p5 microphonep5 麥克風

micLevel, bass and beat read the microphone the way p5 reads mouseX: a circle that grows when you speak, and no p5.sound.micLevel、bass、beat 像 mouseX 一樣讀麥克風：說話時圓會變大，不用 p5.sound。

Try these three things試試這三件事

  1. Allow the microphone when the browser asks, then talk, clap or play music: the circle grows with how loud it sounds.
  2. A low voice or a bass line turns the colour towards magenta: that is bass.
  3. No microphone? 🎹 → 🥁 starts the drum machine: each kick and snare sets beat, and the ring bursts.
  1. 瀏覽器問的時候允許麥克風，然後說話、拍手或放音樂：圓跟著聽起來多大聲變大。
  2. 低沉的聲音或貝斯，顏色會往紫紅走：那就是 bass。
  3. 沒有麥克風？🎹 → 🥁 開鼓機：每個大鼓、小鼓都讓 beat 變成 true，外圈彈出一圈。

Needs: Microphone.需要：麥克風。 No hardware? Use Drum machine.沒有硬體？用鼓機。
