Bill, do you prefer 15 ips for 1/2" 2 trk?



Depends on the machine. I can say overall, yes.

Noise VS guide quality here.

Noise can be reduced. Tape bounce cannot.

Tape bouce?  You speak of it as though it's a natural phenomenon... If the tape is bouncing off of your heads at ANY speed, then you have got a problem in the transport.  Maybe you're talking about scrape flutter?  In this case, a scrape flutter idler will do the trick, and it actually pushes the flutter frequency higher when operating at 30ips, which is the purpose of the idler (to cut the scrape flutter into two different, higher frequencies, which are much less audible).

MCI tried to sell an 18 ips machine for a while. I don't remember if this was also the 3" 32 track.

The guy who devised the NAB curve at Ampex admits that it was a kludge to flatten out the Ampex 300's response and deal with the hum. The CCIR curve actually has some real engineering behind it.

It was the 3" 32 trk... and I believe it ran at 20ips.

I totally agree with Steve that if you are running at 15 ips than you will be better off with a CCIR alignment, this the way it used to be before NAB.
Now I also do not use or like Dolby SR but funny enough since Eddie Kramer is one of my best friends, I know he loves and uses Dolby SR. As I post today, I just got off the phone with him from the studio he is in here in LA and was making sure his session is going smoothly. I found out his Dolby rack was incorrectly aligned and it caused him to lose some time. I hate those things ...they are so fickle ...

15 IPS is an interesting beast, for me, if properly aligned, it tends to be more even across the spectrum even with the noise.
