Room Target Curves - then, now, and options to try...

Be it resolved that there is no such thing as achieving sonic perfection - technically at least based on objective ideals, but "perfect" can also be a subjective state of mind.

In domestic homes, we're simply not going to be able to achieve near-perfect rooms. Likewise, no sound system will be absolutely transparent although the digital electronics side will get much closer to "perfect" than analogue playback and loudspeakers. Furthermore, beyond what we can say about our domestic playback systems, despite all the care and detail-orientedness put into a recording studio, they're not identical even if they followed published standards (like ITU-R BS.1116, or EBU Tech 3276), and besides, is there ever such a thing as a perfectly engineered recording? Or a perfect performance from our favorite artists for that matter?

While perfection might be out of reach, let's not turn away from the pursuit of what is reasonably accurate which is something we can all do to some extent whether it's choosing better-engineered gear, working on small room acoustics, or using DSP to improve frequency response and/or time-domain performance at our listening position. Regarding the specifics of DSP room correction, let me refer you to previous articles covering various methods here, here, here, here, and here.

The intent of this post is to focus on the topic of Room Target Curves which we define and apply when doing EQ and DSP correction. Let's explore a little history, what they are, what they look like and considerations for what to try at home.

SUMMER MUSINGS: True audiophile aspirations; recent events in the audiophile culture - end of Atkinson's Stereophile measurements, YouTube influencer legal drama.

Through my years as an audiophile, I've come across articles in magazines and online talking about hobbyist "aspirations". At audio shows, and seemingly each new issue of magazine we read, we're introduced to the latest and greatest piece or gear, the next "must have" item to consider in this never-ending path of upgrade to satisfy luxury consumeristic appetites.

Given that it's "Summer Musings" season, let's take some time to think about what I think is the most important aspirational item in all of the audiophile hobby - your room. And since in the last month there have been other events happening in audio news, let's also talk about the fact that John Atkinson has retired from doing measurements for Stereophile magazine, and the interesting legal drama around the case of an "influencer" (Michael Gefteas/The Greek Audio Geek) and social media.

SUMMER MUSINGS: "Final" ceiling absorption 😉. AI-assisted summary of Floyd Toole's thoughts on early reflections treatment & discussion on this.

Hey guys and gals, it's July and thus time to enjoy some summer jams, BBQ, and family time ahead. And of course getting into the "Summer Musings" season here on the blog!

Let's "shoot the breeze" and talk about a couple of things in this post related to discussions over the last while with room treatments and acoustics you might want to consider for your own space.

First, as you can see in the picture above, despite the self-proclaimed statement that I was "done", I just had one more little addition to add. I cleaned up and optimized my seating area a little and realized that the rear ceiling panel wasn't exactly overhead. So I added an extra 2' x 4' x 0.8" PET panel immediately overhead above the main listening position. [I also spent some time optimizing the height channels and DSP recalibration along the way.]
