The SPC700 DSP Pipeline Explained - SPC700 Series pt. 4

What exactly does the SPC700's digital signal processor have to do to produce sounds and music? It's all explained right here.

I love seeing how similar SNES DSP and PS1 SPU are - they basically increased sampling rate and number of registers, everything else (including register names and functions) are a exact match.
Love your videos, helped me understanding how internally samples are crafted and fixed few bugs in my PS1 emulator.

I hope we get some proper audio examples in future episodes, I can never follow sound stuff without them too well

This is an excellent series - I hope we can see a part 5 at some point?

This is so thorough and beautifully edited. Thank you so much! I can't wait for the envelope video, I'm programming an ADSR editor for SPC file hacking and composition.

This is all pretty abstract – I wish you could have given examples of what messing with these values actually sounds like

[BadPrenup]

Hell yeah, another extensive look into a retro technology that, even when broken down as well as it is in these videos, is way beyond my understanding.

Keep up the good work RGME ❤️

I read that as scp700 and assumed all Nintendo's were haunted

[PaulFisher]

This is so cool! I had no idea the SNES had such a complex and powerful audio pipeline—this explains a lot about how sound designers and demosceners are able to coax all that cool stuff out of it. Looking forward to watching some samples make the journey!

the SPC is my favorite sound chip of all time and I deeply appreciate you explaining the nuts and bolts of how this powerful little chip operates

Did You Know? The design of the PS1's audio subsystem is nearly identical to the Super Nintendo's. The biggest different are the size of the audio sample buffers, RAM, and registers.
As a result (as I've seen in other videos), the Super Nintendo is more than capable of reproducing the sounds and effects of PS1 or PS2 consoles, particularly their start up sounds, just with a lower bitrate that results in them sounding crusty and lo-fi compared to their intended quality on the PS1 or PS2.

Cannot thank you enough for the meticulous and detailed documentation of all this hardware. I know the SNES is pretty much cracked wide open at this point, but the more the merrier.

We should be so lucky to have this level of analysis for all the consoles.

This really shows how ahead of its time the S-SMP system was. Amazing work!

[TeufortHeavy]

I love this channel for some reason, keep up the amazing content!

[Choralone]

I love the deep dive into the SPC700! Even back when the SNES was first released I knew it had a really complex sound system as the sound and especially music of early games like SMW, F-zero, Actraiser & FF2 was so far beyond anything on the NES or even PCs equipped with a FM based sound card like the Adlib. I'm looking forward to future videos in this series!

[SuperSpybob]

I will never understand how these videos can be on such an esoteric topic, yet every time they come up on my feed I can't click fast enough.

[jscruffins]

as a Super Midi Pak user, I cannot express how valuable these videos are! Thank you!

[soviut]

Please, oh please, include audio examples in the next video as switches and values change within this setup.

[JeanQPublique]

Great stuff! I never imaginged getting the chance to understand the SNES hardware like this. Thank you so much :)

[smartperson]

Great video. I appreciate how you used a different X for ENDX vs. VxSCRN and VxP.

[elbiggus]

I'm never going to need to know any of this stuff, a lot of it goes over my head, and as far as I know you could be making it all up, but I'm still really enjoying this series!
