BFSTM (Binary caFe STream) is an audio file format developed by Nintendo for streaming audio data in games on platforms such as the Wii U and Nintendo 3DS. It stores compressed or PCM audio streams used for music and sound effects that are played back in real time rather than loaded entirely into memory. The format is part of Nintendo's internal sound engine toolset used across several game titles.
