Real-time Audio Effects on the SNES

[@dinospumonii]

These features were actually used extensively throughout the Donkey Kong Country 2 sound track :) Thanks for sharing this!

[@kromanaut]

WOW! This is a pretty big deal, opening up entirely new realms of sonic possibilities from the SNES sound chip! Thanks for your work on this.

[@supermidipak]

Thank you for watching!

[@voilabolognessich423]

Amazing work! Thank you!

[@TronDawg]

Thank you so much for the continued support and expansion. Wow, just Wow 🌊✨🌊

That's awesome. And thanks for the z-transform brush up. Very well explained. Personally I would change the frequency scale in the filter designer to logarithmic, so it makes more sense in an audio context.

[@supermidipak]

Yeah I've been thinking of adding some toggles to change the units of the graph. Different scales are better under different circumstances. For instance, I originally implemented group delay for the phase response display but group delay isn't always the most relevant way to understand the response. Thank you for the kind words!

[@corri303]

@@supermidipak Oh right , speaking of delay, observing comb filter effects caused by delay does look better on a linear scale. So a toggle would be the perfect choice.

Surprised this is the first time seeing this channel. The visual plotting of the z-values relating to the tf was really nice ty!

Thank you for Our huge efforts by making this amazing content about the midi pak! I'd love to finally start making music with it but unfortunately I've lost mine before I could even start making music with my Super midi pak 😞

[@supermidipak]

I'm sure it'll turn up!

[@capnzilog]

Brilliant, good stuff!

Is it possible to use this to find cool-sounding FIR parameters for use in homebrew projects or songs written for sound drivers like AddMusicK, or does it only work on a physical Super MIDI Pak?

[@supermidipak]

Out of the box it works with Super MIDI Pak but you can use these settings in any SNES homebrew project or with other tools. You can do it by pen and paper or you can automate it by presenting a MIDI device to the web app and capturing the FIR register output.

[@famitory]

is it possible with the SNES's FIR network to create resonant highpass/lowpass filters? my assumption based on not being able to precisely control the poles would be no but i'm not really familar with the math

[@supermidipak]

You can but the shapes of filters that you can produce are limited. I'm working on a pole-based filter generator and my next video is going to be about that!
