I'm currently using child_process and command-line mplayer to play audio on the local machine, with my Node.JS application. This works, but it's not really an excellent solution. My biggest issue is that it takes 500ms from mplayer is started to audio starts playing.
Are there better ways to play audio? Preferably compressed audio, but I'll take what I can get.

I would suggest using node-speaker, which outputs raw PCM data to your speakers (so basically, it plays audio).
If you're playing something like mp3 files you might need to decode it first to PCM data, which is exactly what node-lame does.
Hope that helps.

Simplest I've found (on Mac OS) is to use
exec('afplay whatever.mp3', audioEndCallback) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
