+
+> Play a wide variety of audio formats used in video games and convert them into `wav`.
+> More information: <https://vgmstream.org/doc/USAGE>.
+
+- Decode an `adc` file to `wav`. (Default output name is `input.wav`):
+
+`vgmstream_cli {{path/to/input.adc}} -o {{path/to/output.wav}}`
+
+- Print metadata without decoding the audio:
+
+`vgmstream_cli {{path/to/input.adc}} -m`
+
+- Decode an audio file without loops:
+
+`vgmstream_cli {{path/to/input.adc}} -o {{path/to/output.wav}} -i`
+
+- Decode with three loops, then add a 3s delay followed by a 5s fadeout:
+
+`vgmstream_cli {{path/to/input.adc}} -o {{path/to/output.wav}} -l {{3.0}} -f {{5.0}} -d {{3.0}}`
+
+- Convert multiple files to `bgm_(original name).wav` (Default `-o` pattern is `?f.wav`):
+
+`vgmstream_cli -o {{path/to/bgm_?f.wav}} {{path/to/file1.adc}} {{path/to/file2.adc}}`
+
+- Play the file looping endlessly (`channels` and `rate` must match metadata):
+
+`vgmstream_cli {{path/to/input.adc}} -pec | aplay --format cd --channels {{1}} --rate {{44100}}`
