title: what type of sql db can store sound or array data in a column?
body: <p>I need to attach, create a new column in a sql db. It should store the numeric numpy representation of a user's voice - numpy array or an image - spectrogram. 
  numpy array looks like this:</p>
  
  <pre><code>array([[  2.891e-07,   2.548e-03, ...,   8.116e-09,   5.633e-09],
         [  1.986e-07,   1.162e-02, ...,   9.332e-08,   6.716e-09],
         ...,
         [  3.668e-09,   2.029e-08, ...,   3.208e-09,   2.864e-09],
         [  2.561e-10,   2.096e-09, ...,   7.543e-10,   6.101e-10]])
  </code></pre>
  
  <p>I know sql can only store text data, wonder if it s possible to attach or represent shortly the array in a  column.</p>
  
  <pre><code>ID |    date     | voice
  1    01-01-20      array([[  2.891e-07,   2.548e-03...
  2    01-02-20      array([[  2.891e-07,  
  </code></pre>
