Anyone know of any software to correct stereophases?

I have a lot of cassettes which I want to transfer to digital. I use to adjust the azimuth angle of the playbackhead as goo it is possible but sometimes the angle varies. At my job (working at tv-station) we have hardware for this but is there any software available which can manage this? I have found "Advanced audio corrector" but is not shure if that can do this...

I have read that "Sonic Solutions" can do this, but I have never used it. Too expensive for me. Good luck

Basically, any software which will allow you to change the time relationship between left and right channels will do what you want.

Unfortunately, this is a feature which is not that common - CEP certainly won't do it and neither will a lot of the more common software around.

Off the top of my head, the only two that come to mind are Wavelab and DC-ART32, although I'm sure someone will come up with some more.

DC-ART32 is useful as you can actually preview the result while changing the time relationship between the two tracks. This function is profided for the very purpose of correcting incorrect azimuth alignment.

Thinking about it, I suppose you could write the left and right tracks of a stereo mix to individual channels in multitrack mode and then move one of those to the correct time relationship. Then recombine by mixing these two individual tracks. I'm not a multitrack expert when it come to CEP but I guess someone will have tried doing this and will confirm if that is the way in CEP.

Personally, I can't be bothered with all this nonsense. To my mind it it easier to adjust the playback machine to compensate for any errors (just be sure you have a means of correctly re-aligning after you have done).

I recently found that one of my tapes had this problem. Not knowing if there was a 'proper' way to correct it, or different software I used CEP. It was very very very very time consuming, and not straightforward to me at all. Essentially you do what Graeme suggests and in zoom get to a point where you are adding/subtracting ms in one track and then zooming out to hear the result. It worked but since in my case the phasing was not even throughout the tape I had to check constantly at different places in the recording and correct again. This became right on the edge of not worth it. For me it was because it was the only recording of a concert that existed and I don't have adjustment capabilities with my current tape player.-j

Well, since Frybyte has managed to do this, it seems that my proposed method of solving this problem using CEP is possible but long winded - which is just about the situation I imagined.

For me, if I am goinf to try and correct azimuth faults electronically, then DC-ART32 is the easiest solution I have come across so far - in fact it's probably one of its most useful functions.

Graeme-
I did wonder what was happening to email[s too many I admit]. Hope things smooth out before I'm due as I don't have phone# for emergencies.
As for the tape deck being adjustable- yes you are correct If IF I took it apart to adjust I'd have an awful time putting it right.
Hopefully thbe you didn't get the idea that I'm recommending this method- I'm not.
If it wasn't a unique situation I would have never attempted it at all, and the end result was just to make something horrid and unlistenable into something tolerable.-j
