  • A user named Intron on my Discord server mentioned to me that I should try using dithering while down-sampling the sound effect to make it sound better. I did just that and it sounds way better!

    • Yes! Dithering makes it better! The 1-bit sample must also have been dithered as a 1-bit sample sounds HORRIBLE otherwise. :) In fact, i was lightly shocked when i heard the quality and saw the waveform. Most examples of 1-bit sounds on classic machines is way worse. Also, the original high quality sample is certainly NOT 32 bits. :) You can't actually sensibly record such a large dynamic range due to acoustic and electrical noise. And since this sound was produced in the 90's i'm certain its bit depth is 16 bits at most. You may have stored it (basically for no good reason) as a 32 bit sample. Maybe you naively decoded it from an MP3 or such. But 32 bits is an incredible amount of overkill for sampling audio. 32 bits provide a dynamic range of over 192dB. That's waaaay bigger than the dynamic range of human hearing. Normal audio equipment seldomly provides more than about 100dB of dynamic range. If you have a very good (pro) system then it may go down to 120dB. This is still less dynamic range than 24 bits (which is the standard in pro converters) provides. That can code about 144dB worth of dynamic range. So all in all, imagine the softest sound a CD can produce, basically the LSB of a 16 bit sample. Now imagine that that single bit is basically a whole full 16 bit worth of signal. That's what 32 bits basically gives you. (Yo dawg, i herd you like CD so i put a CD in your CD so you can 16 bit while you 16 bit...) It has the effect of coding a whole CD worth of signal at the amplitude of just the lowest bit. But the thing is that under any sensible listening situations you will not hear this bit. You would have to pump up the sound so loud in volume (to hear the bottom of that 32 bit scale) that your ears would be instantly -obliterated- (in fact, probably your face too) if any full scale signal came along. So it doesn't make any sense at all to use 32 bit samples (well, there are exceptions when GENERATING sound waves, like in a digital synthesizer. But that is different.). And since the sound is sourced with a microphone from the real world you can be sure that it's going to be all noise below, say 80dB anyway (talking about a good microphone). Studio's these usually work at 24 bits bitdepth and that allows them to basically crank up the volume on certain soft sounds without losing quality. It allows for a margin of error and it's enough for pro's. Anyway, i'm blabbing too much. Hope i explained this properly and you learned something :)

    • Better than dithering would be to apply a lowpass filter to the audio with a cutoff of something like 1 kHz, then downsample to nyquist. You don't need a very high sample rate to make a good sounding human voice, but you definitely want more than 1 bit per sample if you can get it.

    • I used to have a gameboy demoscene rom that played an entire song by the punk band "The Exploited" with an animation of their logo over the top of it on Gameboy color hardware. I had another that played an FMV of the trailer for The Matrix.

  • I don't know a lot about the technical details, but there is a video about tasbot playing portals still alive on a Gameboy Color by feeding the RAM with the (compressed) sound Data just using user input (about 1000 inputs per second). They did use some compression techniques to improve the quality even more than this one, even though I do believe that the data would exceed the ROM by a large amount.

Then LEARNING how the gameboy CPU actually controls these sounds in one of my favorite handheld video games ever made... Its just a CAKE. A beautiful, delicious, almond extract icing, tons of fondant, perfect decoration, nice thick layers... holy FUCK ive never been more happy with a videos construction and content like i am right now. EXCELLENT work sir.

  • What sounds like a good general video idea is to take a concept of a game, restrict ourselves to a set amount of processing power, and see what optimization/fancy code we can come up with to achieve a game/function. A good example of this is a game "Micro Mages" where the developers managed to fit a multiplayer game on an 8bit NES game.

  • Little Nicky and Cannon Fodder probably do the circular buffer method, using a low sample rate by using a low wave pitch, and then making extremely slight pauses to update the waveform. When this is done, a minor buzzing sound is created, which is definitely the case with Little Nicky and Cannon Fodder.
