Finally, after some hours looking in hex editor, googling and d/l torrents, i can all types *at3 files, without psp.
Whats different between AT3+ BGM (can be decoded by sonicstage +himd renderer) and voices? Voices encoded in mono
.
Just open any at3+ voice in hex and look on offset 3Eh. You see 24h
Now, look in this copypaste from Symphonic:
After some googling, i found another codec: i\o plugin in Sound Forge pro 10.0
. But it can't support wav container. Only *.oma. Some more googling to find OMA specs, and i found THIS
After splitting oma header+ offset("data"+4) Sound Fogre can import any atrac3+ sound from psp.
Now, time to write tools (need separate "70 02"/"FF FF" sounds, and remove wav headers in output wav's) and batch converting.
Ухх, отпустило...

Quote: /* AL = Advanced LosslessI suspect that the sony's players do not support monophonic atrak3 +, and in the Sonic Stage's codec support of "mono" is also removed.
