You cant do that with out a tape that is in proper alignment for your deck. You need a alignment tape try contacting the company that made your deck and see if you can purchase one from them.
You cant align every tape to your deck or your deck to every tape that would take forever.. But you can make sure your deck is in good alignment to it self. Any other tape deck you used for recording should be pretty close.
Hi Chris,
My understanding was that a "test signal tape" is only good for restoring the deck to factory settings, ie. the optimal alignment for playback of commercial prerecorded tapes. It has been discussed here:
http://taperssection.com/index.php/topic,44898.0.html
Since my masters were exclusively recorded with a Sony WM-D3, I need to align the head especially for this scenario. So I need to roll one of my own actual masters while I adjust the azimuth, not the test tape.
It won't be that time consuming - once I got it right, I can stick to that setting for all tapes.
Back to the topic of software. Did anyone try this in realtime while doing the adjustment???

Sorry my bad I did not know that all your other tapes were only on one machine.. The only way to do it would be this.. Take the playback of a tape from one machine * the one you plan on using to dump everything * and then compair it to the original machine record onto your computer both machines at the same time. Then use fft via a waterfall window to compair the two waveforms and "quasi" align them that way.
The thing is this you need that original machine in order to compair the original with the reproduction thru the Nak deck, if you dont have that you dont have a means of comparing the alignment.
If your just looking at frequency response by it self you dont really know what the "actual frequency response is" because you dont have proper azimuth to begin with. So you would not know what you were looking at. And adjusting it until the "frequency response " was the widest might not yield proper azimuth. So all you can do is
A- find the original machine to compair it to the known machine...
B-
Find the alignment tape of the original machine and align the playback heads on your Nak to it.. that's a good possibility BUT DONT do this if you dont have a nak test tape to put your nak back lol hey that ryhmes!
C- Do it by ear and "guess" the alignment.
d- just stick the dam tapes in a play them back..
