Hi there,
Last weekend I played with my speakers and my pc to correct the room.
Sound was very booming with several peaks at, 110hz, 220hz and others (I'm speaking of peaks/deeps in the order of 12dbs!I don't know if this is common), i use no sub, but just a couple of Edifier R1900TII, supposed to have a good flat response.
By now i decided to correct just the basses until 600hz, because i used a good microphone (Samson SAQ7 Cardioid Dynamic Microphone), but not a measurement one (waiting for one to be shipped)
What i did was to place the mic in the listening position and keep playing a continuos white noise with audacity and analyzing the responce with REW set to smoothing=1/6 and a large window.
Initially i tried to use rew itself to generate the equalizer settings, but the results was very poor to my ears.
So i decided to do things manually, being on linux, by using:
https://lsp-plug.in/?page=manuals§ion=para_equalizer_x16_stereo , and keep changing the equalizer until i saw the rew analysis as flat as possible.
The good thing of software equalizer i used is that it supports several Bell filter modes (RLC,BWC,LRX,APO,BT,MT,DR) that REW doesn't support and that i found absolutely necessary to correct the signal.
I've to say that my edifier r1900tii never sounded so well, and, to my surprise, even changing the listening position alot, produced a better sound than before.
Now I can hear some resonance in the 1k..2k range never heard before, but maybe it is just because the sound was so bad before that now i can focus on less imoprtant "details", i didn't touched that range because i plan to do that work when the berhinger ecm8000 arrives.
I didn't expected to be able to do such improvements with a mic that is targeted to human voice, nor, as said, i expected that i can freely walk in the room and have good sounding music.
Is because i didn't go the convolution way that the listening position is wider?
Are there hidden problems i not yet faced with the approach i used?
Thanks!
