Usage:
ofr [command] [options] src1 [--output dst1] src2 [--output dst2] ...

Commands:
  --encode            encode WAV/RAW file(s) to OFR file(s)
  --decode            decode OFR file(s) to WAV/RAW file(s)
  --info              print information about OFR file(s)
  --verify            quick verify integrity of OFR file(s)
  --check             check raw PCM input data MD5 of OFR file(s)
  --help              display detailed parameter reference

Options:
  --preset level      use compression preset level, defined as
    0:  1.00x 0.00% # --mode fast --optimize none --no-aca
    1:  1.02x 0.54% # --mode fast --optimize none --aca
    2:  1.42x 1.56% # --mode normal --optimize fast --aca
    3:  2.17x 1.90% # --mode high --optimize fast --aca
    4:  2.57x 2.45% # --mode turbonew --optimize fast --aca
    5:  2.90x 2.62% # --mode fastnew --optimize fast --aca
    6:  3.41x 2.78% # --mode normalnew --optimize fast --aca
    7:  4.26x 2.94% # --mode highnew-light --optimize fast --aca
    8:  5.10x 3.06% # --mode extranew-light --optimize fast --aca
    9:  8.77x 3.33% # --mode bestnew-light --optimize fast --aca
   10: 11.57x 3.41% # --mode ultranew-light --optimize fast --aca
  max: 11.68x 3.47% # --mode ultranew-light --aca --acm --optimize best

        first column is average decoder complexity relative to preset 0
        second column is average compression gain relative to preset 0
        third column contains the equivalent options for the preset

        all presets also include --seek normal, which is the default
        +1000 can be added to any preset to activate --acm
        +2000 can be added to any preset to activate --optimize best
        preset max is currently equivalent with preset 10 + 1000 + 2000
        the default preset is 2 and it is implicitly activated

This is the short help. For detailed command refrence, use --help
