Hi, Doug and Steve, This raises the issue: are these variations in orchestra tuning, recording process, or both? https://www.youtube.com/watch?v=UnhlQUBsd6g Cheers, Richard On 2019-04-12 10:00 p.m., Steve Smolian wrote: > Hi, Doug, > > It's not that I have perfect pitch- I don't. I do hear differences in tone, however. Maybe I only think I do, in some cases, but I'm certain of it in others. But I've worked with enough professional musicians to know that it matters to them, especially string players. > > Steve > > -----Original Message----- > From: Association for Recorded Sound Discussion List <[log in to unmask]> On Behalf Of Douglas Pomeroy > Sent: Friday, April 12, 2019 9:13 PM > To: [log in to unmask] > Subject: Re: [ARSCLIST] LP playing speeds > > Hi Steve, > Years ago I started checking the pitch of every single recording which came my way.The tape recorders without servo circuitry, like the Ampex 350 and most non-pro decks are especially difficult to fix. There is some software available for making gradual corrections over time, but these programs are not a panacea. > I would add that a range of 15 to 20 cents is close the the limit of human hearing acuity, at least for those of us without perfect pitch. But I totally agree we should correct alldetectable errors. -- Richard L.
