If so - you will have to go back to the Studiolive Tab and call up the VSL screen and go to the graphic screen - make changes and then go back and rerun the analyzer. This will be a pain to do.


This is exactly what I decided to do to analyse my studio. It is clumsy but the end result is more accurate.

I think the room analysis wizard has been poorly implemented. I makes much more sense to engage the 31 band graphic to do this job. If it were over-layed on the curve it could be adjusted in real time. This is how it is done in the Real Time Analysis so why not in the room analysis?

Actually Michael, using the 31 band EQ will have a worse affect than the parametric.

Because each band has a set frequency and Q, using this will actually make it more difficult to shape the response smoothly. Instead you'll probably end up with small peaks or dips instead a smooth curve.

The parametric EQ allows you do make the changes you need to make exactly how you need to make them without destroying the sound.

You will find that in much bigger setups 31 band eqs and generally used for foldback speakers only. Everything else (in ears, FOH) they will try to use fully parametric.

If you look at it from the point of view that each and every one of those EQ bands is a tuned tank circuit that delays, causes phase differentials, and generally affects the relationship with the unaffected signal...each one does this differently...so, multiply this by 31 bands and you can REALLY screw up the sound with an EQ, this happens with PEQ's also but with a PEQ, you can get to the exact frequency, and adjust the width of the filter to only affect the frequencies that are necessary to accomplish the goal. With Geq's you can use one band to affect very Little of the spectrum or anything up to the whole frequency range,

This would require multiple Geq bands and even if you need to make a small cut to a very narrow frequency group, you wold likely need to use 2 or more Geq bands because it seems the problems are NEVER on the ISO center frequencies. If you doubt this, do a SMAART of the room and get the trace as flat as you can, not worrying about the small peaks and dips... now, take that same curve and try and duplicate it with the GEQ....now play something like Steely Dan or something that your familiar with and then turn the GEQ off and see what it sounds like, do the same with the Peq... It WILL be illuminating!
