I’m fairly new to Ruby and programming in general. I wanted to make a program using the BlinkenLights library(which I already have and know how to use) that would make the LEDs pulsate to the bass of the music. I already have a few other sound libraries but all they do is play sound and detect tags. Is there any libraries or anyway in code I could detect audio playing? ---

What library have you found that plays sound? ---

Are you talking about live audio? If you’re on OS X, you can probably call down to the CoreAudio APIs using either Ruby DL or RubyCocoa, but it won’t necessarily be a picnic. – Giles B.

You might however simply consider looking into one of the game libraries. rubygame gosu etc… they don’t just do games, they do sound and animation and such well. You might look at the C code for VLC player at [videolan.org](http://videolan.org) Pretty slick software, crossplatform, and includes some minimal audio visualizer/analyzer. ---

I’m trying to use rubygame right now, but it keeps giving me a “warning: bad filetype” error for all my audio files. ---

I can’t even install the gem. I tried through the repository and locally but I keep getting some error about it not being able to build native extensions or something? ---

Thanks. I’ll look into all of that. P.S.(To thefed) I was using the win32 sound library. I’m pretty sure it comes with ruby if not its on ruby
