Theoretical Question : Sampled Sound

[+Muddyfunster]

Would it be possible to play a sample sound on the 7800 via stock hardware, or via Pokey/XM ?

 

I'm thinking just 1 or 2 simple short sounds.

 

Would it be too processor intensive?

Possible? Yes...stock hardware...

 

Soft Cell - Tainted Love (Music Demo) (20140311).a78

 

The above is 512K and max for both animation is concerned as well as processor utilization. 

 

However, for short and brief samples, we have the examples in homebrews such as Astro Blaster and Frenzy/Berzerk. 

 

Astro Blaster features a flashing title screen while playing back the voice sample statement: "Fighter pilots needed in sector wars...Play Astro Blaster."  In Frenzy/Berzerk, all the animation freezes anytime the various voice sample clips play.

 

It is very processor intensive, and I wouldn't expect much else (if anything) to be happening while the sample is playing.

Thanks Trebor !

If whatever cartridge or expansion hardware you're using has a timer connected to /IRQ it'll be way easier to play the samples asynchronously compared to the stock hardware. No idea what the XM supports, but it was mentioned as a feature in Dragonfly.

Dragonfly has the ability to use interrupts from Pokey or YM2151, this is enabled in the Cartridge Menu. Is that enough?

Thanks guys,

 

I was taking a break from EXO the other night and I was looking at a project that specifically has an iconic death SFX and I wanted to know if it could be done on the 7800. I'm not the most clued up person when it comes to SFX and Music. It seems that it could be done  going to park it in the "interesting projects box" for now and maybe I'll revisit that another time, once I've finished EXO and Danger Zone.
