Time-transform Extension¶
Describe a standard set of time transforms:
deals with:
- timestamps
- modifying the timebase
- setup time-based processes
Framebased stream storage in files needs a way to describe time.
Timestamps should be used on blocks of simultaneous spatDIF information.
/spatdif/time/ 1000 ms /spatdif/time/ 1.2 (seconds are default)
Q: Timeunits?
standard time is described in seconds since beginning of the piece. (double)
Q: How is the interaction/overlap with other extensions such as event, media, or interpolation extension?
time is integral part of the core entities and used throughout extensions
this time-transform extension is used to change the time-base of events, groups of events and other time-based elements such as trajetories.
