libcgss

libcgss is a helper library originally for THE iDOLM@STER Cinderella Girls Starlight Stage (CGSS). It provides both C and C++ API for HCA audio and ACB archive manipulation.

The project consists of a library (libcgss) and several other applications.

Library (libcgss)
- takamori: Base structure: streams and exceptions.
- ichinose: CRI ACB/AWB archive reader.
- kawashima: HCA decoder, migrated from kawashima.
Applications
- hcaenc (obsolete): HCA encoder. Requires hcaenc_lite.dll^[1]. C# equivalent
- hcacc: HCA cipher converter. C# equivalent
- hca2wav: HCA decoder. C# equivalent
- hcainfo: HCA info viewer.
- utftable: UTF table schema explorer, similar to utf_tab.
- acbunpack: ACB archive unpacker. C# equivalent
- acb2wavs: Batch converter for HCAs in ACB. C# equivalent
- acb2hcas: Batch exporter for HCAs in ACB. Generates companion .hcakey files for vgmstream.
- hcaenc: HCA encoder based on VGAudio/VGAudio-CPP. Does not rely on hcaenc_lite.dll.
- hcadec: HCA decoder based on VGAudio/VGAudio-CPP.

This project has a sister project DereTore. However the strength of C API is better interoperability with other libraries. The pure C# version of hcaenc and hcacc can be found in DereTore as applications.
If you are looking for a faster HCA decoder with higher definition for *NIX and you are a DIY person, have a look at this.
If you are looking for a small native application for HCA encoding/decoding, have a look at this.
