Defined in carb/audio/IAudioData.h

constexpr DataFlags carb::audio::fDataFlagFormatPcm = 0x00000002

the data was loaded as WAV PCM.

This flag will be added to the sound data object upon load to indicate that the original data was loaded from a PCM WAV/RIFF file. If specified before load, this flag will be ignored and the load will behave as though the data format flag were specified as fDataFlagFormatAuto. This format flag is mutually exclusive from all other fDataFlagFormat* flags.
