jruby + processing + audioinput
さっきは会社でこっそりカメラを叩いたのだけど、コミューン(仮住まい)でオーディオまわりをば。使うライブラリは↓これ。
Minim: An Audio Library for Processing | Compartmental
require "java" include_class "processing.core.PApplet" include_class "ddf.minim.Minim" include_class "ddf.minim.AudioInput" include_class "org.tritonus.share.sampled.FloatSampleBuffer" class Sketch < PApplet def setup size(320,240) Minim.start(self) @inp = Minim.getLineIn(Minim::MONO, 320, 44100, 16) end def draw background(0) stroke(255) (@inp.left.size-1).times do |i| line(i, 50+@inp.left.get(i)*50, i+1, 50+@inp.left.get(i+1)*50) end end def stop Minim.stop super stop end end JFrame = javax.swing.JFrame def run applet frame = JFrame.new applet.class.to_s frame.content_pane.add applet frame.default_close_operation = JFrame::EXIT_ON_CLOSE applet.init frame.pack frame.visible = true end if $0 == __FILE__ run Sketch.new end
examplesにあった内蔵マイクからの音声入力波形を表示。これもいけた。
