    Do you hear with your ears or eyes?

    Cute squirrel!

    Why do movie makers get the HiFi so wrong?

    Totally off topic, but if you're expecting to see France Wales tonight, you'll be disappointed. First match is tomorrow.

    90s dance music and streaming platforms

    This 100%. I figured the "internet" would be archive of everything. But it's not.

    90s dance music and streaming platforms

    I think I've made a mistake. I put all my CDs in the attic figuring I'd make a move to streaming. So far I've been through Tidal/Qoboz/Spotify/Deezer But none of them carry a while subset of my music, that being late 90s club/dance/chill out. The entire "Back to mine" series which I collated...

    Master Thread: Are Measurements Everything or Nothing?

    An argument’s not the same as contradiction. An argument’s a collective series of statements to establish a definite proposition.

    Where does quantization noise come from.

    This is a good question - I think I intuitively thought it would somehow change the tonality slightly.

    Where does quantization noise come from.

    Yup - I think the thing is here, we know what the picture should look like, we don't actually know what the analogue signal "should" look like. (Or at least I don't look at amplitude/time line and read it like the matrix and know what it sounds like!) Thanks @staticV3 really appreciate your...

    Where does quantization noise come from.

    Which I guess then begs the question, how do we know if the signal contains noise or is in fact what it was supposed to sound like in the first place?!

    Where does quantization noise come from.

    OK I think the penny is dropping (albeit slowly!) here. And it's actually to do with how I envisage "noise" to look on a signal. To me, the yellow and green signal both look "clean" - they're both a nicely curved signal. One hits all the unquantized sample points, the other hits all the...

    Where does quantization noise come from.

    OK - I think this is the fundamental thing my head isn't getting... How does the yellow line already contain the noise - isn't the noise the red line?

    Where does quantization noise come from.

    Yup - appreciate all that. I'm not worried if it's audible or not, I'm talking theoretically here. I just don't understand why quantizing is creating "noise" when in my head it's just modifying the original signal. What is constructing the red noise line in Monty's chart? The only thing that...

    Where does quantization noise come from.

    Nope - still not making the connection! I understand the ADC quantizes from t1=4.43 to t1=4 - makes sense. The digital medium eg CD simply has this value. So the DAC then constructs the yellow line. Where is the red line? Why do we get any noise from this? The yellow line is just another...

    Where does quantization noise come from.

    OK - this may be due to lack of sleep or I'm just being incredibly stupid and missing the obvious - but I can't get my brain around where the noise comes from! So this is an image from the famous Monty video - and basically everything he says makes perfect sense. I appreciate the red line is...

    Help deciding on active floorstanders

    Yeah that's the problem, getting the balance between all those, when the options are very limited and wildly disparate in pricing... And a wife with expensive tastes

    Help deciding on active floorstanders

    Thanks all, doesn't sound like I'm missing anything, and Dynaudio is looking like it might win out. (As much as she likes the b&o, the saved cash can go into the mid life crisis Lambo fund ). I actually used to use Dynaudio in the car back in the days I used to compete in SQ - blast from the...
