Цитата: Сообщение от MFS У всех XA/STR-файлов стандартный 44-байтный заголовок

Что-то много 44 байта... в спецификациях читаю - 8 байт (и в файлах BBLIT и CTR совпадает)

XA Subheader Information

XA Subheader Information
========================


XA subheader information is 8 bytes, 2 blocks of 4 bytes, each block being identical.


Byte Offset
0 file number
1 channel number
2 submode
3 coding info
4 file number
5 channel number
6 submode
7 coding info


Byte 0, File Number
=============
0 standard data file
1-255 interleaved


Byte 1, Channel Number
======================
0-15 ADPCM
0-31 Data/Video
ADPCM data can only be up to 16 channels, this would be reduced to 8 if the PlayStation didn't have double speed CD-ROM access


Byte 2, Submode
===============
Split into 8 bits:
Bit# Field Description
7 EOF set at end of file
6 Real time sector
5 Form
4 Trigger for use with application
3 Data set if data sector
2 Audio set if audio sector
1 Video set if video sector
0 EOR end of record


Byte 3, Coding Information
==========================
Split into 8 bits:
Bit# Field Description
7 Reserved 0
6 Emphasis emphasis
5,4 Bits per sample 00 = 4bit (level B/C)
01 = 8bit (level A)
3,2 Sample rate 00 = 37.8kHz (level A/B)
01 = 18.9kHz (level C)
1,0 mono/stereo 00 = mono
