Hi! Inguz, thanks again for your efforts - and all for free! I love open source! I hope my small efforts can contribute in some way to the improvement of your plugin.
I got the revised plugin today and it certainly works well with SoftSqueeze, so I have now re-retired my SqueezeBox (I'll find some use for that one eventually). The sound quality improved marginally, probably due to the better transport (Lynx Two vs. SqueezeBox), but not a lot. The main problem is still there. I've done some more listening and the way I would describe the sound is: ------------------------ Bass - boomy (flabby, loose), where it used to be warm, distinct, very precise, very low. My loudspeakers are Quad 909's (electrostats) + one Rel Stadium I subwoofer. The sub is connected to both power amplifier outputs and I suppose mixes the signal somehow. I've set the sub to kick in at almost the lowest frequency possible, to avoid too much interference with the Quads. I know the Quads are supposed to be full range, but I still found that adding the sub improves the bass so I stubbornly keep it for now. Not sure whether this has something to do with the funny bass response after filtering. One suspiscion: Maybe the mic, the ECM8000 is unreliable at very low frequencies. Looking at the recorded wavefile, there is very low amplitude in the low end of the spectrum and I'm not totally convinced that this is the truth. The normal bass response is very deep (maybe due to the sub) and precise. If the microphone gets this wrong, then of course the filter will try to "enhance" the bass and it will go all boomy? ------------------------ Midrange - not sure. ------------------------ Treble - "cut off" maybe. It's the same sort of difference as when comparing a normal CD to a Super Audio (SACD) recording. The SACD sound is often described as "airy", "wider", "opened up" etc - all very loose terms, but I agree. I still don't bother much with SACD's. The difference is there, but compared to an upsampled CD, it's not enough to be worth the hassle (I would prefer to rip SACD's and play them from the hard disk but due to SoftSqueeze issues that cannot be done, so listening to a SACD means actually getting my butt out of the chair to put a plastic disk into the transport...almost forgot how to do that...). The correction filter adds the same sort of difference (downwards) only many times the size, so much that it gets very audible. This is what I mean with "tunnel-sound". ------------------------ I've posted my measurement wavefiles to Inguz as I strongly suspect them to be funny (I did a few but they all look very similar). Looking at the recorded wavefile, the amplitude in the high end of the spectrum is much higher than the midrange so I suppose the filter tries to "correct" this by suppressing the high end. However, that makes the sound go "tunnelly" and it sounds all wrong. The reason I want room correction is not connected to the high or the low ends of the spectrum, those sound fine to me as they are. I have a few bad resonances in the midrange though which are really annoying and I can't use physical room correction here due to its negative WAF. -- CarlOtto ------------------------------------------------------------------------ CarlOtto's Profile: http://forums.slimdevices.com/member.php?userid=3581 View this thread: http://forums.slimdevices.com/showthread.php?t=26005 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/plugins
