current version: 3.4.1 (December 17, 2012)
Download (C# source code)

Changes in 3.4.1:

• Fixed a bug that made BRSTM loop points unreadable when there was a space in the file path

Changes in 3.4:

• Fixed a bug that made every VGM loop, even when it wasn't supposed to

Version 3.2, which uses Java, is still available here.

BRSTM Converter is a program written in Visual C# with BrawlLib (and using other programs, like SoX, to do the actual conversion). You can use it 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 (also through SoX)
• 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)

Supported output formats include:

• WAV, FLAC, Ogg Vorbis
• BRSTM (using BrawlLib)
• .logg (looping Ogg Vorbis file; can be played with vgmstream)

For more information, use the Help menu on the program's initial options dialog.

The program supports command-line arguments (use the --help argument for more information.)

Known bugs:

• BrawlLib won't work with Mono, so it's Windows-only. .NET Framework 4.0 is required.

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

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.
