title: Which SQLAlchemy column type should be used for binary data?
body: <p>I want to store audio files in my database.  I know, for example, that strings would use <code>db.String</code>, integers <code>db.Integer</code>, but not what audio data would use.  What data type is used to store this type of data in SQLAlchemy?</p>
  
  <pre><code>class Audio(db.Model):
      __tablename__ = 'audio'
      id = db.Column(db.Integer, primary_key=True)
      timestamp = db.Column(db.DateTime, index=True, default=datetime.utcnow)
      author_id = db.Column(db.Integer, db.ForeignKey('users.id'))
      title = db.Column(db.String(64), unique=True)
  </code></pre>
