[13:42] <@atomnuker> well, AAC just requires the random numbers to be only somewhat random
[13:43] <@atomnuker> you could probably replace the random numbers with just a static table of somewhat random numbers
[13:43] <@atomnuker> and that probably won't really change much in terms of the output quality
[13:43] <@atomnuker> though an integer RNG might be useful for some things I have in mind
[13:44] <@Daemon404> we do have one. but it is not 64bit
[13:44] <@atomnuker> yeah, a 32 bit one would be enough
