TIME BASE
4 – 36 Typical Setup Examples
Digital Varispeed
We know Varispeed from analog tape machines. Time Base now enables
Varispeed for digital audio devices. This function should only be brought
into play in exceptional cases, principally in two areas:
Music
• A difficult-to-tune instrument needs to be accommodated by a few cents; or the
singer needs the track a semitone lower for recording.
The same advantages and disadvantages occur as when using an analog
tape machine, i.e. if playback is a tone lower, the track runs slower.
In such cases the MIDI instruments must be recorded first (as a rough
mix), as their pitch doesn't alter!
Film/Video
• 'After the fact' sound-to-picture synchronization, i.e. correction of sync errors
which have crept in during earlier stages in the work process.
A “manually synchronized” copy must be made, before further work can
be done.
The Varispeed is referenced to the selected Master Clock, and not just to
the internal crystal as on cheaper machines.
• The Varispeed range of digital audio devices is much narrower than on
analog tape machines. Some digital audio devices allow no Varispeed
whatsoever.
