Nothing is uploaded — all in-browser. Tags are cut by byte surgery, never re-encoding: decoding and re-compressing already-lossy audio would lose quality for a cosmetic change. Cleaned files decode to identical samples.
Every map on this page uses these colours. The bar is the whole file end to end: metadata is everything a player walks past before the audio starts, the signed block is a cryptographic manifest such as C2PA, and structural bytes are the container's own scaffolding.
Small segments are widened so they stay visible, so widths are indicative — hover any segment for its true byte offsets.
Red is the opening click and nothing else: the burst at the very start of the audio that decays into silence before the music. It turns green once cleared, and blue where a payload of your own has been written into it.
Anything here has no editable counterpart above.
Removed — real metadata the writer drops; copy it now if you want it.
Kept — structure inside the audio stream, not a tag.
Not stored — read from the audio itself, so there is nothing to delete.
Every field with an editable counterpart now lives in the grid above, including WOAS.
