twine (sound)<\/h1>\n

<<playsound “soundfile.mp3” >> plays the file “soundfile. mp3” from the start
\n<<loopsound $heartbeat >> starts playing $heartbeat, over and over. Note: currently browsers are not that good at looping audio seamlessly – brief silences between loops may occur.
\n<<fadeinsound $heartbeat >> is identical to loopsound, but fades in the sound over 2 seconds.
\n<<unloopsound $heartbeat >> makes $heartbeat no longer repeat when it finishes.
\n<<stopsound “birds.ogg” >> stops playing “birds.ogg”. When <<playsound “birds.ogg” >> is used again, it will start from the beginning.
\n<<fadeoutsound “birds.ogg” >> is identical to stopsound, but fades out the sound over 2 seconds.
\n<<pausesound “trees.ogg” >> pauses “trees.ogg” at its current location. Use <<playsound “trees.ogg” >> to resume it.
\n<<stopallsound>> stops all the sounds.<\/p>\n

Make sure that the Macro Passage is the exact filename of your sound file: e.g., soundfile.mp3 or\u00a0 tenori.wav, etc<\/p>\n<\/header>\n
