Oscilloscope visualization of "Wake Up" (also known as "Sekence") from the 1992 DOS game "Dune", recorded from a real OPL3. Unfortunately, I am not the one who recorded this, but I forgot who recorded this already since it was years ago since I downloaded this. However, on the comments of the file, it says:
"Recorded from a Cardinal SoundVision OPL3 sound card using a Emotiva UMC-1 (CS42518) as analog to digital converter and digital coaxial out to a Sound Blaster X-FI Elite Pro (ASIO) with no volume attenuation or post processing."
The audio is recorded from hardware, but the visualization was recorded from vgmplay.
