`nico: o yeah i meant to tell you: wtf @ the buttons on your phone
they were like tough and not very clicky

everything in the middle is like, the mixing of the crossover components and both drivers complex impedances
what are you measuring with?
clio?
All loudspeaker measurements are performed independently at the National Research Council of Canada.
odam
yeah im pretty sure its them who have the badass chamber

that shit under 100Hz is the woofer response
thats like, the air suspension and mechanical suspension working against the mass of the driver
notice the speakers lowest resonant peak and the zero crossing are at the same freq
so you dont get rid of that
you can change it by changing your box and ports
around 40hz
no im saying you wont ever get rid of that, itll always be there to some degree
then the upwards slopes, 50-200 and 2K upwards, is inductance from the woofer and tweeter

no idea
i think phase/transient response is way more important than is normally considered
especially in low end response and mixing in the mid drivers
right but if you get freq response using 8th order filters, in a 3 way system
youre still going to have mad delay on one end of the spectrum
even if you manage to match the phase transistion perfectly and it blends well
whats coming out the woofer is going to behind the tweeter
go back to using less filter poles, better drivers with wider response
youd basically have to shoot all the current marketing people

at low frequency, you are adding up the energy from like one or a few values to make the new, log scaled value
at higher frequencies, you are adding up dozens of the values to make one
thats the behringer deq?
fuck as much as i dont want to be associated with anything behringer in any way ever at all
i kind of want one of those
a lot of people i respect technically have them
and the UI is pretty sweet
i think they have a xover too, same tech
less ui, more io
well no one likes flat speaker output
and its only going to be correct exactly where the sampling mic is
but yeah, supposedly americans, in blind tests, do not like flat speaker output at all

hmm no i dont think this is accurate way of describing, but i cant think of how to explain why
no it could be accurate with pink noise
for log scaled freq measurements it should be more accurate
okay say you do an FFT
that has 100Hz resolution
and your source is flat, white noise
so every 100Hz, you have the same amplitude
now you want to log convert the freq scale
so as you move upwards in frequency, you add up more and more of the amplitudes from the original FFT output

yeah
but with pink noise, you would have the same power between 10KHYz and 20KHz ad 100Hz and 200Hz
diff of 100Hz in one case, and 10,000Hz in the other
because you can split 10K by 100 more times than you can split 100 by 100
so there would be 100x the power in the last octave as between 100Hz and 200Hz
on a log scale (which is how we percieve audio amplitude and frequency), there should be equal power

nothing is random =(
in practice, pink noise is just filtered white noise
its usually filtered to get the power distribution right
then bandpassed and clipped for the application
test spec white/pink noise will have a consistent crest factor (rms vs peak ratio)

xapti: white noise has equal power distribution across the audio spectrum
so you have the same energy between 100hz and 200hz as you do between 10.1K and 10.2K
so in musical terms, almost all the energy is in the highest octaves
which is opposite of almost all actual source material (recorded music)
pink noise is log scaled
so you have the same amount of energy between 100Hz and 200Hz as between 10KHz and 20KHz
its per octave, instead of linear distribution
so instead of this high pitched spray, you get a jet engine rumble

also haha lulzsec
and haha @ anonymous sites all like WTF NO THE OTHER ANONYMOUS
meh, werqbye

`nico: omg hi
kbbl victorville wtf
`nico: i try and get resume to you tonight or tomorrow night
depending how long this trip lasts
