Re: Progress?

Hi Florian,

At the moment, yes, but it seems to me that having a reference level for 
monitoring is only one part of the story. Bob and other AES members will 
no doubt be working in acoustically tuned mastering rooms, but I'd 
hazard a guess that most Jamin users don't have that luxury.

There are now a number of self-calibrating monitors on the market that 
use a measurement microphone and on-board digital EQ to correct bumps 
and dips in the frequency response of the room they are placed in. 
However these monitors are like to remain expensive, and have interfaces 
controlled by proprietary software (uggh!). The extra hardware in these 
monitors is only there to do a job that a commodity PC could do, and we 
already have a finely-grained EQ plugin at the heart of Jamin.

So I figure if you're using a microphone and some kind of SPL meter to 
set your reference monitoring level, you might as well analyse the 
frequency response of the room while you're there. Sort of like doing an 
impulse response in reverse - instead of sampling an effect you want 
(live room reverb) you sample an effect you don't want (mastering room 
non-linearity) and correct for it.

This could be in a 'monitor output' section of Jamin or it could be in a 
standalone Jack application. Obviously you don't want your room 
correcting EQ to be applied to the mastered audio, only the output which 
goes to your monitoring system.

Cheers!

Daniel
