Variable Documentation

gSynthesisReverbs

struct SynthesisReverb gSynthesisReverbs[4]

sAudioSynthesisPad

u8 sAudioSynthesisPad[0x10]

synthesisAudioString0

char synthesisAudioString0[] = "Terminate-Canceled Channel %d,Phase %d\n"

Given that (almost) all of these are format strings, it is highly likely that they are meant to be used in some sort of printf variant. But I don't care to try and figure out which function gets which string(s) So I've place them all here instead.

synthesisAudioString1

char synthesisAudioString1[] = "Copy %d\n"

synthesisAudioString2

char synthesisAudioString2[] = "%d->%d\n"

synthesisAudioString3

char synthesisAudioString3[] = "pitch %x: delaybytes %d : olddelay %d\n"

synthesisAudioString4

char synthesisAudioString4[] = "cont %x: delaybytes %d : olddelay %d\n"
