Good methodology compress via MP2 audio files? (except Ocarina, still very slow.)
My horrible methods:
Code:
unpackmp2+srep:m3f:a0:l32+msc:raw=1:tak=9+delta+dlz
DLZ replaced via NZ/LOLZ its probably better. (and/or without delta filtering.) Tested one 192MBs MP2 file packed to 152MBs size. Final ratio minmally smaller than 80%*
DLZ replaced to Ocarina probably the best and slooow results. This MSC will found ~35-36 million bytes raw audio from processing and packed via TAK. Before used or not SREP precompression.
*Three step compression: 201 348 000 -> 335 766 244 -> 314 530 933 -> 159 583 312 byte
DLZ replaced to MPZX (64MB block size) results: 173 752 545 byte
NanoZip0.09/cO/768m, before not used delta filtering: 152 764 729 byte (~76% final ratio. Typically MJPG/MP3 recompression ratio.)
