Starting the soundtrack in the middle of an mp3

Is there a way to start an mp3 in the middle somewhere for the Soundtrack?

In my video I want to start the mp3 at 20 seconds instead of at 0 (the beginning). Is this possible?

Thanks.

You can use the trim property on an audio asset to make it start 20 seconds later.

    "output": {
        "format": "mp4",
        "resolution": "sd"
    },
    "timeline": {
        "tracks": [
            {
                "clips": [
                    {
                        "asset": {
                            "src": "https://shotstack-assets.s3.amazonaws.com/music/moment.mp3",
                            "type": "audio",
                            "trim": 20,
                            "effect": "fadeInFadeOut"
                        },
                        "start": 0,
                        "length": 60
                    }
                ]
            }
        ]
    }
}
