Where to find the timestamp for each segmented audio clip?

According to the dataset description on the Zenodo, I suppose the timestamp for each audio clip should be included in the label.csv file. While within this file, only the clip index within a particular song can be found. Did you segment the whole song with equal length? If so what is the duration for each clip, otherwise, how can I determine the timestamp?

Hi,

1. For the timestamp information, please get the latest version of EMOPIA: EMOPIA 2.2. It contains a file called timestamps.json for easier usage. It records all the timestamps in dict format. The notebook scripts/load_timestamp.ipynb shows the format example. Or you can also access tagging_lists/ for timestamps of each file. Also, you can use scripts/timestamp2clip.py to get audio clips using timestamps.

2. We don't segment the whole song with equal length. We choose the segment with a specific emotion and try to cut the endpoint at the end of the music sentence. As a result, there might be 1 or more segments per song.

3. A reminder: if you want to use the data for full-song analysis, you might need to notice that there are a few songs that are actually playlists on YouTube. So if a song contains many segments (for example 10+), it might be a playlist from YouTube.

Thanks a lot for the quick update.
