A fork from the original OSBExtract by Nick Woronekin

A tool for extracting OSB archives from Dreamcast games. Can also extract OSBs from MLT files, and convert P04 and P16 files to WAV.

OSBExtract -i <file or directory> 
 -i, --input Required. Input files to be processed. Can be files or
 directories.
 Optional:
 -o, --output WAVE output folder (Default is same as input folder).
 -x, --extra Output extra data not included in the OSB to WAVE conversion (Saves to output folder).
 -v, --verbose Set view verbose information used for debugging.
 -s, --sample Use alternate sample rate of 32kHz (Default is 44.1kHz). Appends "(32kHz)" to filename
 --help Display this help screen.
 --version Display version information.

• OSB files now have their data extracted in a dynamic way.
• AMKR, NITS, PALP, EMUN, IPTC, RPCE, and ETTX metadata are successfully skipped during extraction.
• PCM class has been completely rewritten to allow customized attributes if needed.
  • This will be useful in case OSB data is found to have different encodings, such as a different sample rate.
• AicaADPCM2WAV by Sappharad is now used to convert ADPCM data.
• Uses commandline package to assist in handling command line argument options.

• Most games (Illbleed, Seaman, Jet Set Radio for examples)
  • Extracted audio isn't always the correct sample rate

• Figure out proper parsing of MLT header data
• Figure out unknown ADPCM flag meanings
• Figure out how sample rate is correctly determined
