16mm sound formats

• mono - various types (mauer, single track, etc) (stereo was developed in the 1990s and some Eastman projectors have readers for this but no prints were made)
• silent (double perf vs. single perf)
• sound from external sources (digital file, cassette tape, radio, etc.)
• mag stripe (rare for standard projection settings but comes up with home movies and artifacts like Scopitones)
• production elements you may run into (e.g. fullcoat)
• DTS exists in very rare, semi-experimental cases, but this is not something you will run into in an ordinary projection setting.
