Taguar 

A small desktop app for browsing a directory of audio files and editing their ID3v2 / primary metadata tags. Built with Iced and lofty.

Features

• Select a directory via file dialog or pass one on the command line
• Recursive scan for audio files (mp3, flac, m4a, m4b, mp4, ogg, opus, oga, wav, aiff, aif, aifc, wv, ape)
• Left-pane table: Filename (relative path), Artist, Title, Comment; proportional columns that adapt to window size
• Right-pane sidebar: compact form for Title, Artist, Album, Album Artist, Year, Track, Genre, Composer, Comment, Disc Number, Compilation flag
• Embedded cover art preview with dimensions, size, MIME and picture type
• Read-only ID3v1 section shown when a file has an ID3v1 tag (ID3v1 is never written back)
• Save writes through lofty's TagExt::save_to_path — for MP3/WAV/AIFF this is ID3v2, for FLAC / OGG / M4A it's the format's native primary tag
• Built-in audio playback via rodio with a Play / Pause button above the Title field
• Bottom status bar showing selected-file and total duration + size

Running

cargo run --release                                  # opens with a dir picker
cargo run --release -- /path/to/music                # opens that directory
cargo run --release -- --help                        # print usage

Format support

Playback goes through rodio with symphonia-all, which covers MP3, FLAC, Vorbis, WAV/PCM/ADPCM, and AAC inside MP4/M4A containers. Symphonia 0.5 has no working Opus decoder yet, so .opus files are routed through a dedicated decoder built on libopus (bundled via the opus crate) plus the ogg crate for container parsing.
