Audio Processor Pack

Edit, convert, and analyze audio files. Trim, merge, normalize volume, convert formats, and extract metadata — powered by pydub and ffmpeg under the hood.

Quick Start

agentnode install audio-processor-pack

from audio_processor_pack.tool import run

result = run(
    capability="process_audio",
    params={
        "input_path": "/tmp/recording.wav",
        "operations": [{"type": "convert", "format": "mp3"}]
    }
)
print(result["output_path"])

Usage

Trim silence and normalize

result = run(
    capability="process_audio",
    params={
        "input_path": "/tmp/podcast.wav",
        "operations": [
            {"type": "trim_silence", "threshold_dbfs": -40},
            {"type": "normalize", "target_dbfs": -16.0},
            {"type": "convert", "format": "mp3", "bitrate": "192k"}
        ]
    }
)

Merge clips with crossfade

result = run(
    capability="process_audio",
    params={
        "input_paths": ["/tmp/intro.mp3", "/tmp/main.mp3", "/tmp/outro.mp3"],
        "operations": [{"type": "merge", "crossfade_ms": 2000}]
    }
)

Extract audio metadata

result = run(
    capability="process_audio",
    params={
        "input_path": "/tmp/track.mp3",
        "operations": [{"type": "metadata"}]
    }
)
print(f"Duration: {result['duration_seconds']}s, Channels: {result['channels']}")

API Reference
