virtual int32 GeneratePCMData
(
uint8 * PCMData,
const int32 SamplesNeeded
)

Remarks

This is only used for DTYPE_Procedural audio. It's recommended to use USynthComponent base class for procedurally generated sound vs overriding this function. If a new component is not feasible, consider using USoundWaveProcedural base class vs USoundWave base class since as it implements GeneratePCMData for you and you only need to return PCM data.
