## Utilities
### `cmd/decode`
Example application that decodes files and provides some general information about the decoded streams, and produces an MD5 hash of the sample data.
Run via `$ go run git.gammaspectra.live/S.O.N.G/Kirika/cmd/decode -input "resources/samples/cYsmix - Haunted House/11. The Great Rigid Desert.flac"`
Example output:
