I wonder if I'm correctly understanding the below terms.
- 
Control object : object that has control inlets and outlets only. (e.g. spigot, swap, pack) 
- 
Audio object: object that has one or more signal inlets and outlets. (e.g. phasor~, vcf~, dac~) 
Am I correct or would you call them in a different way? (e.g. Signal object)
