above all, have fun :hibiscus:

• ffs (should be just an expr (3 actually) and a bicoeff) (bail out)
  • i mean it's not too bad, you're limited to control rate but that's never been a problem for this use https://github.com/tomara-x/moths/blob/flutter/practice/filter-tests.pd
• pd~ (/lib/pd)
• hv.line
• clave
• arrays for envelopes?
• https://github.com/tomara-x/waste/issues/1
• non linear saturation and clipping (can u make it like an eq?)
• scanning bandpass..
• mult and wrap the multiplier
• raw filters! [rpole~] [rzero~] [rzero_rev~]
• high freq = high q (so with lower frequencies you get lower resonance)
• revisit speck and nullity
• morpheus
  • morphing exclusion logic is fucked, it's gonna stop it from loading a preset (from file) if there's only one slot saved
  • make it smaller (yes pls)
  • multichannel? (don't think so, you add one snake and the whole thing turns into snakes)
  • change [*] to [* 0]
  • add glide
• trail
  • give it a back-switch (idk) (maybe with a color selection method?)
  • bg color
  • does it repaint the whole canvas? no, only needed part gets repainted
  • gimme output too (x, y, color)
• array define pointer
• step 1 (gdb)
• biquad narrowband?
• makefilename pointer
• do the many tables in one long table morphing thing
• function end points reset to min (not 0) (what if 0 isn't in range tho?)
• mtx.ctl
• [biquad~ 0 0 0 1 0] (one sample delay) [biquad~ 0 0 0 0 1] (2 samples)
• listatom double init
• dynamic
  • bounds <x1> <y1> <x2> <y2>
  • map 0, map 1 (what does that do? canvas redrawing related?)
  • write [symbol] [defsymbol]
  • read [symbol] [defsymbol]
  • mergefile [symbol] [defsymbol]
  • sort
  • print [symbol]
  • texteditor
  • protectmode [deffloat]
  • graph [name] [xmin] [ymax] [xmax] [ymin] [x_from] [y_to] [x_to] [y_from]
  • donecanvasdialog [xunit?] [yunit?] [gop. 0=no graph, 1=show graph, 2=show graph and hide name] [xmin] [ymax] [xmax] [ymin] [height] [width] [viewport-pos-x] [viewport-pos-y] [hide-graph]
  • coords [x_from] [y_to] [x_to] [y_from] [width] [heigth] [graph_on_parent]
  • lol um actually! graph_on_parent is like this, 0 = no graph, 1 = show graph, 2 = show graph and hide name
  • mouse x y [mouse_butt. 1=left,2=middle,3=right] [modifier. 1=shift, 2=ctrl, 4=alt]
  • right is special case, it's x y 3 8 and doesn't have a corresponding mouseup
  • selection with mouseup at different coordinates (has to start on an empty space)
• test graph abstractions (what's with the slowness?)
• ⬣w⬣
  • make a button able to belong to more than one hold group (don't think so)
  • make a "clear groups" button (ez)
• plush doll source
  • https://github.com/pure-data/pure-data/blob/master/src/g_canvas.c#L1987 :fish:
• file ops can be hazardous

notes:

• ref: nth iolets, float/sig should get oranges and not blues, argument/flag descriptions line wrap
• [pointer], [netreceive], [text sequence], [pipe], [append] (the rightmost of three with an optional mid) (need a rightmose specifier. i think PdLibrary.cpp)
• [inlet~] reads reference of [inlet] (same for [outlet~]) (works correctly if ref is loaded from the object browser)
• blcok~ and switch~ both read the block~ ref. (h/vradio and h/vsl)
• the floating point precision problem, the one with [autotune2] (that's not us, it's pd)
• [text define] editor freeze(ish) with large texts

our love, our love, 🦋

kisses :kiss:

fuck that:

• fft = freaky fourier transform, stft = smol twink fourier transform
• $\ X(m) = \displaystyle\sum_{n=0}^{N-1} x(n)[\cos(2\pi n m / N) - i \sin(2\pi n m / N)] $
  • X(m) : the mth dft output component
  • m : index of dft output in frequency domain [0, N-1]
  • x(n) : the sequence of input samples
  • n : time domain index of input samples [0, N-1]
  • i : sqrt(-1)
  • N : number of input samples and number of frequency points in dft output
• $\ f_{analysis}(m) = mf_s/N $
• $\ X{mag}(m) = \sqrt{X{real}(m)^2 + X_{imag}(m)^2 } $
• $\ X\theta(m) = \tan^{-1}(X{imag}(m)/X_{real}(m)) $
• ^ those 2 are car2pol? (yeah?)
• radix-2 fft :butterfly: structures
• :tulip: the threshold is cause the output will have some really smol values that you don't really care about, but will fuck up how the plot looks especially after converting to magnitude and phase (i think that's where window functions come in?)
• :seedling: the output of rfft is from dc to nyquist, so faster when doing non-complex analysis (:exclamation: study this)
  • is it better than doing 2 real-fft for stereo? (nah that's a different deal)
• [lrshift~] :bangbang:
• [blocksize~] flags :pirate_flag:
• [hann~], also [tabgen] can do other window functions :window:
• :rose: [block~] can do overlap
• :cherry_blossom: try filters and reverb on the bins
• hop size :rabbit: (lol i still don't know if it's blocksize/overlap, or what)
• :white_flower: [tabreceive~]/[tabsend~] and test expr/fexpr (lol baby you don't need fexpr for that!)
  • how do you read indexed sample from block? (csound vaset/vaget)
    • write to array then read
• phase:
  • atan2 works, atan(imag/real) workn't
  • phase dances with higher overlap! (it's called scalloping (that's with mag tho) :shell:)

• leakage is an unavoidable fact of life when we perform the DFT on real-world finite-length time sequences

  • you hear that? leakage is an unavoidable fact of life :sweat_drops:

TIME TO GET GROOVAY

[tomara-x]

• admissibility condition (no zero frequency component) (0fc is average value of function) $\ \displaystyle\int_{-\infty}^{+\infty} \Psi(t)dt = 0 $

• finite energy $\ \displaystyle\int_{-\infty}^{+\infty} |\Psi(t)|^2dt < \infty $

• morlet (sounds cute af!) $\ \displaystyle\Psi(t) = k_0 \cdot cos(\omega t) \cdot e^{-t^{2}/2} $ $\ k_0$: normalization constant, $\omega$: freq (and the e stuff is just a gaussian window) (almost morlet) $\ \displaystyle\Psi(t) = k \cdot e^{i\omega_0t} \cdot e^{-t^{2}/2} $ $\ \omega_0$: freq

aren't you a beauty

 

is that how it works? you multiply by the wavelet, and so the frequency of the wavelet is gonna resonate with the frequencies in the input signal and that's how you know that frequency is present? that doesn't sound very fast. like, wouldn't that be really bad in real time?

• test this in crisp
• find the definitions for other wavelets (and implement them)
  • the Daubechies 4 in a pd patch :sob:
• [expr] has an exp function! use that instead of raising to e manually

root, grant me the serenity to accept the buffers i can't write to, the courage to change the ones i can, and the wisdom to know access permissions
