The hardest class I ever had was stochastic analysis (as recent as 4
years ago), where we solved problems like this. Fundamentally, it's
not too hard, but the details of the calculus are tricky. I'd prefer
to stay away unless there's a real good reason to do so :)
Well if you want to stay away from stochastic processes and consider the
signal as a deterministic function, then you'll have to make assumptions
that make sense for functions.
And a flat spectrum isn't. As you said at the very beginning (almost),
assuming it has a flat spectrum implies it is a dirac delta.
Finding the interpolator that best interpolates a dirac delta is finding
the interpolator that best matches the ideal interpolator (the sync),
hence your result.
Ok, we cannot find an interpolator that is optimum for all classes of
functions, so we have to choose some class of functions.
Even provided your reasoning about phase was right (so allowing to
extend the result not only to the delta function but to all function
with a flat spectrum with whatever phase), I don't think the resulting
class of function is much more general and much more interesting.
I think people often use a sinusoid to measure the quality of an
interpolator (e.g. in Miller's book you find tables with the
signal-to-noise ratio of the interpolator measured on a sinusoid, if i
remember correctly).
Maybe you could solve the problem of finding the best interpolator for a
sinusoid.
That would make a lot more sense than the best interpolator for a dirac
delta. (note that I don't know if the result turns out to be the same)
If you try to solve the problem for a whole class of functions of some
interest, I'm afraid you'll find out it is much (much much much) more
complicated than dealing with stochastic processes.
Note that I'm not saying that
E=|f(x)-sinc(x)|^2 is minimized when
f(x)={sinc(x) -2x2 ,0 elsewhere
is a bad choice.
I'm just arguing that your reasoning doesn't prove it is the best choice.
Indeed I think some software use
E=|f(x)-sinc(x)|^2 is minimized when
f(x)={sinc(x) -NxN ,0 elsewhere
for some value of N. For infinite N, this would be the perfect
interpolator, so obviously for large N it is good enough.
The problem is that for N as little as 2, the truncation has
non-negligible effects on the stop band, so the problem arises, whether
another signal can reduce the effects of the truncation on the stop
band, at the cost of some added ripple within the passband.
Now that I think about it, your truncated sync should have perfect-flat
passband response, and big stopband ripples (how do you call the
stopband ripples? cannot remember the word), so any improvement at
stopband will have to be traded off with some increased passband ripple.
So here's what the truncated sync is best at: it's the one with the best
(meaning flattest) bandpass response. Is this correct???
Note however that the highest part of the high frequency noise (due to
the non-zero stopband part of the interpolator) will cause aliasing when
resampling. The analysis of passband ripple and stopband ripple and
whatever measure of their trade off doesn't take this into account: it
just considers the passband ripple as passband distortion, and the
stopband ripple as high-frequency noise. But after resampling part of
that high frequency noise will be brought back to low frequency in form
of aliasing. Note that the new Nyquist frequency depends on the
resampling frequency and is not the same as the original Nyquist
frequency, so how relevant aliasing is depends on the resampling rate.
If yoy resample at 1:1 then _all_ high freq noise will become aliasing.
Aliasing is often considered somewhat worse than anything else (correct
me if I am wrong), I guess because it is specially audible, being
perceived as something completely unconnected to the original signal.
This last digression is nothing specific to the truncated sync, it is
just to say that while trading off between passband distortion and
stopband noise, we have to consider that stopband noise may alias back
to low frequency and hence it is especially important to avoid it.
Hence an interpolator with strong stopband ripple is likely to need to
be used in conjunction with oversampling and filtering before
resampling. By the way when we resample at an unpredictable and varying
rate (such as using a tabreadWhatever~ with an input signal that is not
a ramp), oversampling and filtering is not feasible (or is it???)

Re: [PD] strange colors with pix_record
yes the RGBA channels are set wrong on mac osx. the cube appears blue because the alpha channel is read as blue. when you change channels like this R – G G – R B – A A – B the movie will justified. but it´s not handy to give each record this process so i fixed this with a change in the code of recordQT.cpp in line 241 - instead of colorspace = k32BGRAPixelFormat; i use colorspace = k32ARGBPixelFormat; but i don´t know how this affects other os also the recorded mov is upside down - this can fix in quicktime pro with a click in the properties of the video track - so i don´t looked for the code issue. matthias Am 02.04.2010 um 03:33 schrieb Mathieu Bouchard: Johannes a écrit : you can file a bug report even if it only happens on a single operating system.

[PD] 24 bit / 96 k issue
Hi there, I'm trying to use 96 k/24 bits WAV file in pd for the first time and something weird is happening: when I open such a file, I get an no such oject error in the console, althou I haven't put any unknown object in my patch, then, some GUI elements freeze (knobs, faders...) and I can't use my patch anymore (but the sound seems to play). Find last error doesn't lead me anywhere. Can anyone telle me what's going on or explain me how one to deal with 96k 24 bits sounds in Pd (setup changes, soundcard settings...) I've noticed that switching pd to 96k mode in Pd doesn't affect my ASIO soundcard's settings (it stil shows 16bits, 44100 hz) so I'm kind of mixed up...

[PD] Detect silence inArray and resize
Hi, I'm Trying to do this: after recording a sound event in array (the initial size of this array is equal to samplerate*time in seconds), I want to resize this array approximately equal of the duration of this sound event (as a sttacato event with fff in trumpet). In other words, I want to detect in a array with size X, a lot of amount of samples with values approximately zero, this amount with size Y (where Y is 0YX) , and resize this array with new size X-Y I'm trying to program it or look on the net for solutions, but without sucess. anyone have any idea how to do this?

Hi Guilherme, triggering tabwrite~ with bonk~ may help you get rid of silence _before_ the note, after the note I'm not sure... Personally I would just leave that. What's the reason you want to remove the silence ? You could also detect silence on the sound itself with an envelope follower... off the top of my head: [abs~]--[lop~ 100]--[expr~ $v10.05]--[unsig~]--[change]--[tgl] or something similar ? gr, Tim anyone have any idea how to do this?

[PD] dynamic gui masking problem
By using [canvasdelete] from the iemguts. It allows to delete certain objects of a certain canvas by their index number (for instance, 'delete 12'). The canvas needs a [canvasdelete] in order to add the 'delete' method to the canvas and a [sendcanvas] to which the 'delete id' message is sent. How do you intend to manage those numbers from Pd without ever getting mixed up ? Then I ran into another problem: I was creating [cnv] objects in a GOP and moving them out of the GOP area, which is a way to display something in the parent patch outside the GOP area. However, when deleting such gui objects, they remain visible in the parent (as if the parent wouldn't be refreshed).

[PD] Parallel Circuit
Hello list, I wanted to share a recent piece with you: http://ecmc.rochester.edu/mbarb/web/music.php?filter=chrono#parallel_circuit It's for saxophone quartet and Pd -- all sounds in the piece come from the sax quartet directly, from processing the saxophone sounds, or from synthesis. The piece is in four broad movements, each in four distinct sub-sections (16 total). I use four different equal temperaments in the piece as well: 12 per 2:1 19 per 3:1 24 per 2:1 14 per 3:2 (one of each per broad movement). If you listen, I hope you enjoy.
