		+
		+	== Description ==
		+	[[MinMaxAudio]] computes the root mean square, maximal or minimal value over all samples in all channels,or just over all samples in channel, and outputs the value (in decibels) as a float[http://forum.doom9.org/showpost.php?p=1197592&postcount=19]. It's a conditional audio filter, so the computation is done framewise.
		+	<br>
		+	<br>
		+	== Requirements ==
		+	* [x86]: [[AviSynth+]] or [https://sourceforge.net/projects/avisynth2/ AviSynth 2.5.8 or greater]
		+	* Supported color formats: N/A

		+	<br>
		+	::{{Par2\| \|clip\| }}
		+	:::Input clip.
		+	<br>
		+	::{{Par2\|channel\|int\|0}}
		+	:::<code>channel=0</code> (default) means that the max/min/rms is taken over all samples in all channels (framewise).
		+
		+	<br>
		+	== Examples ==
		+	<pre>
		+	v = BlankClip(pixel_type="YV12")
		+	a = Tone(type="Triangle", frequency=2, level=0.4)
		+	w = AudioDub(v,a) #.Histogram(mode="audiolevels")
		+	#w = ScriptClip(w, "Subtitle(String(AudioMax(1)))")
		+	w = ScriptClip(w, "Subtitle(String(AudioRMS(0)))")
		+	#w = ScriptClip(w, "Subtitle(String(AudioMin(1)))")
		+	w = w #.ConvertToRGB32.AudioGraph(20)
		+	return w
		+	</pre>
		+	Note that the values are given in decibels (see also [[Histogram#Audiolevels_mode\|Histogram("audiolevels")]] docs for an explanation).
