PT3 to SIX conversion is the process of transforming a file encoded in the PT3 format into the SIX format so the content can be opened, edited, or distributed by applications that require SIX. This conversion remaps PT3's container/structure and metadata into SIX's expected layout while preserving as much original data and fidelity as possible.
