easy, I do at least know that much about what squaring is ;)

It means that negative signals will count the same as positive ones.

Oh, did i say the interface was a web gui ? OS-agnostic ?

I bought a MOTU Ultralite AVB with my Asus n550jv with a double boot

the hanning envelope itself actually goes from 0 to "2" and not from 0 to
1, so I assume the compensation is done right there...

If I were in your situation, I’d stick with a Thinkpad. They are expensive, but
IMHO worth the price as they are rugged, reliable, and repairable. In general,
Linux distress run well on their hardware. Another good option is a Panasonic
Toughbook which are admittedly bulkier and expensive but yo

That's the problem: If the size of the analysis window is sufficiently
large compared to the frequency of a static sinusoid You can't really
expect any difference in the rms value
I do realize the windowing makes the result more accurate and stable,
somehow... (and feel like the overlap affects only the output rate)

this is comparing an overlap of 32 to an overlap of "1" (no overlaps), and
a window size of 8192 (256 being the hop size) - the
how does overlap affect the rms value? If I use an overlap of 32 I see no
difference, except the output rate.

some additions:
the object maintains a summing buffer where it writes the current sum of the
different analysis windows (the number of windows depends on the hop size),
starting with the most recent one.
what happens in the loop is that it takes n input samples, squares them,
multiplies it wi

I'm a Linux user, but I've been using a Dell XPS 15 9550. The form
factor is nice, it's relatively thin and light. I'd say my

Dear list,
I'm looking to buy new laptop and a matching audio interface for daily use
+ audio performance/programming (not video). I would be interested to know
what are the current trends nowadays, and what experiences you have.
My current setup is:

- Lenovo X61s (I'm
