[puzzle9]

Is there an existing issue for this?

• I have searched the existing issues

music-metadata version

v11.12.3

Current Behavior

Only by setting duration to true can the time be calculated

{
    "cover_path": null,
    "format": {
        "tagTypes": [
            "ID3v2.4"
        ],
        "trackInfo": [],
        "lossless": false,
        "hasAudio": true,
        "hasVideo": false,
        "container": "MPEG",
        "codec": "MPEG 2 Layer 2",
        "sampleRate": 22050,
        "bitrate": 8000,
        "codecProfile": "CBR",
        "numberOfChannels": 2,
        "numberOfSamples": 717835392,
        "duration": 32554.89306122449
    },
    "track": {
        "no": null,
        "of": null
    },
    "disk": {
        "no": null,
        "of": null
    },
    "movementIndex": {
        "no": null,
        "of": null
    },
    "title": "越走越远",
    "artists": [
        "吴克群"
    ],
    "artist": "吴克群",
    "album": "数星星的人"
}

Expected Behavior

吴克群 - 越走越远.001.zip
吴克群 - 越走越远.002.zip

Volume compression requires changing the name to. zip.001. zip.002

Attached audio sample?

Only by setting duration to true can the time be calculated.

That is by design if the duration can only be determined bv parsing the entire file.
