kawashima is a library to decode CRI HCA audio. It is named after Mizuki Kawashima.
Its original code is from here, in public domain. Some adaptations are made to pack the functions into a shared library.
For how-tos, please see the API docs or example project.
Beware that, if you want to integrate the library or any piece of code, DO AT YOUR OWN RISK.
hcaenc is used to encode an HCA audio file from a WAVE audio file.
Internally it calls hcaencEncodeToFile API in hcaenc_lite.dll
included in ADX2LE suite.
Usage:
hcaenc.exe <input WAVE> <output HCA>Example:
hcaenc.exe input.wav output.hcaPlease note that the HCA encoded by hcaenc_lite.dll is always statically
encrypted (cipher type 1). Its sampling rate is fixed at 44100 Hz.
Due to copyright reasons, hcaenc_lite.dll is not supplied in this repository.
Please download ADX2LE suite manually.
hcacc is a utility that can convert HCA files from one cipher type to another.
Usage:
hcacc.exe <input HCA> <output HCA> [-ot <output HCA cipher type>]
[-i1 <input HCA key 1 (if necessary)>] [-i2 <input HCA key 2 (if necessary)>]
[-o1 <output HCA key 1>] [-o2 <output HCA key 2>]The valid cipher types are:
0(not encrypted);1(statically encrypted);56(encrypted with a key pair).
The cipher type of the input HCA file is automatically detected, and it cannot be set by code.
Example:
hcacc.exe input.hca output.hca -ot 0
hcacc.exe input.hca output.hca -ot 56 -o1 AABBCCDD -o2 01020304Assume we are using an HCA file encoded by hcaenc (or hcaenc_lite.dll),
and this command will convert the whole input.hca from cipher type 1 to
cipher type 0, and write to the new file output.hca.
This utility is extremly useful when creating HCA files for games. Since
hcaenc_lite.dll is hardcoded as type 1-only, the encoded HCA may not be
accepted by games that use type 56 (which also have independent key pairs)
or type 0 HCA audio files. A little conversion should do the magic and
solve this problem.
