Firstly, both radio playout systems are good. They just have a different set of features, and strengths and weaknesses.
Things Zetta has over SPL:
- Ability to script the loading of audio
- Multi-User customisation and granular permissions
- Real-time manipulation of the playout log over network from any Zetta computer
- A truly networked system
- Completely database driven system
- Multiple redundancy points
- Connectivity with multiple Zetta sites/offices.
- Cross Platform IVT – through web browser with Zetta2Go
- Visual Segue Editor for the log
- Visual Cue audio editing on files
- Can run multiple stations from the same database
- A non-fixed location database
- Built-in Audio Editor
- Multipoint audio ducking for segues
- World wide team of 24/7 support
- Better on-air sound
- Better integration of the Library of songs, links and ads in the system as a whole
When integrated with GSelector as the scheduler:
- Granular hourly depart restrictions
- Unscheduling and scheduling of specific categories
- Complicated Artist separation
- Programming can be scheduled from any computer with GSelector on it
- Multiple schedules for different stations
- Can easily see when the station is scheduled, and what is missing from the log – very helpful when programs are delayed from suppliers.
- Can schedule music and programming separately, or Ids, or links etc.
Advantages of SPL over Zetta
- Smaller program size
- Cheaper to purchase and on-going maintenance
- Buy out licence
- Less resources required to run it
- DSP Plugin effects built in for audio sound
- Streaming Module is included
- One small database
- Simple Audio Metadata/playlist history is stored in files
- Lower minimum hardware requirements
- Less computers required to run it
- Can run on Linux or Mac (through Wine)
- Easy to find audio, based on it’s Windows File system architecture.
- Scheduling of programs can be potentially quicker, (but can easily be broken if a reschedule is required)
These are just the things I can think of, but I know there are plenty more differences, and similarities.
Both systems share many things in common, of which many are standard, such as Live assist, Automation, GPIO etc.
I made a comparison a few years ago here:
If you really want to know how good Zetta is, and see it fly from a guy who uses it daily at a commercial station, this video is a must see. The things on this video that are done, can not be done in SPL on the fly like this.
