- ** PLEASE, WATCH IN HIGH QUALITY FOR PROPER AUDIO! **
So, I decided to take a look at all the separate channels of some chiptune music at once. Thought it might look cool, since those waveforms are usually so pretty.
I figured BeWu from Grayscale Project wasn't getting enough love on my channel, so I'll upload some of his music too.
This is a video made with a complete rewrite of my original Python script, which I'll be releasing to the public soon after a few more tweaks to the algorithm.
I finally got around to implementing my "TimbreCapture" algorithm, which finds the exact waveform shape being repeated for a note (the timbre's minimum waveform) and consistently centers it on screen. This way we can always see the exact shape of the wave being played at any given moment and how it changes.
It's working well so far (misses a few weirder waveforms), but I still need to add a couple more features to it. Stay tuned for the source code soon.
Oh, and there's more! I'm also going to be releasing the source code for my tool to convert POKEY dumps to MIDI files. These will require a modified version of asapscan from the ASAP library.

The Grayscale Project is an awesome Atari 8-bit music collaboration from Poland. Members are:
Grzegorz Kwiatek (Greg), Łukasz Sychowicz (X-Ray) and Bartek Wąsiel (BeWu).

You can find their work, along with tons of other great Atari music, on the Atari SAP Music Archive (ASMA) at:

I'm not even a POKEY fan, but this is stellar, epecially composition-wise
Oh hi Midi :3
Hi :3
POWER TO THE POKEY ! Wonderful song... very perky and upbeat, feels like digital happiness. :-)
This is one of my favorite Atari SAP songs ever!
Thank you!
instant love
That spiral piano is being made into a prototype within the next few weeks by myself and a friend. I thought I was the first one to think of it. Haha.. nothing original under the sun, I guess. Check out our first prototype.. it’s essentially a music theory calculator. Many more inventions to come!!
I say, this is a classic type of dubstep. Well done.
THX. 💻📺
I Love the beat & I can get enough wave forms.
you can?
will there be any chance on releasing your oscilloscope program?
I'm seconding the question //nevermind i just read the whole description, staying tuned then
It's been two years, it is less likely to be released to public. Maybe 2023, or 2024.
1ucasvb is still active on Twitter.
nice track
awesome
Hey u channel is amazing. I loved how u explore the waveforms n harmonics of sound signal, no many people know this in detail. Are you a musician or an engineer?
Hey, thanks! I'm neither. I'm a physicist.
Which Oscillator Program are You using?
It's his own program. RushJet1 wrote SidWiz 2 which is similar: mega.nz/#!jgsCDbYa!b4S9HAJhmmnxuo0ax4_GnqIqRH8FYVGHWV8z0YKqJSI
This is what the Atari 7800 could have potentially sounded like if Pokey was used as the audio chip?
Technically this appears to be a dual pokey arrangement, which only modded systems had.
Pokey is alright, but you have to devote a LOT of CPU time to do anything non-trivial.
Would have worked wonders in designs that could afford a dedicated audio CPU I guess.
But anything that could do that would likely have access to audio hardware way more advanced than something like Pokey...
@@KuraIthys you need to watch Jay Miner's talks. There is no need of " a lot of CPU time" even with the Pokey's High Pass Filter feature. The idea of a chip being able to fetch and reproduce samples was realized by two channels (pokey) and was applied in full scale on Paula(Amiga). Now the music with or without a second pokey is reproduced just fine. The only thing that it's missing is the stereo effect. I have machines with and without a second pokey and the tune is the same on both configs. There are creators of demos (check Reharden, Gene lamers etc) who use high pass and bass routines which are dirty cheap in CPU time ...and this is why they are able to reproduce music and move graphics at the same time.
chlopie, wracaj na yt
Do some Gameboy visualizations!!!!!!!!
I'm not very familiar with GameBoy music. I'm open to suggestions!
Why? What about C64?
I dunno, I guess I never had much contact with GameBoy music. I never owned a GameBoy, nor an Atari computer or C64, but I never got around listening to GameBoy stuff. I'll check it out and see what cool stuff I'll find. :)
As for C64, back when I started making these videos there wasn't a nice tool to extract individual channels of SID music. There are now, and I plan on doing a lot of C64 music soon-ish. But I want to figure out the new algorithm for capturing timbres in place, since that's not a trivial problem for more complicated waves. (Atari POKEY only does squares, so it's easy.)
There is another guy on CZcams, RushJet1, who copied the style of my videos (not complaining, I don't mind) and wrote his own tool, SidWiz. A few people (Highway Guy and Rolf R Bakke) are using that tool now to make C64 and GameBoy Color videos, and you can find them around if you search.
I don't really like the way they're doing it, though, there's no consistency and aesthetics to it. But at least more chiptune is getting out there and being appreciated, so everybody wins. :)
I'll be releasing my own code soon.
