I'm looking for some advice/info. I sometimes transfer reel-to-reel tapes to CD or digital files for my customers. Frequently, I receive 3 inch tapes from the 1960s that start at one speed and gradually speed up or slow down substantially as the tape plays. The speed range is usually between 1 7/8 and 3 3/4, but never landing on either speed. I can correct for this using Adobe Audition's gliding stretch, but it takes quite a bit of trial and error. What sort of tape player would I need to hunt down to play these tapes correctly without having to resort to a software solution? My customers never have any idea what brand and model was used to make the recordings.
