| | train | 15,052 | 14,521 | 96.5% | |
| | eval | 2,217 | 2,161 | 97.5% | |
| | **total** | **17,269** | **16,682** | **96.6%** | |
|
|
| 37,832 clip-relative event rows in total. Every clip has at least one event. |
| `missing.tsv` lists the 404 segment ids that could not be retrieved from |
| YouTube or from the mirror (the underlying videos are deleted). |
|
|
| Event rows per class (train / eval): |
|
|
| | Class | train | eval | |

| | Bark | 6,014 | 541 | |
| | Cough | 2,032 | 368 | |
| | Explosion | 1,095 | 186 | |
| | Gunshot | 3,396 | 353 | |
| | Laughter | 11,250 | 1,918 | |
| | Screaming | 1,326 | 270 | |

| ## Contents |
|
|
| This repository releases **annotations and identifiers**, not audio: |
|
|
| ``` |
| train_events.csv path,onset,offset,label |
| eval_events.csv |
| missing.tsv official clips that were unavailable |
| short_windows.tsv clips whose source audio ends early |
| oversize_windows.tsv clips kept at full length |
| ``` |
|
|
| Event rows use paths of the form |
| `audio/<split>/<bucket>/<ytid>_<start_ms>.wav`, where `<bucket>` is the first |
| two hex digits of a CRC32 of the file stem. That is the layout the audio takes |
| in the companion repository, so the tables apply directly once the audio is |
| mounted there. |
|
|
| ## Audio |
|
|
| The audio lives in a companion repository, |
| `LakoreAI/AudioSet-Strong-10-audio` (16,682 clips, same layout), released for |
| research use subject to the rights of the original uploaders. The annotation |
| tables here apply to it unchanged. |
|
|
| `<ytid>_<start_ms>` is the official AudioSet `segment_id`: the YouTube id and |
| the start of the 10-second window in milliseconds. `onset`/`offset` are seconds |
| **inside the clip** (0-10), so a row is directly usable as a strong label. |
|
|
| One clip can have several rows (several labelled events). Every clip has at |
| least one event from the ten classes above; other AudioSet classes that occur |
| in the same window are not annotated here. |
|
|
| ## Provenance and completeness |
|
|
| 1. Segment ids, labels and event times come from the official |
| `audioset_train_strong.tsv` / `audioset_eval_strong.tsv` |
| (`storage.googleapis.com/us_audioset`), filtered to the ten MIDs. |
| 2. Audio is the 10-second window containing the labelled event, downloaded |
| from YouTube with `yt-dlp` and resampled to 16 kHz mono. |
| 3. Clips whose YouTube video is deleted are recovered from the public |
| `CLAPv2/audioset_strong` mirror (same official windows). Annotation times |
| still come from the official TSVs; the mirror only supplies audio bytes. |
| Harvested clips were cross-checked against the mirror's own event list |
| (zero label mismatches). |
|
|
| YouTube attrition is real: a share of the official videos is permanently |
| unavailable. `missing.tsv` lists the segment ids that could not be obtained |
| from either source at build time. Coverage is reported in the dataset card |
| table below and should be re-checked before any comparison with published |
| numbers on the complete strong set. |
|
|
| ## Licence and credit |
|
|
| - Annotations: **CC BY 4.0**, Google AudioSet (Gemmeke et al., 2017). |
| - Audio: downloaded from YouTube; rights remain with the original uploaders. |
| This repository grants no rights over the audio and is released for research |
| use, mirroring how AudioSet itself distributes the corpus. It may be removed |
| on request. |
| - The ten-class selection follows the AudioSet-Strong subset used by the |
| RED+EPN line of work (Schmid et al.). |

|
| ## Clips whose source audio is short or over-long |
|
|
| 183 clips in `audio_oversize/` are kept exactly as downloaded: the source audio runs past the 10 s window, so they cannot enter the labelled corpus, but they are not discarded. |
| Clips whose source audio ends slightly before the window are padded with silence to 10.00 s; their true length is listed in `short_windows.tsv` and the events are clipped to it. |
|
|
| ### Why clips are missing |
|
|
| Each missing clip was checked with a metadata request. Of the 404: |
|
|
| - **218** deleted or unavailable at the source |
| - **125** private |
| - **59** removed (copyright) |
| - **2** other errors |
|
|
| None is recoverable: the videos no longer exist in any accessible form, so no |
| credential or client can fetch them. `missing_reasons.tsv` lists the per-clip cause. |
