Hello, it's called "room" correction software. My understanding is the eq software's aim is to smooth out the added peaks and nulls due to the rooms dimensions/reflections and containment of sound waves (across the audible frequency). Also the same room eq software enables the user to eq the “final“ sound of the speaker and room as it enters our ears at the MLP. My question is, if you eq the speaker near field to optain the "desired frequency / sound" from a speaker, the room will still have an audible effect on what we hear at the MLP? Starting with the best possible speaker response is ideal but if the goal is to "correct" the speaker isn't there a danger of having all makes of Speaker design sound very much the same? If you used magic beans on many different speakers in an open space (to remove the room) then the eq would try to give each speaker the same audio frequency output. But that output would be smeared by the room acoustics before we hear it at the MLP. 🤔👍

Magic beans is measured at the near field location infront of the speaker and at the MLP then the delta between the 2 is perfected to achieved the desired output Every speaker is also made differently as well as the materials thatvare used give them each their own unique timber so will sound different regardless I suggest you go watch the video where Joe explains it to some other sound engineers then read his comments below

The term room correction is a misnomer because physical means are required to truly treat the room in order to correct it. The truth is the signal being sent to the speakers are being altered to account for the effects of the room. The EQ 'ed nearfield response will still be affected by the room response, but as I mentioned, Dr. Toole discusses how we are able to "listen through" the room reflections in the higher frequencies in order to focus on the direct sound from the speaker. Even if it were possible to EQ all speakers to perfectly flat, which is not true for many speakers, they would still sound different because they have different dispersion patterns and different off-axis response. Flat on-axis is just one aspect of the sound we hear. In response to your last 2 paragraphs, I think you would enjoy reading Floyd Toole's book on psychoacoustics. It will answer that. I touched on it earlier in my response as well as in the video. You don't just hear the combined sound of the direct sound and reflections. In higher frequencies, you hear 2 or more different sounds and can differentiate between direct and reflected.
