Need help recording laser images to play back shows

[Illumicon2025]

Hello Everyone,
I was a laserist years ago running shows in planetariums. I got out of the business for a long time, but back into it as a hobby. I use to use FM encoded 8 track tapes to record the images for a show and need to find a way to do something like that but without the limitations of FM. There were 2 audio tracks, 2 flutter tracks, and 2 x and 2 y tracks, no color info. I have Quickshow w/fb3, and a laser radiator, but not confined to Pangolin ecosystem, and trying to get my lsx license fixed. I would like to be able to record 2 audio tracks along with 2-xy images and rgb. I have an adat but they are getting harder to find and really hard to get tapes. Is anyone doing something like this? I like analog images, so the frequency response needs to go from DC and up, and I like to build images up from something simple to more complex as the music builds so live recording is better. Any help would be appreciated and I can elaborate more if needed. Thanks, Fatboy

The Bela low latency audio platform can simultaneously record stereo audio at 44.1kHz and eight ADC channels at 22050Hz, and also simultaneously output stereo audio and eight DAC channels at the same rates.

Great information! Thank you. I am looking into it.

My youtube channel is The Golden Age of Laser Shows. Everything posted there was output from a system I developed using four bela "starter kit" devices and a lot of support from the elders and rock stars of live laser concert history.

The open part of the platform shown in the videos is a c++ file I can offer those new to developing for bela.

This file brings together all the audio and non capacitively coupled AD and DA bela hardware, including file saving and loading, into the same collection of resources that all the stuff seen in the videos uses.

I even have extra boards and docs if you decide you want to build a copy of the hardware part of my four channel system. Very simple stuff involving through hole resistors and socketed quad op amps. I've built two duplicate systems adapted to studio and portable jukebox work.
