Modeling

 

Having all of your audio and FX in the digital domain has huge advantages, as we have seen. One of the great new technologies available using digital FX is modeling. Modeling technology takes a known source and "models" the sound characteristics of one or more usually very expensive sound processors or devices.

 

The three most powerful modeling technologies available today are COSM* guitar amplifier modeling, COSM microphone modeling, and COSM speaker modeling.

 

Guitar modeling simulates the sound of very expensive guitar preamps, amplifiers and speaker systems using as an input a standard electric guitar.

 

Microphone modeling simulates the response of some very expensive large and small diaphragm condenser mics using as an input very inexpensive dynamic microphones.

 

Speaker modeling creates the listening experience you would have using a variety of expensive studio monitors or even TV speaker or a boom box from the same, inexpensive digital powered reference monitors**. Using just this one set of speakers you can hear how your mix would sound in a variety of listening environments. This is a great way to improve your mixing skills and make your music sound its best in a variety of settings. * COSM stands for Composite Object Sound Modeling, a proprietary technology from Roland Corporation. COSM is used to model a wide variety of expensive microphones, guitar amplifiers, and monitor speakers.]

 

** COSM speaker modeling uses the COSM modeling software in the VS-880EX or VS-1680 with the Roland DS-90 Digital Powered Reference Monitors to model a wide variety of speaker systems.

 

How Does Modeling Work?

 

Let's take a closer look at speaker modeling to understand how this revolutionary technology works. First of all, you need a "source" speaker system designed to work with the modeling. All of the sound reproduction characteristics of that speaker system is studied by the engineers and mapped out. Next, the same characteristics of the speakers being modeled are studied and also charted out. Then advanced DSP technology is used to adjust the output characteristics of the source speaker system to exactly match the output qualities and characteristics of the speakers being modeled.

 

 

The bottom line is that you can listen to your mixes as they would sound on a wide variety of very expensive and also some inexpensive, lower fidelity but very common speaker systems. Using Speaker Modeling, you can check your mixes and make sure they will sound great in many different listening environments just as they do in very expensive studios all over the world!

 

Modeling technology lets you save lots of money and still make world-class music.
