# 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 | 13,651 | 90.7% |
| eval | 2,217 | 1,888 | 85.2% |
| **total** | **17,269** | **15,539** | **90.0%** |

35,183 clip-relative event rows in total. Every clip has at least one event.
`missing.tsv` lists the 1,730 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 |
|---|---:|---:|
| Alarm | 1,430 | 264 |
| Bark | 5,706 | 465 |
| Cough | 1,878 | 323 |
| Explosion | 1,036 | 168 |
| Gunshot | 3,114 | 321 |
| Laughter | 10,702 | 1,682 |
| Screaming | 1,215 | 246 |
| Vehicle horn | 1,729 | 250 |
| Whispering | 1,453 | 263 |
| Whistling | 2,598 | 340 |

`<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.
