# WCCChallenge_Obscure # ObscureTerrain For this week's Creative Code Challenge by @sableraph: **"Obscure",** **ObscureTerrain** is coded in ***Hydra, LiveCodeLab & SonicPi*** *to* Represent a realm full of obscured traits. ## Obscuring Process * The genre of the sound coded in **SonicPi** is meant to be obscured. What is it? Is it even a genre that can be found on *Spotify Wrapped, YouTube Recap or Apple Music Year Review?* * The main sound heard comes from using various Linear Algebra techniques to further the idea of an obscured way to design sounds. * Through **Hydra & LiveCodeLab,** This terrain is obscured through many geometric shapes and the lasting effect they have. How was this realm originally designed: is it possible to go back? ## Poem ```ocaml What is the Eye Focusing on? What is the sense of touch, rotating upon? What is obscured in the smell of the place Or even in the taste of the space? We may never know We may always know But the information That portion Sorting Is an on going rotation Investigation ``` ## Video ## Code ### SonicPi - Linear Algebra Exploration ```ruby live_loop :matrix do use_random_seed (Time.now.to_i) matrix1 = [[rrand(-5,3),0,dice(3)],[rrand_i(-4,4),dice(4),rrand(-3,4)],[rrand(-2,4),-1,0]] #determinant a = matrix1[0][0] b = matrix1[0][1] c = matrix1[0][2] d = matrix1[1][0] e = matrix1[1][1] f = matrix1[1][2] g = matrix1[2][0] h = matrix1[2][1] i = matrix1[2][2] #determinant formula det_a = a*(e*i - f*h) - b*(d*i - f*g) + c*(d*h - e*g) use_synth :piano play (det_a).abs #matrix math mat_add_A = a + d + g mat_add_B = b + e + h mat_add_C = c + f + i #scalar use_synth :piano play (mat_add_A).abs * 3 play (mat_add_B).abs * 3 play (mat_add_C).abs * 3 sleep [0.25,0.5,1,1.5,2,4,8].choose end live_loop :dotproduct do #dot product formula - scalar use_random_seed (Time.now.to_i) / 3 matrix2 = [[rrand(-5,23),12],[dice(14),rrand(-3,4)]] #vector length, pythagros of multiple dimension vector_subspace = [rrand(-3,5),dice(7),rrand(-2,8),dice(3),dice(4)] for i in 0..vector_subspace.length - 1 do #give constraints for the loops var = vector_subspace[i] #variable var *= var #updating vector_subspace[i] = var #equals the square total = vector_subspace.sum #sums the total after each iteration puts total vec_length = Math.sqrt(total) puts vec_length end #dot product break down ax = matrix2[0][0] ay = matrix2[0][1] bx = matrix2[1][0] by = matrix2[1][1] ab = (ax * bx) + (ay * by) det_ab = (ax * by) + (ay * bx) use_synth :piano play (ab).abs / 2, decay: vec_length use_synth :prophet play (det_ab).abs with_fx :ping_pong, mix: rrand(0.1,0.6) do sample :glitch_perc5 , rate: vec_length, pitch: (det_ab).abs % 16 sample :elec_filt_snare , rate: vec_length, pitch: (det_ab).abs % 16 sample :drum_cymbal_closed, rate: 0.5, decay: (det_ab/vec_length).abs % 7 sample 'C:/Audio/Rambling/JungleJazz.wav',beat_stretch: vec_length, rate: Math.sqrt(dice(25) + 1)/3 end sleep [0.25,0.5,1,2,4].choose end ``` ### SonicPi - Chaotic Overlaying ```ruby live_loop :rollback2 do #making true random as it goes with the actual time #then using the Math.cbrt to make it a different seed ratio then the above function use_random_seed Math.cbrt(Time.now.to_i) use_bpm 75 puts Time.now.to_i with_fx [:echo,:whammy,:ixi_techno].choose, mix: rrand(0.1,0.6) do with_fx :ping_pong, mix: rrand(0.1,0.9) do sample"C:/SonicPi/SocaRiddims/WaterMelonRiddim_Wav.wav",amp: 7, rate: Math.sqrt(dice(25) + 1)/3 sample"C:/SonicPi/SocaRiddims/WaterMelonRiddim_Wav.wav",amp: 7, rate: 0.9 * (Math.sqrt(dice(25) + 1)/3) sample"C:/SonicPi/SocaRiddims/WaterMelonRiddim_Wav.wav",amp: 1.2, rate: 0.75 * (Math.sqrt(dice(25) + 1)/3) sample"C:/SonicPi/SocaRiddims/WaterMelonRiddim_Wav.wav",amp: 3, rate: 0.85 * (Math.sqrt(dice(25) + 1)/3) sample"C:/SonicPi/SocaRiddims/WaterMelonRiddim_Wav.wav",amp: 3, rate: 0.95 * (Math.sqrt(dice(25) + 1)/3) sample"C:/SonicPi/SocaRiddims/WaterMelonRiddim_Wav.wav",amp: 3, rate: 1.05 * (Math.sqrt(dice(25) + 1)/3) sleep [128,64,96].choose end end sleep [0.5,1,2].choose end ``` ### Hydra ```javascript s0.initScreen() src(s0).kaleid(0.03).scale(0.35).blend(s0).add(s0).out() ``` ### LiveCodeLab ```javascript rot = time / 5 animationStyle paintOver if time % 8 > 4 ambientLight 255 noStroke if time % 8 < 4 stroke red ambientLight 124- ((time % 30)*3), 90, 110 + ((time % 23) * 4) ringDetail = 11 if time % 10 > 5 fill orange if time % 10 < 5 fill yellow if time % 12 < 6 rotate rot,Math.hypot(rot, time % 10) scale 0.7 if time % 12 > 6 rotate rot, Math.sqrt(rot), rot scale wave(0.03) 9 times with i rotate (time / 5) + i ringDetail times rotate wave(0.03), Math.cbrt(i), (2 * pi) / ringDetail move 2*i, i, i/5 rect abs(tan(1 - time % 5)), 0.3 + (1 / ringDetail) if time % 14 > 7 fill blue else fill red stroke white animationStyle motionBlur rect Math.hypot(0.3, (3 / ringDetail)),abs(tan(3 - time % 6)),0 ```
