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.
Even though Super 8 film was sold in two versions, sound and silent, most Super 8 film is silent. Only about 5% of all Super 8 movie film has sound on it.
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.
