Source hierarchy
Official documentation describes available features and restrictions. Technical manuals help explain processing tradeoffs. A product homepage can support what a vendor advertises; it cannot independently establish how well that product works. Dates identify when a page was published or revised, not a promise that an external source cannot change.
Reading illustrations and examples
The waveform-style graphic on our homepage is a schematic listening workflow, not recorded audio or before-and-after measurements.
How to use these guides
Keep original exports, make reversible changes, and compare at a similar listening level. Stop a repair when it costs more detail than it restores. Check current service rules and the receiving party’s requirements before distribution. Read our recommendation standards.
