What would be the best Azimuth settings to use for making certain that a set of high resolution (24/96) transfers are correctly adjusted?
I believe the info in the help files is best suited to cassette tape and I would also like to understand why I should use certain settings as well.

This is a great piece of software - I am about to update it so I can access the de-clipping modes as well
Thanks very much in advance of suggestions.....

In Stereo Tool it doesn't really matter - look at how fast and how far things are moving and adjust the settings accordingly.

If you want to restore lost highs caused by a misaligned tape head as well, you might want to check out my other program, Tape Restore Live!, which contains the same AZIMUTH correction but with highs restoration. Also, it doesn't downsample the audio to around 44/48 kHz (which Stereo Tool does!).

Interesting - I was unaware that it downsampled. So that means if I use it in a 24/96 stream, with the project at 24/96 that the output is essentialy padded? Ouch.
Tape Restore Live - sounds like a winner to me so off to go buy me a copy. Appreciate the tip.
As far as restoring the lost highs goes (especially from recordings that started life as 15IPS and were downgraded to 7.5IPS (or even lower - yuk)) I have been using the Universal Audio Ampex ATR-102 tape emulation very successfully. Are you familiar with it, by any chance? I'd be interested to know what you think of it

I have just noticed that Tape Restore Live is a WinAmp plugin!
Is there a VST version, please? WinAmp is of absolutely no use to me at all, sad to say.

Ow, I just replied in the other topic. Lol. There are 'bridge' programs to run DSP (Winamp) plugins in a VST environment, that might be the best solution. On top of that, Tape Restore Live! is free.

Don't know what that other program does - but when I'm talking about restoring lost highs I mean it detects how bad the tape head was aligned at each moment and compensates for that.

It sounds great, but I worry about running a wrapped plugin (DSP>VST) in a wrapper (32/64 Bit Bridge) - my host software is all 64-bit.
Is there no way a version of StereoTool can be modified to include that functionality?

Not easily. First, there's the downsampling issue. Every other filter in Stereo Tool assumes downsampled input. Also, it doesn't really make sense to restore lost highs - which needs to be done differently depending on the type of tape that was used - in a broadcast processor.

Could you just try if it works?

Alternatively, assuming that you just want the output files, did you know that you can just use Winamp to process a bunch of files and write the output to .wav files again? So if all you want is to process these files, that might be the easiest option. If you do that, you won't loose the high frequencies etc.
