Enhanced FLAC Metadata Manager

Overview

This is a PyQt6-based application designed to manage metadata for FLAC audio files. It allows users to create, update, delete, and apply metadata to individual files or entire folders.

Features

• File/Folder Selection: Select individual FLAC files or entire folders containing FLAC files for metadata management.
• Metadata List: Display metadata for selected files/folders in a list view, allowing users to easily navigate and edit metadata.
• CRUD Operations: Create new metadata items using Create, update existing items using Update, delete items using Delete, or apply changes to all selected files/folders using Apply to All.
• Error Handling: Display error messages when encountering issues during metadata processing.
• Metadata Editing: Edit individual metadata items by double-clicking on them in the list view.

Usage

Running the Application
