Modding Your In-Game Music

Been putting together a document to help organize all the files and names, figured I might as well make this public.

Introduction

Hello Thors students, I am Instructor Makarov and I'll be teaching you how to modify and customize your own in-game music. This course will cover:

• How to modify the in-game audio files.

• Which files are which.

• Troubleshooting.

Thank Falcom the goddess Aidios this process is incredibly easy, meaning the only person who should be failing is Mint. Don't delete System32 and you will be doing much better then her.

WARNING

There are some mild spoilers in this guide. Nothing explicitly saying what happens, but it might clue you into things that will happen. I'll do my best to mark spoilers, but I might miss something so be careful to those who haven't beaten the game yet.

How to mod your music

0). (optional) download the Lossless Audio Pack DLC (It's FREE!) , it'll add higher quality '.wav' files for all game audio. That and '.wav' files are significantly easier to deal with then '.opus' files. it's about another 10-15 gb's but it's worth it.

1). Find the music folder for the game. On a Windows PC the path should be as follows:
Steam>steamsapps>common>The Legend of Heroes Trails of Cold Steel IV > data > bgm



You can also find this quickly by going to the game page in your Library, right clicking on CS4, manage > browse local files.


2). You are now faced with a wall of confusingly named audio files...


Do not be afraid, I assure you they don't bite. Patrick has dealt with worse trying to get close to Elise. You can click on anyone of these and listen to them, you will probably recognize a number of these.

3). Changing music is as simple as replacing the current file with another with the same file format (.wav) and the same name format (edxxxx).

• Let's start easy, ed8007 is the file name for the title screen. We will replace this '.wav' with another.

• Create another folder somewhere else on the computer and take the original out (CS4 title screen theme).

• Put new file of choice in the "wav" folder and rename it to "ed8007". (make sure the original is not in this folder anymore or else windows will give you grief.)

• Boot up the game to the title screen and your new music of choice will play.

If the music played congratulations *headpat*. This process works with ALL AUDIO FILES, not just the music. find the "voice" folder for the voice audio files, and "se" for sound effects. It is only a matter of matching file and naming formats.

To make your modding (and my modding) easier the next section covers what files are what. I don't plan on listing every track, just the battle music, dungeon music, and some other miscellaneous tracks.

If the music did not play, don't get too worried I have a troubleshooting section down below to help out.

--Important Note--

I've modded music files for CS1/2 doing this same process, it works. One difference I've noticed is that those games will automatically loop the music when it reaches the end of the file, CS4 has not automatically looped the file when it reaches the end. If anyone knows how to do this please let me know, I would love to know.

Troubleshooting/FAQ's

Issues/Troubleshooting

These are issues I've come across:

• In CS1/2 if the file is too long (30 mins+) the file would not play. In my testing CS4 can handle audio files longer than 2 hours. I don't know the limit to what CS4 can handle but if you need more than 2 hours of looped music what are you doing?

• The file must be ".wav" for it to work (or .opus if you didn't download the audio DLC pack).

• If you are converting files from other formats to ".wav" make sure you export at 16 bit resolution, otherwise your game will crash.

• For those who missed my note earlier, unlike CS1/2 this game doesn't automatically loop music files when they finish. If anyone is aware of how to get them to loop please let me know. If anyone knows how to get music to loop cleanly that information will also be appreciated.

• Occasionally I come across a song that the game will compress when it plays in game. This comes in the form of playing at a higher pitch and faster tempo (speed). The way I've gotten around this is by going into my preferred audio editing program (Audacity) and using the "Change Speed" effect. This effect can change the pitch and tempo, lowering both will counteract the compression the game uses. In normal playback it will sound weird, but it playback normal in game.
  
  
  The important settings to take from this screenshot is the "Speed Multiplier" and the "Speed Change", everything else in this screenshot doesn't matter. These settings have worked on both CS1 and CS4. The way I calculated these settings is by timing the playback in-game while compressed, took the difference into my editing software and had the software add that length to song. When editing your song make sure you edit both speed and pitch.

These are just the issues I've come across, if anyone has issues they've come across let me know and I'll add it.

Does this work with previous Trails games?

I've done this same process in CS1/2 with the same results, any other game I am unsure but it's probably the same. As mentioned before, the process is as simple as matching the file format and the naming format.

Does this work Ys games?

No idea, I haven't played those games.

Do I use any audio edting/converting softwares

For audio editing I use Audcaity
(I've heard some shady things about modern Audacity so you can look for Dark Audacity as well)

There are some file formats Audacity doesn't work with/recognize, so I recently downloaded MediaHuman Audio Adapter and that has worked well so far.

If anyone has any good suggestions feel free to list them.

Kudos for naming all opus files )

do you know what the heartbeat sound effect is? I want to mod it into the vine boom sound effect

[BEYOND THE TIME]

Thank you for making this. I will definitely make use of it in my next playthrough.
