When people post videos of old games with PC Speaker music the sound is usually coming directly from emulation and sounds very harsh and garish.
This is actually different from how it used to be as this process ignores the environment the sound came from: A magnetically driven speaker internally attached to the metal case, creating a resonance that gave the pure 'beep' sounds more body and texture.
If you'd like to hear what it actually sounded like, this video got it right: https://www.youtube.com/watch?v=tUy1MEpqbvk
I thought that the old games don't sound as good as I remember them because nostalgia. I hadn't really considered it past that
@polychrome I forget exactly, but I'm pretty sure that there's some PC Speaker emulation, either software or hardware, out there that I read about a month ago
(use google translate from finnish)
@polychrome I actually hacked on a SID emulator that would load the measured impulse response of a real speaker to emulate the sound as faithfully as possible. Yet another project I never finished :V
@lachs0r neat!! maybe you'll finish it one day?
Is "impulse response" the technical term for what I was referring to?
@polychrome Maybe one day. Or I might contribute to existing emulators.
The impulse response is a characteristic of an audio reproducttion system. Everything between the DAC and the listener contributes to it. If the response of a system is known, it can be used to convolve a signal to reproduce its sound.
A different use case for this is digital room correction.
If you use Linux, you can use JACK+jconvolver to process any software’s audio signal in real time through such a filter.
@polychrome So yeah, it is the term for what you were referring to.
Also, I don’t know how all the mathy bits behind this actually work (because I don’t need to). But I got a measurement microphone for room correction. I don’t have an actual C64 or old 8086 machine with a nice speaker, but I could try measuring a GameBoy or something. Because GB emulators don’t sound like they’re supposed to either.
@lachs0r the good news are that your PC motherboard still supports the PC speaker pin outs and the speaker itself was just a bog standard magnetically driven speaker (unlike the crap piezos that replaced it in the early 00's) latched with it's face to the inner wall of the chassis so any non-piezo PC would do, or you could possibly hook one up to practically any box yourself.
The only issue with modern PCs is that cases are designed to keep things very quiet which might muffle the speaker.
