Current measured results by file format.

Fusion compression performanceFusion uses a self-referencing trail adapted to each format. Its newer PNC-ATRL architecture represents that trail as connected nodes that can share structure and rebuild the original data exactly. These results come from recorded workloads, with market standards named wherever Fusion beat them.

06 / MEASURED EVIDENCEThe current WAV profile tests whole-predecessor, split-stream, frame-dictionary, role-lane and metadata/residual node programs, then retains the smallest complete exact package.

67.21% saved

01The current fresh six-file workload produced 35,298 bytes from 107,664 source bytes.

68.06% saved

02The independent one-second workload produced 61,345 bytes from 192,044 source bytes.

Exact recovery across both workloads

03The current profile improved on its authenticated predecessor and has matching Python and .NET package support.

Different files create different opportunities.

08 / MEASURED EVIDENCELarge savings often come from repeated files or reusable parts across a collection. Already-compressed audio and video usually leave less room. Fusion understands the format and applies its trail where it adds value.
