@ -74,6 +74,7 @@ Custom STREAMFILEs wrapping base STREAMFILEs may be used for complex I/O cases:
- data needs decryption (`io_streamfile`)
- data must be expanded/reduced on the fly for codecs that are not easy to feed chunked data (`io_streamfile`)
- data is divided in multiple physical files, but must be read as a single (`multifile_streamfile`)
Certain metas combine those streamfiles together with special layouts to support very complex cases, that would require massive changes in vgmstream to support in a cleaner (possible undesirable) way.

#### DSP DECODING COEFFICIENTS [REQUIRED for DSP]
DSP needs a "coefs" list to decode correctly. These are 8*2 16-bit values per channel, starting from `coef_offset`.
Usually each channel uses its own list, so we can set the separation per channel, usually 0x20 (16 values * 2 bytes). So channel N coefs are read at `coef_offset + coef_spacing * N`

```
#### ADPCM STATE
Some ADPCM codecs need to set up their initial or "history" state, normally one or two 16-bit PCM samples per channel, starting from `hist_offset`.
Usually each channel uses its own state, so we may need to set separation per channel.
State values can be little or big endian (usually BE for DSP), set `hist_endianness` directly or in an offset value where ´0=LE, >0=BE´.
Normally audio starts with silence or hist samples are set to zero and can be ignored, but it does affect a bit resulting output.
Currently used by DSP.

The parser is fairly simplistic and lax, and may be erratic with edge cases or behave unexpectedly due to unforeseen use-cases and bugs. As filenames may contain spaces or #, certain name patterns could fool it too. Keep in mind this while making .txtp files.
