"Mount & Blade: Warband" is a medieval combat simulator for Microsoft Windows-based computer systems. Music files for "Warband" are stored in the "Music" subfolder of the main directory and are encoded in the Ogg Vorbis file format. You can replace the default music files with your own by converting your music files to the Ogg Vorbis file format and replacing the files in the "Music" subfolder with your own files. Each music file is linked to a specific condition in "Warband" and you may need to replace several music files with your own to cover one specific condition, such as combat or shopping.
Launch GoldWave and click the "Open" option under the "File" menu. Navigate the "Open Sound" Web browser window to the folder with the music file you wish to use with "Warband" and double-click the music file. GoldWave will open the music file and display the audio data in the main GoldWave window.
Click the "Save As" option under the "File" menu. Navigate the "Save Sound As" Web browser window to your "Warband" directory, located in "C:\Program Files\Mount&Blade Warband." Steam versions of "Warband" are located in "C:\Program Files\Steam\steamapps\common\mountblade warband."
Double-click the "Music" folder in your main "Mount & Blade: Warband" directory to enter the folder. Click the "Save as type" drop-down menu and select the "Ogg" file format. Double-click on a "Mount & Blade: Warband" music file to overwrite, then click the "Yes" button in the "Confirm Save As" window. Your music file will overwrite the stock music file and will play in "Warband" when triggered.
Create a backup of any music files you plan to overwrite. You can then revert the changes made if your custom music doesn't fit the situations in which it's played. Each music file only plays in a specific situation, such as when fighting against a specific faction or travelling through a specific area. Make sure you overwrite the correct file variation when inserting your custom music.
