mostly Daws work with wav 32/64 bits ( no dithering audio ) . that’s why often the sounds seems more accurate / clearely on our DAW .
keep in mind even you play a sounds 44. khz 16 bits on your daw , your daw for playplack streaming do a copy on 32 bits or 64 bits . On UE4 engine , the audio files played as the original sample rate .
