  • Unlinking Stereo Channels III

    January 15th, 2013
    experiment, math, music, sound, tech, vsl1818
    Success! I can now display eight independent mono channels to the user while internally representing that as four stereo channels. Before I was struggling with how to extract the underlying equations that VSL is using to turn gain/pan into left/right, but I decided to give up and just brute-force it. I made a giant table (csv):
      pan, gain, left, right
      ...
      34, 80, 0.783, 0.69
      34, 81, 0.793, 0.701
      34, 82, 0.804, 0.712
      34, 83, 0.815, 0.717
      34, 84, 0.821, 0.728
      34, 85, 0.832, 0.739
      34, 86, 0.842, 0.75
      34, 87, 0.853, 0.761
      34, 88, 0.859, 0.766
      34, 89, 0.87, 0.777
    
    Then to implement to_left_right(gain, pan) and to_gain_pan(left, right) I just find the table row that best corresponds to the desired conditions and use that. So if I call to_gain_pan(left=0.83, right=0.74) it will probably identify the line 34, 85, 0.832, 0.739 as closest and so decide to set gain to 85% and pan to 34%.

    It bothers me a little to use something so inefficient (Index it! Figure out the equations!), but it's fast enough. And it works. So now I can use all eight channels for their own mixes.

    Buckingham Palace

    I love England. Especially because of the big castle called Buckingham Palace. I got to see the outside there, but my mom showed me some pictures of the inside. I love it there. But the outside doesn't look very fancy to me. But I never knew why those …
