[edit] 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[1]. It's a conditional audio filter, so the computation is done framewise.

[edit] Requirements

• [x86]: AviSynth+ or AviSynth 2.5.8 or greater
• Supported color formats: N/A

[edit] Syntax and Parameters

AudioMin (clip, int "channel")

AudioMax (clip, int "channel")

AudioRMS (clip, int "channel")

clip   =

Input clip, audio is converted to float internally.

int  channel = 0

channel=0 (default) means that the max/min/rms is taken over all samples in all channels (framewise).

[edit] Examples

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

Note that the values are given in decibels (see also Histogram("audiolevels") docs for an explanation).
