MATS - Multi-Annotator Tagged Soundscapes

This is a dataset containing audio tags for a number of 3930 audio files of the TAU Urban Acoustic Scenes 2019 development dataset (airport, public square, and park). The files were annotated using a web-based tool, with multiple annotators providing labels for each file. 

The dataset contains annotations for 3930 files, annotated with the following tags:

• announcement jingle
• announcement speech
• adults talking
• birds singing
• children voices
• dog barking
• footsteps
• music
• siren
• traffic noise

The annotation procedure and processing is presented in the paper:

Irene Martin-Morato, Annamaria Mesaros. What is the ground truth? Reliability of multi-annotator data for audio tagging, 29th European Signal Processing Conference, EUSIPCO 2021 

The dataset contains the following:

• raw annotations provided by 133 annotators, multiple opinions per audio file
