I enjoyed listening to some of those. I always liked PC speakers and FM synths. Your channel reminded me of another channel I was looking at a while back: https://www.youtube.com/channel/UC7wN4_Ba1lTPQsVCID2sF3g
He feeds midi tracks into different synthesizers which can be used for comparison.

Which build of DOSBox are you using to capture PC Speaker audio? The "official" version 0.74 has incomplete emulation, leading to many games (especially Apogee titles) sounding wrong. SVN builds like Daum by ykhwong address these issues.

Interesting!
Can somebody share some knowledge how to rip game music in dosbox and upload it to youtube with still picture? 😎

I have modified the official source code of DOSBox and included logging of certain ports related to PC Speaker. Here's the result:

Thanks a lot for your help! I've finally managed to compile 😵 DOSBox and add the logging code. If interested, you can download it here. It requires SDL.dll. It stdout-logs relevant ports 42, 43, and 61 in the format "$42:state=value" | "$43=value" | "$61:oldvalue=newvalue" @PIC_Ticks. I am eventually going to write an application that would convert it to more computer-readable format, maybe the one used in Monotone. 😀

If you run this version with "-noconsole", it will create stdout.txt in the directory with the logging. Then, you can use my tool pcsconv to convert it to a more usable format, mainly DRO for further processing, and WAVE render. It lacks a bit in documentation, so you would probably need to look in the source code for more advanced parameters. For DOSBox output, "pcsconv -in pcs -out wav stdout.txt output.wav -w:v 0.5" converts it to WAVE with 50 % volume. Add "-m" for multiple channels support.
