• Perceived Acoustic Power Calibration: Sonarworks calibrates your speakers based on Perceived Acoustic Power measurements which is the closest representation to how humans hear sound.
• High resolution phase linear calibration plug-in allows you to set filter resolution up to 4 000 coefficients for razor-sharp calibration, while ensuring the phase response of the sound is not distorted. To maintain phase linearity plug-in introduces signal latency. The plug-in is intended for mixing and mastering applications and is not recommended for live monitoring due to latency. Sonarworks 2.2 plug-in supports audio sample rate up to 192 000 Hz.
• Up to 30 measurement points: Sonarworks 2.2 allows you to make up to 30 measurement points in each measurement session for best-in-class result accuracy.
• Microphone location detection technology: Sonarworks unique patent-pending technology automatically detects the test microphone’s location during measurements enabling Sonarworks to deliver the best possible result in any environment.

 
Sonarworks is a recording studio software development start-up specializing in acoustic calibration and DAW plug-ins. The company made its debut in the music industry by pioneering a plug-in based headphone calibration that makes them suitable for mixing and mastering.
 
The company is currently offering a free and fully functional 21-day software trial of the Sonarworks Reference 3 software at Free trial of Speaker and Headphone Calibration Software | Sonarworks. A measurement microphone is required to use the software. Sonarworks offers a bundled version with a custom calibrated measurement microphone for 269.00 EUR / 345.00 USD. A download only license is currently 229.00 EUR / 299.00 USD. Both bundles contain one measurement software license and two plug-in licences.

I've been mixing a few projects & have to say I prefer this over ARC, more natural listening. To me ARC has a boxy, narrow stereo image, phasey vibe. This is like mixing in hi-fi, actually enjoy the sound coming out my speakers compared to ARC.

My mixes came together quicker too. I'll have to test this out in my other studio next month but I may go for the intro offer.

If you have ARC or looking for RC software I'd check it out. 21 day demo, no restrictions. Easy set-up, no plum bobs or floor charts needed.

Good to hear that you liked the sound, Carl!
 
When we did our beta testing round about four or five testers did direct comparisons with ARC2 and their impressions match with yours.
 
One thing we have and so far no other calibration software offers is headphone calibration. We can ensure that you will have the same reference quality sound on all of your listening devices. It's easier to try out actually - we have average calibration curves for these headphones - 
 

• AKG K141 MKII
• AKG K701
• AKG K712 Pro
• Sennheiser HD598
• Sennheiser HD600
• Sennheiser HD650
• Sony MDR-7506
• Superlux HD681

Sign up for plug-in trial and you will have everything to try it out.

There aren't many details on the web page so I have some questions about the speaker calibrator:
 
1. Does it let you store multiple settings in case you have several sets of speakers?
2. Can it be installed on multiple computers in case you want to calibrate different rooms?
3. Does it use ILOK or other extraneous devices?
4. Since the demo doesn't include the calibrated microphone, how does it work?
 

1. Every measurement session generates a separate calibration file. Store as many as you like for different speakers, rooms or setups.
2. The basic bundle includes 1 measurement software licence and 2 DAW plug-in licences. Therefore you can use one computer for calibration and then utilize the calibration on two computers.
3. Currently no and most of the guys in the team are skeptical about it. We'd rather use the effort and funds to improve our software.
4. You can download the trial if you have access to measurement microphone, preferably calibrated one. Otherwise - you will need to buy our Trial package which includes a measurement microphone with 30 and 0 degree calibration curves done by us in an anechoic chamber against an Earthworks mic. If you are still unsure after the 21 day trial period, send the mic back to us and we'll refund the purchase.

Thanks for the answers!

I wonder if the stock ARC microphone would work with the trial or if you actually need a calibration file for the software to read/use?
 
I just signed up for the headphone trial and plan to use the average AKG K701 cal file. I am interested in this as it looks like the latency is low enough that you could possibly Track using it also.

That's what I used (or use a similar condenser microphone)

Thanks Carl
 
I just tried out the headphone correction software using the AKG K701 and stock correction file. I am impressed enough that I am going to bite on it. Maybe just my initial perception but it sounded like it opened things up and I seem to hear the sound field a bit better. Hope the above discount code works on it and a second license...

That's interesting you like the phone correction SW.
I was going to demo that but they don't have the calibration file for phones I'm using here.
 
I could use an inexpensive spare set, I'm almost tempted to get the software+Superlux HD681 to check it out.
