NDS Sound Extractor is a command line program to extract sound sequences and samples as .midi and .wav from a DS ROM. The original site for it does not have the program anymore, so you may get it from here: [1].


Usage  : ndssndext.exe [options] <file...>
    -x            extract files only(no decoding)
    -s            show processing status
    --help        show this usage

You can also drag an .nds ROM onto the program and it will automatically create a folder and extract mid and wav files inside subfolders named Sequence, Stream and WaveSample.

Extracting Raw Data[]

This program can also extract the raw .sseq, .strm and .swar files without converting them with the "-x" option:

ndssndext.exe -x file.nds
