You can't get more authentic than this! This was recorded June 6, 2004, at the National D-Day Museum in New Orleans, LA. It is an authentic recording of a fully automatic MG42. This audio can be used to make authentic gun sounds for your game or it can be used as background filler in your level. The file is an avi. The video was compressed, but the audio was left uncompressed (16 bit stereo, 48khz). It should be noted that the developers of Call of Duty used this German re-enactment group for their gun audio, weapons reference and uniform reference.
