Here for the gear
 

Ok well.
This is a new completely empirical non scientific approach to help me visualize the problems in my room.

You need to stop me!

Here is what I did.

- I took 8 relevant measurements in my room:
1) Bass Rig measured from the bass player's ears position.
2) Bass Rig measured from the drummer's ears position.
3) Bass Rig measured from the guitar player's ears position.
4) Bass Rig measured from the center of the room.
5) Bass Rig in the kick drum position measured from the bass player's ears position.
6) Bass Rig in the kick drum position measured from the drummer's ears position.
7) Bass Rig in the kick drum position measured from the guitar player's ears position.
8) Bass Rig in the kick drum position measured from the center of the room.

- Calculated the average SPL per octave for each measurement.
- Calculated the absolute difference of the measurement to Its own averages.
- Multiply each abs diff curve by a "weghting factor" to give more importance to some measurements than others. (all factors add up to one).
- Add all curves.

This should give a graphical representation of the frecuencies that are showing more variance across the important points of sound source and listeners that are going to be tipically used in a rehearsal.

Some of the most problematic frecuencies showed by this approach are coincident with the frecuencies where I have the larger delay times.

Could I say that those are the ones to atack first?
