<tone-example label="Stereo Merge">
<div slot="explanation">
<a href="https://tonejs.github.io/docs/latest/classes/Merge"
>Tone.Merge</a
>
combines two mono signals into the left and right channels of
a single stereo signal. The channel is chosen by the
<code>inputNumber</code> argument of

href="https://tonejs.github.io/docs/latest/classes/ToneAudioNode#connect"
>connect</a
>: <code>0</code> is left, <code>1</code> is right. Put on
headphones and toggle each oscillator separately to hear the
difference.
