TonieToolbox allows you to create custom audio content for Tonie boxes by converting various audio formats into the specific file format required by Tonie devices. The tool provides several capabilities: - Convert single or multiple audio files into a Tonie-compatible format - Process complex folder structures recursively to handle entire audio collections - Analyze and validate existing Tonie files - Split Tonie files into individual opus tracks - Compare two TAF files for debugging differences - Support various input formats through FFmpeg conversion - Extract and use audio media tags (ID3, Vorbis Comments, etc.) for better file naming - Upload Tonie files directly to a TeddyCloud server - Automatically upload cover artwork alongside Tonie files
