Impulses
...ng care of this, and before I
bother implimenting something I'd like to make sure that no one has gone
down this path before:
Roughtly vorbis currently does:
input wave -> MDCT -> LPC -> LSP -> quant -> ------------------>output
\->delpc->error->quant -^
What do you think of this:
input wav -> DWT -> sum non-impuse factors -> iDWT -> MDCT ... (like above)
\
-> -> sum impulse factors -> iDWT -> LPC -> LSP -> quant
i.e. use a wavelet transform to seperate out impuls...
