Audio analyse

I've added support for avisynth post effects to DVD slideshow GUI. And through avisynth support for Free Frame plugins.

Now I wonder is there a way to analyse the audio in avisynth-script in a way that the current frame can be manipulated through the values of the current volume/frequency ect.?

This is what I have come up with so far:

I guess that a combination of FrameEvaluate and a new Runtime Function could be the best way to value/volume ect. return values into ex. a Free Frame plugin. Unfortunately I don't know how to code this kind of stuff...

Alternatively another way could be to get sox to analyse a wav file and export to a .dat file. I have to figure out if it is possible to export a value pr. frame, matching the framerate and then use ConditionalReader to read the .dat file into a variable which can be used in ex. a the Free Frame plugin.

Any other idears or ways to get sound to manipulate images?

Hmm I just came across the audiograph plugin. If I just knew a bit about this c stuff... I guess it wouldn't be that hard to make it return a max value of the waveform of the current frame instead of a clip...

Can anyone help me with this?

Histogram(mode="audiolevels") returns the maximal value on a frame. So the math is already there. It doesn't look that hard to add this to conditional_functions.cpp, but i have no time for it coming two weeks.

If you are still interested, try this avisynth.dll:

Syntax:
AudioMax(channel) # maximal volume in channel (framewise)
AudioMin(channel) # minimal volume in channel (framewise)
AudioRMS(channel) # root mean square volume in channel (framewise)
# channel = 0 means that the max/min/rms is taken over all samples in all channels (framewise)

Usage:
Code:
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 docs for an explanation).

Will these functions be added to the next avisynth version? :-)

Btw. does anyone else get these errors in MPC(or is it something with my set-up(ffshow - whatever)))?

It's properly not avisynth which is causing the problem. It's Media Player Classic(even the latest builds). It' doesn't matter if I throw audiograph, histogram or your new functions at it, then it gives me the access violation error mentioned above.
I forgot to ask. Does this also happen with older versions of AviSynth, or only the latest official alpha?

Yes it seems so. Histogram actually works, but normalize doesn't.

But I'm affraid it might be something in my set-up. Resently Directshowsource doesn't load mp3 anymore properly. FFshow doesn't fix it.

But is it only here these errors with MPC happen?

Here's some crazy stuff I did with your new functions, DVD slideshow GUI, freeframe.dll and the freeframeplugin: Petebloom.dll.

Audio effects in FLV player

Still haven't found the reason why MPC crashes, when using those sound functions...

@tin3tin,

I created a plugin out of it:

http://www.geocities.com/wilbertdijk...xAudio_v01.zip

The reason that it will not be included in the core (for now) is stability, but IanB is able to explain that better.

It seems that the audio related bugs has been solved in Avisynth 2.6, so I've been playing around with Wilbert's minmaxaudio plugin. It works quite well, however once in a while the resulting value drops out of the 0 to -100 DB range and gives a value like -791 and that causes problems because I need values between 0 and 1. I've been using AudioRMS function. Is this a bug?

Sounds a bug to me. You got a sample clip and script for me?
