title: Combining multiple audio files in ruby
body: <p>I'm trying to combine two or more audio files in ruby. I don't need to concatenate the files, but rather combine or merge them. For example, if I have one audio file that is the guitar part to a song, and one audio file that is the bass part, I want to combine the two files and have one file with both the guitar and bass parts.</p>
  
  <p>Is this possible, and if so could somebody point me in the right direction? Googling didn't help much.</p>
