current version: 3.1 (April 18, 2012)
Download (source code included in JAR)

Changes in 3.1:

• Removed JLayer - MP3 support now uses libmad via SoX
• Support for alternate output formats:
  • WAV
  • FLAC
  • Ogg Vorbis
  • .logg (looping Ogg)
  • MP3, if libmp3lame.dll is present
• New, nicer-looking help dialog
• Code refactoring - more of the work is now in the Music class, rather than in Main

Changes in 3.0:

• Renamed - used to be "Rate Converter"
• Redesigned options dialog
• Direct support for MP3 files using JLayer
• Direct support for VGM/VGZ files using VGMPlay
• Revolution B build code ported to Java from C

BRSTM Converter is a program written in Java (but using other programs, like dspadpcm, to do the actual conversion) that you can use to do batch conversions to BRSTM and/or batch modifications of certain audio attributes:

• lower the sample rate (absolute or relative), to reduce file size
• convert to mono - for stereo sound, it cuts the file size in half
• amplify audio by a given factor (in amplitude or dB)

Supported input formats include:

• WAV, FLAC, Ogg Vorbis, and any other format supported by SoX (full list)
• MP3 (through JLayer)
• BRSTM and any other format supported by vgmstream (full list from README)
• VGM/VGZ (through VGMPlay)
  You can find VGM packs at:
  • SMS Power! (Master System, Game Gear)
  • Project 2612 (Sega Genesis)
  • vgmrips (Other)

For more information, click the Help button on the program's initial options dialog.

The program supports command-line arguments (run java -jar "BRSTM Converter.jar" --help for more information.)

Known bugs:

• Running it with Linux+wine is slow, but it should work. (Use the native Java; the program will try to launch Wine when calling SoX, VGMPlay, test.exe or dspadpcm.)

Output .brstms are put in the "output" folder.

You'll need the Java Runtime Environment: http://java.com/

Note: on the "file open" dialog, you can hold down Ctrl to select multiple files at once before clicking OK.

How to use loop.txt: specify a loop start, a loop end, and a filename on each line, like so:

853168 5087322 41 Carefree Action.wav

The program should automatically adjust both the start and end points for you if the start point is not divisible by 14336.
