IOAI 2026 Home Task 1 - Dataset

This dataset is used for the IOAI 2026 Home Task 1 — a multi-class environmental sound classification competition.

Data Description

This competition uses short audio clips for a multi-class sound classification task. Each example is a .wav file located in the audio/ folder. The goal is to predict the integer class label for each evaluation audio clip.

The dataset contains 29 classes with labels from 0 to 28. The public training metadata is split across two CSV files:

• train.csv: base training classes, labels 0 to 15
• fine_tune.csv: additional training classes, labels 16 to 28

Both files use the same schema and can be combined for model training if desired.

Files

audio/

Contains all audio files used by the competition. All files are stored as .wav.

• Total files: 1,283

train.csv

Training metadata for labels 0 to 15.

• Rows: 491
• Splits: 296 train, 195 validation
• Columns:
  • path: relative path to the audio file
  • split: dataset split (train or val)
  • target: integer class label
  • category: human-readable class name

fine_tune.csv

Training metadata for labels 16 to 28.

• Rows: 792
• Splits: 624 train, 168 validation
• Columns:
