SNES Audio Unit As Stand-Alone Player 168

Posted by timothy from the you-must-stand-alone dept.
An anonymous reader writes "Raphael Assénat successfully turned the SNES' audio processing unit into a stand alone unit which can be controlled through a parallel port, allowing people to play SNES music separate from games and the SNES' main unit. Elsewhere there is also a tutorial about adding S/PDIF digital sound output to the SNES."

    I love SNES music.. I've got a few OSTs (original soundtracks) dumped to mp3, but they just don't sound the same as the original. Zophar.net has a good archive of SPCs and links to plugins for winamp, etc. Very cool stuff. Also, Skytopia [skytopia.com] has a lot of interesting and relevant info.

The Alpha-II player is really hard to tell from actual SNES hardware in when it's told to emulate it as accurately as possible. However also fun is it can get much better sound. The orignal SNES mixed at 32khz 16-bit with Gaussian sample interpolation, which leads to a fair amount of error, even with the low quality samples it used.

    Any music of any SNES game has been available for many years with the .spc file format. The audio files sound exactly as the music would sound on the SNES console.
    A really large .spc database can be found here: http://www.snesmusic.org/spcsets/#so [snesmusic.org]
    • I wouldn't say "exactly". None of the emulators manage to emulate the SPC perfectly, and the music playing apps are just emulators with everything but basic CPU emulation and sound core emulation ripped out. We've seen it before with the SID chip, why shouldn't it happen again with the SPC?

    i think that's very cool. i love to see new efforts being drawn on retro hardware.

    but i do wonder why one would bother building a parallel port unit to play the music when there are software emulators doing that work for us already?
    if it were truly *standalone*, then it would be a fun, useful way to incorporate it into music projects or just have fun - but as it's tied to the computer already, why not just use the software?
    • I wish i had a mod point for you. You point out what screamed at me when I first read this. I guess it's just one of those "Well, I just wanted to see if I could do it." projects. Emulating would have been alot simpler but no where near as cool.
    • I am very fond of the SNES sound processor. The SPC-700 is an amazing little machine that still makes me smile even today. But there are actually some software engines that can enhance the original SPC code.

    Yeah, I know why bother? But most of the time when new gaming hardware comes out it is only used to a fraction of its full potential before the next generation arrives. So part of me really thinks it's cool to squeeze out some of that perhaps untapped potential like this. Maybe Tree Wave [treewave.com] will play something with this.

    For things like the commodore audio chip you can't get exactly the same sounds without the real hardware. But for SNES I think that zsnes + roms + alsa does a pretty faithful rendition of the sound. And if I fiddle with the sound options you could argue that however unfaithful the sound becomes, it is actually superior in quality to that of just an SNES.

    That's one thing the SNES did have over the Genesis. The sound quality was vastly superior. I remember the "echoy" cave noises in super mario world, that was something else.

      • I *almost* bought a SidStation until I found out how damn difficult it was to fool around with. Also, I was doing my best to sell all my hardware, so I bought QuadraSID, a virtual SID synth VSTi plugin. It gives you the equivalent of Four SID chips or something close to that.

      • Well that's because the SNES chip was just a simple sampler. Samplers are still in heavy use, in fact there's a huge market in samples these days and the quality is stunning in many cases. Check out the demos for SO platinum form soundsonline.com and keep in mind it's all synthesized.

        So the SNES's chip doesn't hold any special intrest, other than recreating old music, since there are new samplers that are much better. I mean why would I want to be limited to a tiny amount of compressed 8-bit samples when K
      • even the dookie sound chip in the MD/Genesis could be refabbed with an interface that liberates it and affords it a special niche all its own.

        Perhaps not; wasn't the sound on the Genesis/Megadrive handled by a separate 6502 8-bit CPU acting as a copro to the main 68000 CPU, rather than custom hardware?

        Thinking about it, did that 6502 run some sort of audio soft synthesis code, or was it completly up to the game designers to program it to generate sounds?

    • The Commodore SID is a waveform synthesizer. The SNES sound chip is a sampler. They are two different classes of synthesizers. The SNES sound chip has the opportunity to sound much more realistic given good samples. But this doesn't mean it is "better" in any way than SID - they are incomparable because they are fundamentally different. For example, what if I don't like sounds that sound like real instruments?

    The SidStation is essentially a MIDI synth expander that uses the SID chip as it's main sound source. It'd be interesting to do the same kind of thing with a SNES sound source, although from memory, it wasn't a sound chip worthy of any merit [sidstation.com].

  • The one thing I really wish ZSNES/Snes9X had is the ability to isolate individual sound channels during sound playback. I remember that Nesticle used to have the ability to turn off and on the various NES sound channels (i.e., triangle wave, square wave, etc.). That was really useful for sampling e.g., just the bass line of a particular song. Is there an SNES emulator that does this? Or better yet, is there an SPC player that does this?
