Simply create a file named `(filename).txtp`, and inside write the commands described below.
## TXTP features
## TXTP FEATURES
### Play separate intro + loop files together as a single track
- __Ratchet & Clank (PS2)__: _bgm01.txtp_
Some games clumsily loop audio by using multiple full file "segments":
__Ratchet & Clank (PS2)__: _bgm01.txtp_
```
# define several files to play as one (there is no limit)
# define 2 or more segments to play as one
BGM01_BEGIN.VAG
BGM01_LOOPED.VAG
# multi-files must define loops
# segments must define loops
loop_start_segment = 2 # 2nd file start
loop_end_segment = 2 # optional, default is last
```
Channel number must be equal, mixing sample rates is ok (uses first).
#channel number must be equal, mixing sample rates is ok (uses first)
If your loop segment has proper loops you want to keep, you can use:
```
BGM_SUMMON_0001_01-Intro.hca
BGM_SUMMON_0001_01-Intro2.hca
BGM_SUMMON_0001_01.hca
loop_start_segment = 3
loop_mode = keep # loops in 3rd file's loop_start to 3rd file's loop_end
```
```
bgm_intro.adx
bgm_main.adx
bgm_main2.adx
loop_start_segment = 2
loop_end_segment = 3
loop_mode = keep # loops in 2nd file's loop_start to 3rd file's loop_end
```
### Multilayered songs
TXTP "layers" play songs with channels/parts divided into files as one (for example main melody + vocal track).
__Nier Automata__: _BGM_0_012_song2.txtp_
```
# mix dynamic sections (2ch * 2)
BGM_0_012_04.wem
BGM_0_012_07.wem
mode = layers
```
__Life is Strange__: _BIK_E1_6A_DialEnd.txtp_
```
# bik multichannel isn't autodetectable so must mix manually (1ch * 3)
BIK_E1_6A_DialEnd_00000000.audio.multi.bik#1
BIK_E1_6A_DialEnd_00000000.audio.multi.bik#2
BIK_E1_6A_DialEnd_00000000.audio.multi.bik#3
mode = layers
```
Note that the number of channels is the sum of all layers, so three 2ch layers play as a 6ch file.

### Multilayered songs
TXTP "layers" play songs with channels/parts divided into files as one.

BIK_E1_6A_DialEnd_00000000.audio.multi.bik#3
mode = layers
```
Note that the number of channels is the sum of all layers, so three 2ch layers play as a 6ch file.
### Channel swapping/mapping
TXTP can swap channels for custom channel mappings. It does "swapping" rather than simpler "mapping" since vgmstream can't read a format's mappings or guess which channel is which. Format is:
```
#ch1 = first
file1.ext#m2-3 # "FL BL FR BR" to "FL FR BL BR"
#do note the order specified affects swapping
file2.ext#m2-3,4-5,4-6 # ogg "FL CN FR BL BR SB" to wav "FL FR CN SB BL BR"
```
Note that channel masking applies after mappings.
### Custom play settings
Those setting should override player's defaults if set (except "loop forever"). They are equivalent to some test.exe options.
- __God Hand (PS2)__: _boss2_3ningumi_ver6.txtp_ (each line is a separate TXTP)
__God Hand (PS2)__: _boss2_3ningumi_ver6.txtp_ (each line is a separate TXTP)
```
# set number of loops
boss2_3ningumi_ver6.adx#l3
@ -136,6 +142,19 @@ boss2_3ningumi_ver6.adx#l1.5#d1#f5
For segments and layers the first file defines looping options.
### Force sample rate
A few games set a sample rate value in the header but actually play with other (applying some of pitch or just forcing it)
__Super Paper Mario (Wii)__
```
btl_koopa1_44k_lp.brstm#h22050 #in hz
```
__Patapon (PSP)__
```
ptp_btl_bgm_voice.sgd#s1#h11050
```
### Force plugin extensions
vgmstream supports a few common extensions that confuse plugins, like .wav/ogg/aac/opus/etc, so for them those extensions are disabled and are expected to be renamed to .lwav/logg/laac/lopus/etc. TXTP can make plugins play those disabled extensions, since it calls files directly by filename.

## TXTP parsing issues
## TXTP PARSING ISSUES
*Commands* can be chained, but must not be separated by a space (everything after space may be ignored):
```
bgm bank.sxd2#s12#c1,2 #spaces + comment after commands is ignored
@ -193,34 +212,14 @@ loop_start_segment = 1 #spaces surrounding value are ignored
```
```
bgm.sxd2
config = #s12#c1,2 #must not have spaces once value starts until end
commands = #s12#c1,2 #must not have spaces once value starts until end
```
The parser is very simplistic and fairly lax, though 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.
## Mini TXTP
## MINI-TXTP
To simplify TXTP creation, if the .txtp is empty (0 bytes) its filename is used directly as a command. Note that extension is also included (since vgmstream needs a full filename).
- _bgm.sxd2#12.txtp_: plays subsong 12
- _Ryoshima Coast 1 & 2.aix#c1,2.txtp_: channel mask
- _boss2_3ningumi_ver6.adx#l2#F.txtp_: loop twice then play song end file normally
- etc

_Join "segments" (intro+body):_
```
#files must have same number of channels

loop_start_segment = 2
```
_Join "layers" (ex. main+vocals):_
```
#files must have same number of samples
