Another Mono Atrac3+ Decoder

[freefive]

interesting, tracking down the correct SF was troublesome (9.0e), anyways it can be used to replace the default converter just edit '<jpcsp>\lib\windows-amd64\DecodeAudio.bat'
and change to

Code:

@echo off
set name=%~n1
lib\windows-amd64\atrac3plus2wav.exe %1
rename %1.wav %name%.wav

Although it works and converts mono, I quickly tested Wildarms XF and the voice (mono at3+) has a high pitch noise to it within Jpcsp, stereo files sound/play fine like before, so maybe Jpcsp is trying to play the mono wav in stereo. possibly a fixable jpcsp bug or running the wav through another converter like ffmpeg to convert to stereo.
"44100 Hz, 1 ch, s16le, 705.6 kbit/100.00% (ratio: 88200->88200)"

Hopefully an open source alternative will be available soon.

Yes, I modified the module150/sceAtrac3plus.java

Code:

setAtracOutputChannels(codecType == PSP_MODE_AT_3_PLUS ? atracChannels : 2);
-->
setAtracOutputChannels(2);

And then jpcsp plays the mono wav files will. No high pitch. Tested with
Tales of the World - Radiant Mythology 2 ULJS00175
Tales of the World - Radiant Mythology 3 NPJH50353
Shining Hearts NPJH50342

By the way, my DecodeAudio.bat looks like this:

Code:

@echo off
lib\windows-amd64\atrac3plus2wav.exe %1
move %1.wav %2
IF NOT EXIST "%2" ( lib\windows-amd64\HIMDRender.exe -e -i %1 -o %2 )

because somehow atrac3plus2wav.exe can't convert ExtAudio-0.oma to wav.
