Audessey versus using a SPL meter

Recommended Posts

I went over to my FIL's today and we calibrated his system using my new SPL Meter.

 

Question, would you trust using Audessey or the SPL Meter?

 

Cheers

To answer this, I think we need to understand a couple of things:

i) what do you call calibrating; and 

ii) what is your new SPL Meter and are you using any software with it?

 

Audyssey does several things,  Sets relative volume levels, sets individual delays for each speaker  and also applies room correction/Eq'ing.  Bad results can be had by not being careful when undertaking an Audyssey Cal.  Excellent results can also be achieved.  There is an excellent guide somewhere for this, though I don't recall at the moment where it is.

 

If you new SPL is just a $20 Ratshack jobbie, then it will just measure db's and not any of the other things that Audyssey takes into account.  If you new SPL is a UMIK1 or similar and you are using it with the likes fo REW, then you can achieve a far bit more, but you still can not easily apply equalisation (that I recall).

 

If just setting vol levels, I would rate the order as UMIK with REW then Audyssey, then bottom of the pile a Ratshak or phone meter.  Others experience may be different. 

 

If you want to get real serious, explore UMIK-1 mics, REW and also using DIRAC with a MiniDSP 88A.  This is however not a simple or cheap exercise.  If I find the link for the Audyssey cal info, I will post it here.

I always use a good, calibrated mic and REW or similar. Audessy is a PHD* solution for the average consumer and works well for that. A typical SPL meter won't be as good.

I’ve never had an issue with the levels produced by Audessey.

Cheers guys, I bought the SPL from here: https://www.jaycar.com.au/compact-digital-sound-level-meter/p/QM1589

 

His system has Audessey xt32 mine only xt as it is an older Denon.

 

I havent used the SPL on my system as yet however with his we ran the room correction but then used the SPL to set the channel levels.

 

I wasn't sure to just trust the room correction and not adjust anything or use just the SPL and manually change everything or use both.

I always verify Audyssey's calibration using REW and a calibrated mic - and adjust levels accordingly, and I (and a few others on AVS) have found Audyssey sets speakers 2-3dB hot (so around 77-78dB) and subs usually a dB or so low. I have personally checked this with 3 different AVRs (1x XT, 2x XT32) and 5 different Audyssey Mics (purchased some new ones from Aus distributor and eBay) and using 3 different calibrated mics with REW (1x Dayton , 1x miniDSP umik-1, 1x CSL calibrated umik-1)

 

Probably not necessary in the grand scheme of things, but I just like to know that when I'm watching a movie at -5MV  that I'm actually -5dB from Reference Level.

as long as you have followed the guide posted above to the letter you will likely all is well. it is usually only when you dont follow the guide decide to go off beaten track you tend to get caught out. I have used audyssey over multiple AVRS and processors over some 15 years.  THE main issue with audyssey is the mic used. in the case with the thrown in one its quite likely 1-3 db out ! 

 

however is that a big deal for most not as long as consistent. 

 

XT is basic and in capability. it will still calibrate the same just lacks the sophistication and capability with dual subs. I would go with the flow and see end result. it should get you pretty close :) 

 

things like sub level ... audyssey expect you will "salt to taste" ie adjust a bit up down to preference. keep in mind audyssey is just setup and EQ its trying to make best of the situation. its far more important to get setup and room right in the first place. measurement then is no big deal and eq needed less rather than more.

For what it is worth, when I was running Audyssey, I would normally add about 5dB to the sub(s).  Also, used DynEq, to compensate when running at lower dB levels.

dynamic EQ is an absolute must and audyssey expects you to use for listening below reference. it will do its own boosting of freq to make sure EQ is dynamically adjusted for  volume vs freq. whether OPs FIL AVR has dynamic eq is another thing.

Just to open a can of worms - in some capable AVRs you can turn the 'Midrange compensation' on or off via the Audyssey app.

What is this setting for and should you leave it on or off?

it is one of best things can do with audyssey. its the BBC dip... they have it in by default and if running pro or very latest app version you can remove the dip

I have always preferred to remove the dip...

Thanks ... do you actually notice a difference with it turned off? I'm struggling to hear any difference on or off.

perhaps with your speakers there is no real difference anywise :)

Audyssey can sometimes get the channel levels wrong for various complicated reasons (nothing to do with it's microphone being "not accurate enough") .... so it can be good to give it a check.

With my SPL Meter it has C weighting, slow etc then has a setting for low which is 30 - 100db and a high setting which is 60 - 130db. I have tried both and there is a difference of about 2db when using high v low etc

 

Anyone know which setting should be used?

 

Cheers

      Marantz SR6012 vs Denon 4500
       
      Looking forward to upgrade my AVR.
      Between above two  AVR which has good hardware configuration?
       
      Currently using Denon 520BT for 3 years. Happy with the Sound signature.
       
      Thank you

      Hello everyone, 
      Good day . I am new to stereonet. Looking for some recommendations for my stereo(40%)/HT setup(60%).
       
      Current setup:
      Klipsch RP 260F (L-R), Klipsch 450C (Centre), Klipsch RP250S(surround)
       
      Sub : SVS PB2000
      AVR : Denon X 520BT
      Connected to TV.
       
      Looking to upgrade my AVR and add power amplifier. Looking for some recommendations.
       
      As klipsch are bright sounding speakers need to pair with Warm sounding amplifiers like Denon/Marantz
       
      I am looking to invest in something which will future proof for next 5 years at least.
       
      Any recommendations will be helpful. I am new to this world of amplifiers and sound. Please excuse for newbie mistakes/questions.
       
      how good is ATI power amplifier?
       
      Thank you.

      Item Condition: new
      Reason for selling: nlr
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
       
      for 3100$ good luck beating this. Smooth silky vocals with good bass control. 
       
      the dac isn't too bad, bit this unit really shines with vinyl .. the only issue with the dac is it may lack overall dynamics.  And is a touch forward. But!! That's  comparing it to seperate  dacs over 6 grand. Hence why i say for 3k this will be very hard to beat 
       
      i purchased brand new with 2 years warranty .
       
      only 15 hours on unit 
       
      (**I'm only selling this unit because my accuphase poweramp is not selling. If someone wants to bid for the accuphase then i can keep this denon 😁😁😀**)

      Item: Denon AVC-X8500B
      Location: Perth
      Price: $4000 $3800 + shipping
      Item Condition: Excellent (1.5 years old – but has been boxed for last 5 months)
      Reason for selling: Moved house with no room for theatre ☹
      Payment Method: Pickup - Cash, Paypal, Bank Transfer
      Extra Info
       
      Denon’s flagship AVR with 13.2 channels. Allows for a very flexible arrangement with 9.2.4, 7.2.6 ATMOS, DTS-X or Auro layouts.
       
      The 13 channels are fully amplified, so an external amp is not required to fully use all channels.
       
      Comes with all documents and accessories. Have original box, so shipping is an option (fyi this thing is not light).
       
      If you search my name, you’ll see details of my previous system(s) so know that I am an enthusiast. Rest assured when I say this is a quality and very capable product. I was extremely happy with the Denon. If I still had my system, I would have happily kept it until it died (with the only reason to change out being going to a higher channel count).
