Hi everybody, I'm not sure if this is the right forum. If not, please move it to its proper home. My office sometimes receives 911 audio cassette tapes that we must copy and provide to attorneys and/or prosecutors. We have a Sony dual cassette deck in the office and it has the capability to perform high speed dubbing, but I've been reluctant to do this, because I'm afraid the sound quality will suffer. The tapes are poor quality to begin with, so any additional quality loss would not be acceptable. Am I worrying for nothing? Will high speed dubs sound just as good as a tape made at normal speed? Many thanks.
