SACD ISO Patcher

• Automatic text-encoding detection for Chinese, Japanese and Korean titles. When you import from Discogs or MusicBrainz, the app recognises the encoding the disc needs (Shift-JIS, GB, Big5, KSC) and creates the right text channel in one click. A character that does not fit the disc's encoding now becomes a "create the right channel" action instead of a dead-end refusal.
• Bring self-made discs up to standard. SACD-R discs that declare a text channel but store no text in it (a standards violation) are now detected when you open them and fixed with one "bring to standard" click; the command-line version has a --normalize flag.
• Japanese wave dash. Titles containing the wave dash 〜 (for example "...〜snow a cappella〜") now encode and import correctly - previously this character blocked saving the track.
• Many encoding-detection accuracy improvements: the disc's region (not guesswork) decides Traditional vs Simplified Chinese; an unambiguous encoding is applied confidently without extra prompts; clearer import messages.

Like most useful tools, this one was born from irritation.

Some music-player libraries are pedantic in the worst way. Write the same artist in two different letter-cases on two discs - Keith Jarrett here, KEITH JARRETT there - and they will quietly file them as two strangers who happen to share a name, scattering one artist across your collection.

And then there are the discs themselves. Many early SACDs arrived almost mute: no track titles, a missing year, an absent catalog number, a performer left off entirely - just Track 1, Track 2, Track 3 where a whole program of music should be.

You could re-rip and re-author a multi-gigabyte image to fix a single typo - or you could reach inside the disc image and correct the words directly, leaving every audio sample exactly where it was. That second idea became SACD ISO Patcher.
