# Onset dataset

This dataset is described in [1][1].

## Contact:

Sebastian Böck <sebastian.boeck@jku.at>

## Description:

Collection of 321 audio excerpts with onset annotations.

## Content:

```
audio/                  original audio files converted to .flac format
annotations/onsets/     onset annotations
annotations/giantsteps/ annotations in the GiantSteps project format
annotations/.git/       git repo with annotations 
splits/                 file splitting definitions
```

To convert the audio files to .wav use 'flac -d *.flac'
