Synchronization
Synchronization is very important to an audio system, since it is necessary to
align playback and recording speeds of different system components.
Synchronization enables studio equipment such as tape machines, drum
computers, video recorders, or sequencers to be linked with different formats
like MIDI clock, MIDI timecode, or SMPTE timecode so that all of the devices
run at precisely the same time.
Samplitude 11.5 Producer can be configured to as the master or slave within a
synchronization system. As a master program, it generates the necessary
timing information required for other system components; as slave. Samplitude
11.5 Producer receives the timecode data to follow during playback or
recording.
Clock on digital systems
In case digital signal flows are processed, e.g. via ADAT, SPDIF, or MADI, it is
important to define a clock reference within the overall system. The clock
signal is transferred via Blackburst, World Clock, or the digital input, and it may
be received by the receiving or playback computer. External devices such as
converters or mixers may also provide a clock reference. For these systems,
there can be only one master but several slaves.
Note: Don't confuse (Word) clock with timecode. The clock signal is only a
digital pulse for comparison of the timing between the connected devices and
to keep the bit rate constant. This enables transmission errors to be prevented.
Professional digital audio devices normally feature a word clock input and are
able to generate and receive a clock signal.
Time-related synchronization of projects
For more complicated configurations, it is usually necessary to connect various
audio and video systems via absolute time references. This enables them to
operate according to the behavior of the master, and the timecode information
(transport and progress) is implemented correspondingly.
Synchronization formats
There are different types of synchronization formats. In the synchronization
format you will find slave device information about the start position, start and
