Establishing Project Studio Reference Monitoring Levels |

Establishing Project Studio Reference Monitoring Levels | Sound on Sound

In essence, what I’m talking about is establishing a reference listening level in the control room, to use as a reliable base from which to make aural decisions. The good news is that this is very simple to achieve, and doesn’t require any major investment in new equipment, although it’s certainly easier and more intuitive if you have a well‑designed monitor controller and a simple SPL meter.

Today was a good day to re-calibrate the studio monitors.

The mains are JBL LSR305, waveguide at ear level. On top of those are the M-Audio AV40 pair (serve well for typical people listening, no bottom to speak of).

The room is 3.2m wide, 4.4m long, 2.4m tall – I calculate a tad more than 34 cubic meters. The suggested reference level is 74 dB.

Fired up Logic with pink noise at -20 db, pushed the outputs to 0, measured on my trusty iPhone SPL meter (been using it for 4 years, I trust it).

I put a Behringer Monitor2USB monitor controller into the audio path about a year or so ago. Volume knob is top-dead-center – marked 50.

73.9 dB on the LSR 305, 71 dB on the AV40. The JBL volume is excellent. Nudged the AV40 volume knob a bit past TDC and got to 74 dB. OK.

All of this is run through IK Multimedia ARC 2 room correction software. I AudioHijack the system output and send it through the plugin. Separate settings for the AV40, JBL Main, and JBL Center. Center is a tighter pattern right in front of the monitor, with Main being measured 4 feet from the monitors in a pattern for 2-3 people listening.

Master audio output from the Mac is set to -13.5 dB which gets me music playing at about 74-76 dB all the time.

Right now I’m running the Apple Music playlist “Classic Acoustic” for some change of pace. Normally I will play my “Mix Test” playlist to test the world.

Trust me – the Trent Reznor track clearly “breaks” the room. The correction just can’t handle all the bass 😉 I follow that up with Pink Floyd which happily produces “master hiss” as remembered from the album and the CD.

It all just sounds GOOD.

Gain Staging In Your DAW Software

Gain Staging In Your DAW Software | Sound on Sound

On the face of it, gain staging couldn’t be simpler: you ensure that you feed an appropriate level from the first stage of your signal path to the next, and repeat this from the second stage to the third… and so on, all the way from your instruments, mics and preamps to the final stereo mix bus. By ‘appropriate’, I mean an ample level, which ensures a healthy signal-to-noise ratio (the difference between the wanted signal and the noise floor), while leaving enough headroom that you needn’t worry about whether the signal might be clipping.

Today is a good day to re-calibrate the studio monitors. I found the suggestion of setting DAW faders to about -6 dB to start in this article a long while back.

I set my Logic Pro X templates to have channels start there.
