Well pink noise isn't music...so I'm not sure how one would use it other than to measure frequency response.
I suppose the point is that once you have designed your correction curve and implemented the filters then you could use pink noise to measure the corrected in-room frequency response. That's fine and doesn't require any gain matching. You can still create valid before/after response measurements at different overall gains. I thought the issue was about comparing music with/without RC (after you've got your correction curve built)? My point was that the music will inevitably sound louder when either flat or corrected, depending on the correction that is being applied. Usually RC will cut the bass quite deeply which makes the listener think the volume has been lowered (which it has - at their ear!) so to get back the same feeling of energy in the music you have to up the overall gain a bit to compensate. So, doing a A/B comparison is quite tough on the old brain. It really is just like comparing two loudspeakers with different sensitivities and frequency and dynamic responses. Everything changes - dynamics, timbres, stereo imaging...the lot!. For me the only way to evaluate RC and its curves is long term listening. Eventually I find that if I turn off the RC I really don't like the sound. Because of my setup, I have to bypass RC to use headphones. Occasionally I forget to turn it back on. Then I play the SB through speakers and wonder why it sounds "all bass and treble", harsh in the midrange with the image shifted to one side and a slightly "phasey" sound. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal... ...SB3+TACT+Altmann+MF DACXV3/Linn tri-amped Aktiv 5.1 system and some very expensive cables ;o) ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=38553 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
