Trying to achieve 'perfect' pc speaker sound

Hi everyone. 

I was looking around for pc speaker audio samples in preperation for this jam and stumbled across this video. It's about the differences between the pc speaker emulation in DOSBOX and the real thing.

The cool part is that the real pc speaker has this robotic quality that I had completely forgotten about after years of emulation, but it instantly brought back a feeling of playing games on old IBM hardware.

Listen to the difference between DOSBOX at 2:39   - And   6:11

(The latter is actually simulated as well, but much closer to the sound from those classic ID games I think)

Anyway of course I'm trying to recreate that sound for my CGA jam game.
I'm using VST's. Does anyone here know of a way to recreate that robotic sound with music software. I tried throwing LFO's and FM modulation at a sqare wave, but I can't seem to get very close.

Might be a long shot, but it's worth a shot :)


famitracker had a PC speaker instrument set in a forum topic called "PC Speaker Challenge". Tried and tested, have fun

Thanks a lot! It's not really the sound I had in my head, but it's still great.

Really cool post. Thanks for sharing this mate!
