                <h3>How to Create a Panner Interface</h3>

                <p>
                    This is an example of how to add an arbitrary Web
                    Audio node into a wavesurfer.js graph. Panner node
                    is one such node.

                        Create a panner node and add it to the Web
                        Audio graph using the <code>setFilter</code> method.

                        In your HTML, add a range input.

                    <p>
                        Listen to the range input's <code>input</code> event and set the panner's position
                        according to the input's value.
