This tool processes audio files to professional broadcast standards, ensuring consistent volume levels across your audio collection.\n\n## Features\n\n- Normalizes audio files to -13 LUFS (Loudness Units Full Scale)\n- Supports multiple audio formats (MP3, WAV, FLAC)\n- Preserves audio quality while adjusting loudness\n- Provides detailed processing feedback and debugging information\n- Includes loudness verification after processing\n- Maintains original sample rate (44.1kHz)\n\n## Prerequisites\n\n- macOS with Homebrew installed\n- FFmpeg installed via Homebrew (`brew install ffmpeg`)\n- Node.js installed on your system\n\n## Installation\n\n1. Clone this repository:\n```bash\ngit clone https://github.com/renderghost/normal.git\ncd normal\n```\n\n2. Make sure you have FFmpeg installed:\n```bash\nbrew install ffmpeg\n```\n\n## Usage\n\nRun the script and follow the interactive prompt:\n\n```bash\nnode normal.js\n```\n\nWhen prompted, enter the path to your audio file. The tool will:\n1. Analyze the current loudness of the file\n2. Process the audio to achieve -13 LUFS\n3. Verify the resulting loudness\n4. Replace the original file if the normalization was successful\n\n## Technical Details\n\n- Target Loudness: -13 LUFS\n- Loudness Range (LRA): 7\n- True Peak: -1 dBTP\n- Sample Rate: 44.1kHz\n- Supported Formats: MP3, WAV, FLAC\n\n## How it Works\n\n1. **Input Validation**: The tool first checks if the input file exists and is in a supported format.\n\n2. **FFmpeg Processing**: Uses FFmpeg's `loudnorm` filter with these parameters:\n- Input Loudness (I): -13 LUFS\n- Loudness Range (LRA): 7\n- True Peak (TP): -1 dBTP\n\n3. **Verification**: After processing, the tool:\n- Creates a temporary normalized file\n- Measures its loudness using EBU R128 standards\n- Verifies the result is within ±1 LUFS of the target\n- Only replaces the original if verification passes\n\n4. **Cleanup**: Removes temporary files and provides detailed feedback about the process.\n\nThe tool includes extensive error handling and debugging information to help troubleshoot any issues that may arise during processing.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frenderghost%2Fnormal","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frenderghost%2Fnormal","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frenderghost%2Fnormal/lists"}
