TODO

list of things to do...

libupse (emulation core):
   - seperate public API into their own files
   - lots of stuff is in various static variables littered around
     the source, turn that into a struct upse_state_t so that multiple
     upse sessions can run at once
   - implement ADSR filter dithering for 44100->22050kHZ transcoding,
     interpolation SUCKS here -- many bits are simply lost
   - make it possible to trap CPU and SPU instructions at runtime,
     and expose public APIs for doing so
   - implement config parser, and support for .upserc
   - check my math on the differential interpolation phase (is it
     different on PSone than it is on PS2/PSX? some say PSone uses
     a logarhythmic method...)
   - find out why crash bandicoot sets fail
   - improve tracing
   - PSone MIDI extensions
   - lots of dead code: find and kill
   - document the public API (doxygen)
   - gaussian curve used to start post-mix interpolation is probably
     wrong

wishlist:
   - code-level debugger?
   - PSF autoripping tool
   - implement missing PS2 bits from PCSX2 (lu_zero says he is possibly
     interested in this) -- but this isn't so big as most PS2 games use
     AAC or ATRAC files -- only like 20 games actually use mods
   - winamp and/or foobar2000 plugins?

upse123:
   - handle audio system errors better (right now we lock up solid)

upse-audacious:
   - configuration dialog

upse-xmms2:
   - implement? is it worth it?

gst-upse:
   - implement so that gst users get quality PSF playback!
     + pick deadchip's brain on how best to handle upse's callback design
