	49
	50	<output> determines whether output is to be rendered into
	51	a) new file,
	52	b) replace the input file,
	53	c) create a sox-command as a pipe (for further processing),
	54	d) play back in realtime through audio device.
	55
	56	Alternatively, a filename, directory, or path can be provided which will write an audio file to the given destination.
	57	It is also posisble to connect a function/patch in lambda mode, which (if available) will receive the path of <sox-input> as first argument.
	58	This can be used to algorithmically name output files (e.g. in batch processes).
	59
	60	Optionally, the audio output <filetype> can be specified, as well as the <samplerate> and <bitdepth> (default: same as input).
	61	<recursive> is an experimental option allowing to apply a sox-effect recursively to audio input (e.g. trimming).
	62	<batch-mode> determines the behaviour when processing lists of sox-inputs and sox-effects that differ in length.
