Hi guys, This is about Room Resonance
I played a 20hz - 20khz logarithmic sine wav from https://www.audiocheck.net/testtones_sinesweep20-20k.php while holding a phone with an app (Spectroid) in front of my nose sitting where I sit when mixing. Not scientific by any means but interesting none the less to check the resonances in my 22 x 11 ft., music room.
My headphones (ATH-M40fs) and my speakers (JBL LSR308's) sound so drastically different I was curious what it would show.
I did my "test' twice and both times it showed a pretty big spike at 214hz , smaller ones at 132hz and 120hz and smaller ones yet at 47hz and 59hz.
47hz-83db
59hz-86db
120hz-89db
132hz-89db
214hz-80db
There was no way to dl or save the eq curve else I'd show it. Obviously my room has bass issues. My speakers have +/-2db hi and low filters which are set to zero. I don't see where that would help much...would it? I'm not sure what to do with the info..... I cannot afford to professionally "treat" the room.
Any thoughts?
