KFFI Presents... Echo Synthesis?

Direct from Kung Fu Furby Industries, it's a demonstration of a SPC capability that... well, the browser's SPC player will not replicate properly. It's a technique that manipulates the FIR coefficients as well as the EFB DSP register to produce sounds you wouldn't expect the echo buffer to be capable of producing. In some ways, it almost feels like it could be used to try to create some discrete-like audio (albeit not as analog)! The biggest requirement, though, is that it needs a seed: that is, either a sound, or what I just simply do is write bytes directly to the buffer. No voices required, either.

The Power of the Echo Winds of Creation await...
Download SPC File
Download BPS Version (use with vanilla SMW, though this isn't an actual ROM hack)
Download MP3 Render

To be honest, I'm as music illiterate as it gets, so I have no idea what any of those words mean. Also, I'm not sure if the SPC player in VLC plays the file correctly, because I'm getting a two minute audio track that consists of mostly silence and only like two audible segments. Is that what's supposed to happen? If not, then maybe converting the SPC to an MP3 file for preview purposes would be a good idea. Or at least letting us know which player can play it correctly? (Is it just SPC700 Player?).

The few audible bits I did hear were certainly interesting, though. These gave me some 70s arcade game vibes, and I certainly didn't know you could produce sound like that on the SNES.

Feel free to visit my website/blog - it's updated rarely, but it looks pretty cool!

Nope. It's supposed to be more audible than that, so done and done: I created an MP3 render. I also created a BPS version to patch on top of a vanilla Super Mario World ROM (since I can just simply compile a ROM of the SPC) that will also play the sound in question.

Aha, now we're talking! What my brain hears is a combination of a vacuum cleaner, a siren, wind and then towards the end arcadey sound effects. Definitely sounds impressively rich for something coming from the SNES!
