    Metal Music and Hi-Fi?

    Make sure you don't get speakers which will be over-driven (if, perhaps you like to listen loud, or to music with lots of bass). Some sort of EQ or tone controls will be very helpful .... allowing you dial up/down, the bass/treble ..... to tame those recordings which have been made a too agressive tilt. The rules aren't different from any other genre ..... except it might mean you will have lots of SPL, bass, or want to adjust recordings

    Fetch TV Mighty question

    I thought it was juts $1, one time. Are they actually charging me $1 every year!??!?!?
  3. No, there'll be no major penalty. The DAC will receive audio from the scale which has been oversampled to ~384khz ....and then your DAC would do no more oversampling.

    One sub or two.

    Indeed .... there have been a few paper published over the years which have caused people to think there is something magic about the number of subwoofers, or their positioning (eg. corners, or mid-points of walls, etc.) These papers cause people to think in terms of a "special arrangement of subwoofers" ... but really, they are not very far different/better to random. It helps to keep each woofer, different dimensions from other woofers, the listener, and the boundaries.... ie. as random as possible.

    Measuring and EQ are not simple.... and EQ is very powerful .... so it is not hard to make a good system be terrible. That being said, rulers and measuring tapes can be misread too .... but when people are building a bridge over a river, they don't just guess how far it is to the other side, or how high the bridge is / should be.

    Listening will tell you whether or not you like a specific setup, or not...... It won't tell you anything else. You won't know the cause of what you are listening to (eg. too many subwoofers, or poorly setup?). You should expect that adding additional bass sources will lower distortion due to not moving the woofers as much for the same SPL .... and smooths the frequency response due to the acoustic modal behaviour of a room (ie. the problem is that not enough room modes are excited). Both of these things are usually a problem that needs to be solved, but not necessarily.

    Sound Proofing...When do you have enough?

    Exactly. The spectrum of his noise floor could be substantially different from this. The A weight is good for showing you a single number for what noise you will be sensitive to..... it might not be appropriate for other versions of this sort of question (like how much dynamic range do you have in your system, etc.) .... where you might want to not exclude any data, ie. look at a whole chart. Yes, I'm quite well aware of all of this....
  8. I talk about EQ all the time on this forum....

    Really bad static/noise problems

    Yes, Toslink is a specific form of optical cable and connectors .... which would typically carry SPDIF formatted digital audio. SPDIF audio can also be carried over an electrical connection, but there are no super-formal standards for this cable. Typically you would use a coaxial cable .... and either RCA, BNC, or XLR plugs. Sometimes called a "SPDIF audio cable", or "digital audio cable" .... but really, it is "coaxial cable".

    Really bad static/noise problems

    Yes, it's a "coaxial cable". Cheap plastic cables have problems, which a better medium (plastic, or glass, both could be better) solves. "Glass being universally better than plastic" is an audiophile myth. In some respects one could argue that plastic is much better ..... but.

    Sound Proofing...When do you have enough?

    Not really. Yes.... A-weighting is more representative of how we hear noise.... but otherwise, it's not quite this simple. You have no way to know this for sure, without knowing the spectrum of his noise floor.

    Sound Proofing...When do you have enough?

    ... but this is plenty low for a playback system, yeah?!?

    Sound Proofing...When do you have enough?

    Nah.... Just as much as you "need". What I am saying is don't fall into the trap of not defining the problem well, and then just saying "Arg, I'm not sure if there will be enough soundproofing .... i'll just put in absolute shitloads to make sure it's not a problem". Definitely. You can achieve the right level of sound proofing, while still having good sound in the room ...... but you don't usually get there by putting in a concrete box (it sounded like that was being proposed), or need to do that.
  14. The whitepaper says ~600ms, and ~100ms in video mode.

    How quiet is your background?

    It isnn't quite so simple and it depends on what question you are trying to answer. If you question is "how audible it this noise floor" .... then an A or (preferably) ITU weighting, will focus on the frequency range which is most audible.... but then using a long windowed "average" type representation of the background noise (even with an A or ITU weighting) doesn't answer that question well, as what will be "most audible", is any very short term peaks (eg. a bird chirping, or door slamming, or whatever) ... which won't be represented in the number. What we are more likely concerned about, is how music is reproduced - which means we won't hear the background noise ..... we will hear the dynamic range. If you want to be able to see what the dynamic range is at each frequency, then an unweighted chart, will show that. In short, it depends very much on the specific question we are trying to answer, as to how you should modify (if at all) the data.
