It is a wonderful tool to show you visually what your room response is to energy. Leave it running through all songs and music genres. You will begin to see consistency in how your room reacts to certain frequency ranges.
Thank you Dennis for another great video. Is it better to use great than a 1/3 octave RTA or is 1/3 sufficient? Also, when using REW or Dirac, how does one determine the appropriate Q of the Peak PEQ?
Leave the RTA running when you play music. As you change songs, the curve remains similar on each song. You will start to see patterns of movement. Divide the RTA at the 125 hz. mark. Study movement below 125 hz. and then above. Look for patterns of movement in the low end versus the mids and highs.
Hey Dennis, I was browsing your website and I saw your "All In One DIY Acoustic Treatment Build Plans Package" book, It looks interesting (pretty nice price), Does the bass absorber plan included in that package use the Activated Carbon Technology? . I don't live in the US, shipping costs for the carbon technology should not be cheap I think. Nice RTA video! Happy new year!!
Our carbon technology is the internal cabinent fill. We ship internationally from Los Angeles and London. For a quote send us your ship to information to info@acousticfields.com
Use your phone as an RTA mic? REALLY? Not to mention the open question of exactly HOW you're reproducing bass down to 30hz. Anyone who's measured subs outdoors knows they are anything but flat, especially below 50hz. At best, a sub will produce a broad peak somewhere around 60-80hz, which will drop off by at least -6db at its bandwidth limits. What you really want to do with an RTA (assuming you use a calibrated mic) is determine the best location for your subs that produces the most consistent broadband SPL all around the room. Forget making the RTA plot flat, in an actual room it will never happen.
We want to improve the actual room. Understanding how the room sees energy, will go along way to determine the treatment type required, how much surface area to cover and where to place it. Flat in palyback rooms is a goal. It can be achieved if that is your strategic goal.
Thank you for clearing that (RTA) up for me. Simple and to the point.
Its technical name is real time analyzer. However, it is really a resolution analyzer showing you frequency peaks and dips in response.
Thank you again sir ! And yes, every video helps. Happy New Year !
Happy new year!
Thanks Dennis. Happy New Year.
Happy new year!
Fantastic explanation, thanks for all!
Glad it was helpful!
Top Notch Video. Thank you sir.
Glad you enjoyed it
I'll try it, thanks!

If you have a 10db peak at the fundamental, does that mean a similar peak at the harmonic?
It would depend on the dimensions of your room at that frequency but as a general rule a fundamental peak is reflected in the harmonics.
Thank you Dennis for another great video. Is it better to use great than a 1/3 octave RTA or is 1/3 sufficient? Also, when using REW or Dirac, how does one determine the appropriate Q of the Peak PEQ?
1/3 is sufficient for general peaks and dip formations. Octave band Q is comparing each octave band movement with the others.
Wow spot on i did test with phone yesterday. Yes I see where my frequency aeas of concern! Love you bro!
