If you think about it for a minute you'll see there are some real issues when it comes to converting waves back into color vector art.
The output a any DAC is more or less a set of analog signals. If you record that with an ADAT or similar multi track recorder, that recorder has no connection what so ever to the DAC clock. The recorder itself will have it's own clock, probably at a fixed rate of 48KHz (maybe 96KHz). So you will end up with vector data that is sampled at 48KHz. That's 48000 samples or points per second; regardless of the laser DAC clock rate.
This might be the reason for this comment:
That's not LB adding any extra vertices. It's the ADAT clock.
Another issue is the time delay between the scanner signals and the color signals. The way you deal with this is by time shifting samples between the channels. So your smallest quantum of time to use as an adjustment is one sample or 1/48th of a second.
Then there is the issue of framing. That is the most difficult thing to deal with and in many cases there isn't anything you can do except pick some arbitrary number and split up the wave data into that many samples per frame.
I spent some time looking for a way to identify a big blank spot at the end of each frame, but that technique is easily confused with frames that have lots of blank in them. And not all laser DACs / software use the idea of a time synch blank spot at the end of every frame.
LaserBoy has a black level setting that lets you specify a number that is close enough to black (0.00 on the red green and blue) to be called black, therefore blank.
It also lets you set the number of samples to shift in time to align the colors to the scanners per channel.
You can also set the number of samples you want in each frame.
You can import waves into the memory model as a frame set or you can just display the wave on the screen either in real time or as fast as your computer can render it.
Another important thing to note is that you have no way to know if the original ADAT recording was made at full scale. As long as it plays back the same voltages that it recorded, it works as a laser show recorder. But the recording might not go to full scale. So it is a good idea to open your ADAT waves in Audacity and normalize the channels. It's best to select both scanner signals together and normalize them to zero dB. Then you can assume that at least at some point, each one of the color signals will hit full swing. So you can normalize each one of them separately to zero dB. That way, when you import them to LB you'll get a full sized image with the brightest possible colors.
If anyone knows exactly where DZ's abstract recordings are please post a link.
