Vodoley, один VAB файл создаётся из двух - VH и VB. Заголовок VH файла содержит acsii строку pBAV.
The VH file is a header for the soundbank (VB), detailing information on pitch, keynote, reverb, etc. used for samples. The VH file concludes with a 512 byte index containing the size of each sample located in the coresponding VB (soundbank).
The VB file is a compilation of ADPCM-encoded sound samples, specially encoded for use with the PSone's SPU. The VB can contain anywhere from 1-254 sound samples, and has it's own pointer index, with each offset being right-shifted by 3 bits per pointer.
