Cool Edit Import - Page 2

Runaway · 09-22-2009, 07:52 PM

Finally got around to looking at earlier versions of AA/CEP and currently have a beta version of AATranslator running which will import CEP 1.2, 1.2a, 2.0 2.1 as well as AA 1.0, 1.5, 2.0 & 3.0. - may look at earlier versions of CEP if there is a demand.

A couple of minor things to sort out and a bit more testing and then we will release it.

I mentioned in my previous post that I had 1 or 2 minor things to sort out. Well for versions AA1.5 & prior it happens to be the panning issue I'm working on. I re-read your initial post and note that you had solved it. From AA2 onwards AA & Reaper share very similar Track panning methods. Prior to AA2 AA uses some 'ratio' of the 2 logarithmic left & right gain values which then have to be converted to Reaper's (and later AA's) more simplified panning method. Sqkychair if you would like to share that ratio it would save me a lot of hair and it would be appreciated.

The only other thing I have top do is write some code to extract the Track gain & Track pan for AA 2 & 3 - the location of the values and what they represent are known - I just have to get to that on my list of things to do :-)

Track Gain & Track Pan for AA2 & AA3 are now sorted out.

Working on the AA1.5 & prior Track Pan then it should all be done and can be sent for testing.

Just now saw this.

The panning is indeed bizarre. I never really worked out how they get their slider value. But, you don't need it!

Just use the RATIO ONLY! The ratio of left to right as stored in the file.

This ratio is what Reaper uses and the resulting pan is correct.

Thanks for the reply.

I had seen in your early posts that you used a ratio to solve it.
As I recall the left & right values are logarithmic values which I can easily convert to db levels but maybe its just me but I could not come up with any ration that either made sense or gave me the right answer.

eg L = .630957344480193 & R = .476430986805416
I would be interested to know how you solved this

This was the only thing i couldn't work out so I left it and am now currently banging my head against a brick wall with OMF2 :-(

Thanks again for the reply

OK, it is simpler than you think!
eg L = .630957344480193 & R = .476430986805416

here is the code in vb
dblLEft = Input L
dblRight = Input R
dblFader = Output for the fader
dblPan = Output for the Pan

Private Sub CalulatePan(ByVal dblLeft As Double, ByVal dblRight As Double, _
ByRef dblFader As Double, ByRef dblPan As Double)
'this will not LOOK the same as cep's pan bar because their slider works on a different scale than
'reaper but should get you very close to the same pan position

If dblLeft = dblRight Then

dblPan = 0
dblFader = dblRight

Else

If dblLeft > dblRight Then

'pan to left
dblPan = 1 - dblRight / dblLeft
dblPan = -dblPan
dblFader = dblLeft

Else

'pan to right
dblPan = 1 - dblLeft / (dblRight)

dblFader = dblRight

End If

End If
LogItem("Pan=" & dblPan.ToString("0.00"))

End Sub

EDIT: the damn indentation does not look right in the post and I cant fix it!

Mate that just tears the fork out of my nightie!

I'm sure I'd tried all the simple solutions - damn!

Thanks heaps for that - now if you knew something about OMF2.... LOL

PM me and I'll give you a free copy of AATranslator to show my appreciation.

BTW

AA Changed the way they stored their track pan AFTER AA1.5 so both AA & Reaper (and a heap of others) are 100% compatible

This should explain what I know about OMF2....WTF is an OMF2?

I can't PM you for some reason. I need instructions, LMAO!

I don't know why you cant PM me - others have - just contact me via the AAtranslator site

OMF2 is a format used by Avid, PT, Sonar and others.

sqkychair · 10-20-2009, 08:59 AM

Runaway,
I finally got a PM sent...I hope.

Thanks for the offer.

If you have something you need worked on, let me know. Maybe I can help.

For those interested in CEP - the next version of AATranslator will write AA1.5 sessions and will have much improved reading of all CEP (after CEP1.0) & AA session formats.
