Quad optical audio track S8 projector

[Bill Hauss]

Just came into possession of a Japanese S8 release that has 4 optical audio tracks and I want a projector that I can use to record the tracks.
Thanks in advance

I am curios to know what do you mean has 4 optical audio track. AFAIK the S8 film can only have max 2 audio track, left and right. Could you elaborate please.

4x Optical tracks!? I’ve only ever seen quad-bilateral (mono) optical on 16mm and 35mm optical prints to date!

DIY Optical sound recording isn’t a thing for the domestic market!

I think you’d best post some images of exactly what you’ve acquired for further inspection by us seasoned members to comment upon, and hopefully help you.

Best

Dunno if they're all mono but there are definitely 4 tracks...
Also came which a cassette which I digitized and posted on Internet Archive

Bill, that is a known format for optical tracks.

I did not find a sample on 8 or S8 film. So you are looking for a projector that will play this sound track?

There is a discussion of optical sound on our old forum:

Ideally
I can use the cassette audio recording to screen it for now tho.

Very interesting! I've seen a Super 8mm two track optical sound print with the same audio configuration as main/balance mag stripe tracks. I haven't yet come across the projector that can play back the dual format.
