> One reason is that only the transcripts of conversations from Farm Hall survive, not the original recordings. (Those recordings were never kept: Tape-recording technology was in its infancy in 1945, and the conversations were recorded on shellac disks that were resurfaced and reused after their contents were transcribed.) Interestingly, during the war, it was the Germans who had made rapid advances in tape recording technology. It was in that same year that Jack Mullin acquired the German recorders from Bad Nauheim and would later demonstrate their technical superiority to amazed audiences in America: https://en.wikipedia.org/wiki/Magnetophon#History https://en.wikipedia.org/wiki/Magnetophon#History . Astounding to think that if that technology had been disseminated a bit earlier and faster, we might still have access to these recordings.
