Title: Half-speed dubbing?
Post by: imacdv50 on February 03, 2011, 12:21:34 PM: OK, I have a number of mono micro-cassettes I would like to preserve on digital. Would there be any advantage to transferring them at half-speed and speed them up in post-processing? Maybe dubbing them to my M10 at 96/24. Would that give me more options in post?

Thanks for your input (pun intended), David

then a 24 bit transfer
sine they are on micro, what would your final product be? CDR? then just go 24/44.1 - if it's gonna be DVD the go 24/48 no reason to use 96k for comprimised sources
others will tell you
different - I'm sure

Way overkill to go 24 bit unless it is a recording of God or of global importance IMHO. Speed correction is just a pitch adjustment that any decent DAW can do.

The tapes were of Tahitian dancers and percussion recorded at full speed on the micro Sony. The recorder has the option of half-speed record and playback. I will most likely save them as wave files on CD/DVD data disks.
