# Annotation Files
There are three types of group metatdata files:
>"metadata.csv"
    >Metadata provided by each group is in a different format, and contains types of information specific to that group that are not included in "metadata_overall.csv"
>"recordings.csv"
    >List of "song_code" values for each recording. These are used consistently across all file types.
>"transcribers.csv"
    >List of "transcriber_code" values (one per transciber) for each group. These are used consistently across all file types.


# Annotation Files

There are four types of annotation files:
>"{song_code}__{transcriber_code}__pitches.csv"
    >Fundamental frequency, estimated by pYIN, and manually corrected using the Tony software.
>"{song_code}__{transcriber_code}__segments.csv"
    >Note-level annotation (onsets, durations, note pitch), manually annotated using Tony.
    >Note pitch is the automatically-assigned value provided in Tony.
>"{song_code}__{transcriber_code}__notes.csv"
    >The same note-level annotation as in "...segments.csv", but with note pitch manually corrected using SonicVisualizer.
>"{song_code}__{transcriber_code}__level.csv"
    >Volume level annotations, with timestamps matched to "...pitches.csv".
