Hi folks, I'm going to jump right to heart of the question. See below *Background* section for further background and context.
In my research, I see two general approaches to taking room measurements in the context of a near-field room and speaker correction. And a few variations within:
1. Take measurements of all speakers at and around the main listening position. Use REW to produce EQ settings, export into text file and import into EQ software like Equalizer APO to apply corrections. . The eq settings consist of Freq, gain, and Q.
1 (variation). Take individual measurements of speakers (left and right). Use REW to produce EQ settings and export into text file. Import into EQ hardwares/software that supports individual L/R EQs.
2. Take individual measurements of speakers (left and right). Use REW to produce an Impulse response file for each speaker. Import those into a convolver plugin to apply corrections.
So my question is, what are the *practical* differences between these approaches? Why/when would I do one or the other? Is one more accurate? Does one allow you to do more equalization with less artifacts?
For example - one thing I understand about approach #2 is that your IR files must be generated for a specific sampling rate. And when listening back, you need to use the IR file for the sampling rate that is playing. This is a clear practical difference between approach #1 vs #2. What are some others?
** Background **
I've been digging into the measurement and EQ topics for a few weeks now. I'm not exactly a newbie - I did started working with REW many years ago to help set up the sub in my HT room. But much has changed so it took me a long time to weed through this all. For my recent measurements, I just used a mic I had on hand to get familiar with the software and process again. But my UMIK came today, so its time to get serious.
My goal this time around is to measure and correct the speakers in my "recording studio". So the primary goal is for a flat response for mixing music. However, I do find myself listening to more music on this system, so simply enjoying music playback is a goal as well. Some equipment/software currently in use ...
* Speakers - JBL 306mkII
* Sub - Tannoy TS10
* Interface - Behringer UMC404HD
* DAW - Reaper
* Music Playback - Foobar (no Roon or JRiver)
* Other software: Equalizer APO and many many plugins for Reaper
