This guide presumes you have Toast Titanium 17 or 18 (the “1720” in your query likely refers to a version/build or a bundled extra pack). The principles apply to v19 and v20 as well.

: It supports high-resolution audio formats like FLAC and Ogg Vorbis that standard QuickTime might not handle, and it allows for archiving original photos without loss of quality.

Following this guide, Toast Titanium will produce burns that are visually indistinguishable from source and more durable than default “fast” burns. For archival projects, consider burning two copies on different brand media.
