In the application 'VU' meter, is there any way to increase the maximum DB, its currenty at 106db...
Either that or are there any other applicatinons that can exceed this?
Thank you
Craig

I don't know what is ment by linear though, The 2 options give very different outputs :S

The Decibel is a logarithmic unit, so the difference between 20 db and 60 db is way greater than only 3 times. I think by linear 60 db = 2 x 30 db. I hope you understand what I'm trying to say.

Because Linear mode doesn't measure decibels, if I understand it correctly. Decibels are logarithmic (I.E. see the post above mine), where as linear is just that - linear whatever-the-unit-for-that-is. So 200 in linear does not equal 106 decibels. Simply put, 106 decibels (whatever you chose to number the linear scale at) is where the microphone stops distinguishing the volume.

I understand what DB's are in volume of sound but i don't under staind the 2/3x 30db?
EDIT: okay i did some reading into DB's and all the different types, turns out i really have no idea on the term.
The only thing i really understand is that 100db (in acoustic terms) is quite loud, but i have no idea about the inn's and outs...

I was giving an example. I will give another one: A whisper has around 20db, a washing machine which is way louder than a whisper, has around 70db. The washing machine sound is more than 4 times louder than a whisper because the decibel scale is logarithmic, which means that the db scale is not liniar like meters. For instance, 2 meters + 3 meters = 5 meters, 40 db + 40 db are less than 80 db. Maybe the liniar mode of the app converts the logarithmic scale to a liniar one, where 40 db + 40 db equals 80 db, not less.

So @ 1 meter(which is normally what sound is recorded at) what is the more accurate, DB or linear?

I think both have the same accuracy, the difference is the measurement unit. Choose the one you like more. Linear would have more sense than db, but db is usually used to measure sound.

dB is a lot more logical for sound since our ears are logaritmic.
-However, a way to use an external mic, and calibrate the program to that mic would be nice
