Regular 8mm movie film was never sold commercially with a sound strip but some people did attach a sound strip themselves. Super 8 film has the option but you had to buy the film with the sound strip on it and you had to have a sound camera and microphone. 16mm had both magnetic and optical. On the order form you can let us know if you think your film has sound on it. It does take extra effort to capture the sound and incorporate it into the requested formats. So, we do charge a little more for sound film.
We can not capture any digital audio like Dolby Digital or Sony Dynamic Digital Sound.
The above picture is just an example. 16mm sound film came in many different varieties. 16mm film with optical sound will have sprocket holes on 1 side. The other side will carry the audio track.
There is no sound on Regular 8 film. At least it wasn't produced that way. There were some people that put a magnetic sound strip on 8mm film themselves. There was also some test 8mm film with sound that Kodak used to prepare for Super 8 film.
Super 8 sound could be recorded with a microphone during filming or could also be recorded using a projector when the film played. The quality of the sound varied widely.
Boulder Fun Facts: Congress and in 1871 Boulder (then known as Boulder City) was incorporated as a city. Five years later the University of Colorado at Boulder opened and in that same year (1876) Colorado achieved its statehood. Through the early part of the 20th century, mining and tourism were two of the city's principal industries. Later years saw a different kind of industry with the arrival of the National Bureau of Standards (which today is the National Institute of Standards and Technology, home of the atomic clock) and the National Center for Atmospheric Research.
Colorado Fun Facts: First explored by Europeans in the late 1500s (the Spanish referred to the region as “Colorado” for its red-colored earth), the area was ceded to the United States in 1848 with the Treaty of Guadalupe Hidalgo that ended the Mexican-American War (1846-48). In 1858, the discovery of gold in Colorado attracted new settlers. During the Plains Indian Wars (1860s-80s), Colorado’s wild frontier was the scene of intense fighting between Native Americans and white settlers. In the 21st century, Colorado continues to rely on its natural resources as well as agriculture and tourism to sustain its economy.
