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.
