 One of the first games to use ADX was Burning Rangers, on the Sega Saturn.Notably, the Sonic the Hedgehog series from the Dreamcast generation up to at least "Shadow the Hedgehog" have used this format for sound and voice recordings.On top of the main ADPCM encoding, the ADX toolkit also includes a sibling format, AHX, which uses a variant of MPEG-2 audio intended specifically for voice recordings and a packaging archive, AFS, for bundling multiple ADX and AHX tracks into a single container file.
