1. Do not convert (Default behavior)
Keeps the exact original Container and Codec of the file you dropped in (either .mp3 or .m4a), it just rapidly modifies the metadata headers without touching the audio stream at all.
2. MP3
• Container: MP3 (.mp3 file extension)
• Audio Codec: MP3 (encoded via libmp3lame)
• Metadata Format: ID3v2.3 (specifically enforced so cover art and tags show up correctly in most players)
3. M4A (Standard)
• Container: MPEG-4 / MP4 Audio (.m4a file extension)
• Audio Codec: AAC (Advanced Audio Coding, which is the standard lossy format used by Apple/iTunes)
• Metadata Format: MP4/QuickTime standard tags
4. FLAC
• Container: FLAC (.flac file extension)
• Audio Codec: FLAC (Free Lossless Audio Codec)
• Metadata Format: Vorbis Comments (the native tagging system for FLAC files)
5. ALAC
• Container: MPEG-4 / MP4 Audio (.m4a file extension)
• Audio Codec: ALAC (Apple Lossless Audio Codec)
• Metadata Format: MP4/QuickTime standard tags (same as standard M4A)
