title: Converting audio samples into an audible file format
body: <p>I've been trying to convert a huge amount of data (about 900 MB) to an audible file format for a few days now. I've been given a .dat file containing 900 millions floating-point samples (one per line) representing 90 seconds of music at 10 MHz.</p>
  
  <p>I downsampled to 40 KHz but now I don't know how I could possibly listen to the audio hidden in those bytes. I'm writing a C++ program in a Linux environment but if any one knows how to accomplish this task using Matlab, Octave, Python, Audacity, MPlayer or any other tool, please come forth and speak :) Contributions in any amount are greatly appreciated.</p>
