    If you boost something enough, whatever noise floor is there will come up. You can’t just boost level indefinitely without consequences. 

     

    The answer is a bit tricky.  It depends where in the circuit you are when boosting as to how much the noise floor will increase.  It is all about gain structure.  If you increase the signal as a whole then the noise floor comes up by your increased amount.  But with tone creating as with a synth is you “rescale” the forming signal with reference to gain structure there will be very little to no increase to the noise floor.

    Hi dBoomer,

     

    Normally I would agree with you, but to get the sound I wanted, I did some massive, massive cuts with the onboard Roland XV-3080 parametric EQ and it really sucked the overall gain out. I then had to dial some other frequencies out with Fabfilter post-recording. It might not have been 15-20 dB of overall boost, but it was a lot … Certainly more than 10 dB.

     

    The most common answer to that track is “find a different sound”, but Boy, I’ve spent a lot of time looking for a substitute and something about that specific XV EP (coupled with the right cuts) just works.

    OK, but how is treating your electric service gonna fix your noisy synth problem? ;)

    If I’m really specific and honest, I wrote/recorded a simple electric piano piece that uses my Roland XV-3080. I had to cut the crap out of certain frequencies to get the sound I wanted, and I had to boost the overall level a large amount (15-20 dB) to get to a listenable mastering level. In doing so it revealed a lot of noise, and while I think it might just be a noisy module or sample, some suggested it was electrical in nature. 

     

    If you had to boost 15-20dB you have a major gain structure issue and not interference in your ac lines.  Looks like you are gonna spend a lot of bucks correcting the wrong problem.  You need to improve your dynamic range and not boost your levels which automatically boosts your noise levels.

  4. Do you have a particular problem you are trying to solve?  Otherwise you are probably just throwing away money.  In my experience, using power conditioners that cost less than $1K are generally useless and really only show improvements to video gear and not audio gear.

     

    Most all gear produced in the last 10-15 years uses switch mode power supplies.  This style supply is pretty much self regulating and is susceptible to problems when connected to power conditioners.  You may be creating a problem you don’t currently have.  YMMV. 

  5. I would think you need to take into consideration whether you are hearing from an engineer is the “stereophile” business or in the “live sound” business as I’m guessing they have different points of view going in.

     

    There is no doubt that almost without exception transducers change after some time has been spent flexing their surrounds.  The question is does that make a discernible  difference to a listener?  And does that even matter?  Because your hearing perception changes quickly with ever one degree of difference in ambient temperature and humidity.

    Without doing double blind testing you are likely fooling yourself.  I have fooled myself many times.   So if you wanna step that game up find and load yourself an “ABX tester app”

     

    Basically it lets you audition A or B as many times as you want.  Then it randomly plays one or the other and calls it X and asks you which sample that is. At that point if you can repeatedly pick the right answer 10 times in a row you can hear a difference.

    Yet I can't help but wonder if measurements mean everything. I consulted to a software company that modeled a channel strip plug-in. They were sure they had nailed the sound, it measured the exact same frequency response, phase response, harmonic distortion, you name it. Yet their beta testers kept insisting it was different.

     

    When the company injected a tiny bit of hiss, the testers said they had finally gotten it right :) Apparently they associated the virtually subliminal amount of hiss as part of "the sound." Bear in mind they hadn't been told hiss had been added, they were just told it was a new build.

     

    Now, I'm not a super golden-ears type by any means, who hears sonic differences depending on the knobs you use. But, I do think components can measure the same yet have a different sonic character. You'd know more about this than I do, but if a company invented a silk dome tweeter, a ribbon tweeter, and was able to have them match exactly in terms of frequency response, THD, etc., would they sound exactly the same, or would they have subtly different "characters"?

     

    I don't know, I'm just asking questions LOL :)


    i think our statements are opposites. Mine is - just because you can measure differences doesn’t mean you can hear them. And your example is even though they measure the same, they sound different.  To which I would simply add, they didn’t measure the thing that made the sonic difference even though many other factors measured the same.

     

    So with respect to “breaking in making an audible difference” …remember that in general you need about a 3dB difference for very  trained listeners to hear a difference.  That would mean something after break-in would have to double or half in the process. Typically what “breaks in” is the surround/compliance.  Doubling would be a pretty big change for simply breaking in.  So certainly the designers would be aware of this. I can’t imagine a releasing a transducer that I knew was gonna double or half.

  8. I can say with certainty that speaker components do undergo some changes after break-in having measuring a few dozen. But it should be a very small amount.  Measurable yes but actually perceiving an audible difference, not so much. In my days as a designer, if I had put out a product that you could hear much of a difference, I would have considered that product to be defective. Day to day changes in temperature or humidity I would expect to be making a bigger difference in perception.
     

    Changes in mojo?  Well, whatever makes you happy ;) w

  9. Well then my vote is for a more heavy handed approach to moderating.  Tolerance and understanding of how others think and feel is in extremely short supply on internet forums.  
     

    The way I see it, there are about 10 guys who regularly post here that we all know their political opinions. I am guilty of posting some of my opinions a few times. But for that group of frequent flyers keep bringing up the same comments over and over and over. To those guys- we heard you the 47th time you said it.  How about saying something else or not saying anything.

  10. Sad to hear the news. I first met Mike about 20 years ago when he scored me some tickets to NAMM as I was transitioning between music store owner and music manufacturing. We met up at every NAMM since. He could always give me a head start there as he had a way of finding the hidden gems there. It was always a pleasure and I will miss him.

    But if you think that 6500 died a few days or weeks later as coincidence........?? from an unapproved FDA "vaccine" .

     

    You seem to be missing the point. These deaths simply occurred after receiving the vaccine and include those who were hit by a bus or choked on chicken bones and every other single reason under the sun. Nowhere does it say they died because of the vaccine but you seem to be reading that into it. You have to read more than the headline.

     

     

    Btw ⦠the vaccine is not 'unapproved'. It is simply 'not approved'. Big difference.

    The only medical experts we are allowed to listen to are the ones who agree with the government. I'm skeptical when other experts are denied a voice.

     

     

    PG ⦠your analytical skills need a touch up. It seems you consistently only consider 'evidence' that supports your thoughts and reject any that do not. Classic confirmation bias.

     

    Who has been denied a voice and where? That simply is not true. They can get on a soapbox and stand and say anything they want on any street corner. The fact that some people won"t give them a soapbox does not deny them the ability to say something. What is true is that some of these other experts opinions in peer review are overwhelmingly rejected. There will always be 'experts' with opinions that get tossed out. But they are outliers and on the far end of the bell curve by definition by their peers
