Feature Request: Additional Sound controls

Panzer88 · Post by **Panzer88** » Mon Oct 15, 2007 11:27 pm

just like their are varies video filters, how about we have a treble/bass control and maybe other sound enhancement/filtration options/controls.

just an idea.

EDIT: also, would there be any advantage to allowing higher sampling rates as Gens32 does? (e.g. instead of maxing out at 44100 their's goes up to 192000, is this because of sound stuff with the Sega CD or 32X or could this benefit ZSNES too?)

There's no advantage of anything higher than 44100 in ZSNES. We had this discussion many years ago and it turned into comedy club.

Fixed, I guess.

so do they do it because it makes a diff with genesis+Sega CD+32X? (I'm assuming)

not pushing the issue, just solving the mystery.

SEGA used FM synthesis hardware, which afaik can be scaled up to use higher frequencies. Sample-based audio can't be improved like that.

Think of it like bitmaps and polygons. Bitmaps (i.e. samples) have a fixed quality, and filters can only try to increase the quality. Polygons (FM waves) can be scaled with the output device's capabilities, i.e. higher resolutions can reduce the jaggies.

A comedy club hosted none other than Tedius Zanarukando and his doomed quest for 192000 Hz. He did not pass GO.

Plus, he was a friggin' mormon or something. That alone makes people keep their distance.

thanks, I guess the genesis had a few (totally useless at the time) aces up it's sleeve.

multiples of 32000 could be interpolated maybe so if you get 64000 or 96000 or 128000 you can get maybe somewhat higher quality. Although, sound hardware probably does that itself or in drivers at least.

Regarding frequency, the ONLY good frequency is 32000 Hz or the sound effects in Star Fox will not be right.
About sound controls like treble, bass, etc. That will be when Nach finishes rewriting the sound engine, IF you are lucky.

About things like treble, bass control... shouldn't people be bothering their sound card maker for things like that instead of each and every individual program?

And the OS should support save stating of every program too, but they normally don't

I knew this was going to be brought up, and I agree, except not everyone's sound system can change such things easily, I mean we have color adjustments etc. in the NTSC filter so I thought some audio sound options wouldn't be a completely bad idea.

of course it's all up to the ZSNES devs.

What, you've never used Nach's Tool for SNES Copiers?

Oh for a moment there, I thought someone joined Nach's Technical School for Crazies.

well that was a glorious type, *sigh* oh well.
