 Mixes multiple audio inputs into a single output.
+Note that this filter can only work with float samples (the @ref{amerge}
+and @ref{pan} audio filters support many formats). If the @var{amix}
+input has integer samples then @ref{aresample} will be automatically
+inserted to perform the conversion.
 For example
 ffmpeg -i INPUT1 -i INPUT2 -i INPUT3 -filter_complex amix=inputs=3:duration=first:dropout_transition=3 OUTPUT
