of sinusoids.
        The argument is a list where every element can be:
      </p>

      <ul>
        <li>
          value &#x2013; relative stregth of the partial. A negative value
          implies a phase inversion. The number of the partial is the position
          in the list plus a possible offset introduced by a previous list
          <code>(partial-number strength [phase] [dc])</code>. The following
          examples generate the same waveform:
