To see what can be done in music modding and have a reference point, there are examples such as [https://gamebanana.com/gamefiles/10178 Lylah's Complete Music Overhaul] which has modded over 210 music files in the game that function just how the base game's files do, employing the methods found here. | To see what can be done in music modding and have a reference point, there are examples such as [https://gamebanana.com/gamefiles/10178 Lylah's Complete Music Overhaul] which has modded over 210 music files in the game that function just how the base game's files do, employing the methods found here. | ||

BFSTMs are the main music files in this game, which you can find under content/Sound/Resource/Stream in the unpacked base game folder and DLC music in the Update Data folder. When making a mod, always treat it as an 'update' so anything you make goes in one 'content' file structure. | BFSTMs are the main music files in this game, which you can find under content/Sound/Resource/Stream in the unpacked base game folder and DLC music in the Update Data folder.

This guide will go through how to replace the Temple of Time music as an example, and then the Guardian BGM later as it needs more steps. To mod only the former, only the 1st and 2nd resources listed below are required, but it is recommended to obtain everything in the list to make modding simpler in the future. | This guide will go through how to replace the Temple of Time music as an example, and then the Guardian BGM later as it needs more steps.

First, preview the actual original game file you're replacing so that you are aware of how long it is and what constraints you should roughly keep your new file in (there's nothing wrong with making a loop a minute or so longer than normal for BGM_Spots, but it is not recommended for other tracks as it may function abnormaly). | First, preview the actual original game file you're replacing so that you are aware of how long it is and what constraints you should roughly keep your new file in (there's nothing wrong with making a loop a minute or so longer than normal for BGM_Spots, but it is not recommended for other tracks as it may function abnormaly). | ||

Make the edits as you wish to your file, such as volume adjustment (ideally near the original file's), reverb, fades, equalising, mixing, etc. If the file is very 'droney' (like a choir) with little percussion or fades out, you can do an easy trick as shown below. | Make the edits as you wish to your file, such as volume adjustment (ideally near the original file's), reverb, fades, equalising, mixing, etc. If the file is very 'droney' (like a choir) with little percussion or fades out, you can do an easy trick as shown below. | ||

Click 'Start' and then a prompt should appear allowing you to enter your loop data in samples, which will be simple since you made a note of the points earlier. Ensure the 'Enable' and 'Loop' boxes are checked, and click 'Okay'. This should output your wav as a BFSTM with the loop data written onto it. Rename your new track to the original name of the track you wanted to replace. It is now ready to be used in your mod. BFSTMs are stored under content/Sound/Resource/Stream. | Click 'Start' and then a prompt should appear allowing you to enter your loop data in samples, which will be simple since you made a note of the points earlier.

Some tracks need to be loaded in by a one-second prefetch that contains compressed data of the BFSTM, and you can find these by analysing the list of .bars file to see if your track has one. All sound effects and battle themes have a bfstp stored inside a respective .bars file, e.g: ''GuardianBGM.bars'' contains the prefetches for the main Guardian theme and outro. Assuming you followed the same looping steps as mentioned above, you should have a Guardian_Main theme that loops, and a Guardian_Outro that does not loop (select 'Keep as non-looping' in Looping Audio Converter). Once the new BFSTMs have been made, you should follow the [https://gamebanana.com/tuts/12856 bfstp fixer] method, where you place bfstpfixer.py, BCFSTM-BCFWAV-Converter, your BFSTMs, and a .bat file with the following code: | Some tracks need to be loaded in by a one-second prefetch that contains compressed data of the BFSTM, and you can find these by analysing the list of .bars file to see if your track has one.

A backup .bars file will be generated once you do so that contains the bars data before you made any edits, and the original file is now updated with your new data.

Almost every sound effect in the game is in .bfwav format, and are also stored in .bars files. Any replacement BFWAV you make has to be the shorter than or the exact same length as the original file you are modding, which you can check by opening it in Foobar2000. Assuming you have made your new sound effect in .wav format comply with this, you can simply drag it over the NW4FWaveConverter.exe and it should output a new bfwav of your file. Then, using the Bars tool as previously mentioned, replace the old bfwav with your new one and implement the new .bars file into your mod. | Almost every sound effect in the game is in .bfwav format, and are also stored in .bars files.
