| 00:10 | < Yossarian> | More source but it's written in VB so I'm having a hard time understanding. |
| 00:10 | <&McMartin> | The important parts should just be math :/ |
| 00:13 | < Yossarian> | I'm sucking at that, with the bits and the addresses |
| 00:14 | < Yossarian> | i wonder how long a sample can be |
| 00:26 | < Yossarian> | Damn, I don't understand this code at all. |
| 00:28 | <&McMartin> | https://wiki.superfamicom.org/spc700-reference#toc-46 seems to include a stripped-down incomplete version |
| 00:28 | <&McMartin> | And OK, looking at this it's some kind of thing where each sample is a function of the previous two samples as well as four shifted bits of new data |
| 00:28 | <&McMartin> | And it's 16-bit PCM. |
| 00:29 | < Yossarian> | I presume on any given file that 50% of it put into RAM or if that includes the registers in vspcplay |
| 00:30 | < Yossarian> | the other 50% are samples, be nice to get some. 16-bit PCM, eh? |
| 00:30 | <&McMartin> | 16-PCM is what it decodes to |
| 00:31 | <&McMartin> | The "BRR" format seems to be what stuff actually is that the chip eats |
| 00:34 | < Yossarian> | I'm not leet enough (yet) |
| 00:37 | < Yossarian> | Maybe I can modify the tool a little bit. |
| 00:58 | < Yossarian> | I found another program and I can see the instruments but it doesn't provide a way to reverse engineer .spc file but you can export to it |
| 01:32 | <@celmin|away> | BTW, are there audio formats that aren't PCM? |
