Error when reading metadata

[athenasyarifa]

Hi Nilo,

It's me again, sorry. I am trying to load my audio files, and segment them using annotations in Raven format (one for each audio file). I made a custom parser for this to return a SegmentAnnotation class object as you instructed in the tutorial. Then, when I have the filepaths for each .wav and the associated .txt file, I tried using the segment_files function to segment the audio files. It raises a ParseError when trying to read the metadata of the .wav file (see below).

File [~/anaconda3/envs/pykanto_env_2/lib/python3.9/site-packages/pykanto/signal/segment.py:467](https://vscode-remote+wsl-002bubuntu.vscode-resource.vscode-cdn.net/mnt/c/Users/Lenovo/Documents/GitHub/willowtit-project/bioacoustic/~/anaconda3/envs/pykanto_env_2/lib/python3.9/site-packages/pykanto/signal/segment.py:467), in segment_files(datapaths, wav_outdir, json_outdir, resample, parser_func, pbar, **kwargs)

ValueError: year 0 is out of range

My scripts are the following:

segment_files(
    files_to_segment, 
    json_outdir="/mnt/c/Users/Lenovo/Documents/GitHub/willowtit-project/bioacoustic/data/segmented/willowtit_syllables/JSON",
    wav_outdir="/mnt/c/Users/Lenovo/Documents/GitHub/willowtit-project/bioacoustic/data/segmented/willowtit_syllables/WAV",
    resample=None, 
    parser_func=parse_raven_annot,
    min_duration=3,
    min_freqrange=100
)

I am working with XC audio recordings, and when I checked the metadata of a first wav file using ReadWav(wav_filepaths[0]).all_metadata, it looks like this:

<WAVE({
    'filepath': '/mnt/c/Users/Lenovo/Documents/GitHub/willowtit-project/bioacoustic/willowtit_syllables/Poecile-montanus-130402-cut-1.wav',
    'filesize': '2.35 MiB',
    'pictures': [],
    'streaminfo': <WAVEStreamInfo({
        'audio_format': <WAVEAudioFormat.PCM>,
        'bit_depth': 16,
        'bitrate': '706 Kbps',
        'channels': 1,
        'duration': '00:28',
        'sample_rate': '44.1 KHz',
    })>,
    'tags': <ID3v2Frames({
        'album': ['xeno-canto'],
        'artist': ['Jelmer Poelstra'],
        'comment': [
            <ID3v2Comment({
                'description': '',

How can I fix this? Should I edit the metadata according to how your script parse it? I would be really grateful for your suggestion when you have time!

Best,
