[[Waveform|Waveform v2.0]] is a rewrite of the older Waveform v0.3 plugin with the following improvements:
  
−
Improvements over AudioGraph are:
+
* Support for all AviSynth+ colourspaces
−
*A nicer, variable height overlay
+
* Anti-aliased waveforms
−
*Separate graphs for each channel, works with an arbitrary number of channels
+
* Fewer crashes, hopefully
−
*Works with YV12 video, as well as RGB24/RGB32/YUY2
+
* When using "zoom" it no longer looks like the waveform is clipping if it goes out of bounds
−
*Audio format is passed through unchanged
+
* Uses min/max of samples for a more accurate display of sample values
 +
* The "window" parameter is no longer restricted to integer values

[edit] Description

Waveform is a plugin to overlay audio waveforms on video clips - useful for identifying sync issues and audio glitches.

Waveform v2.0 is a rewrite of the older Waveform v0.3 plugin with the following improvements:

  • Support for all AviSynth+ colourspaces
  • Anti-aliased waveforms
  • Fewer crashes, hopefully
  • When using "zoom" it no longer looks like the waveform is clipping if it goes out of bounds
  • Uses min/max of samples for a more accurate display of sample values
  • The "window" parameter is no longer restricted to integer values


[edit] Requirements


[edit] Syntax and Parameters

Waveform (clip, float "window", float "height", float "zoom", bool "under", bool "smooth", bool "aa")


clip   =
Input clip; must contain audio and video.


float  window = 0
The number of frames either side to display a waveform for.


float  height = 0.333
  • >=1 : height in pixels of waveform overlay
  • <1 : total height of waveform display as a fraction of video height.


float  zoom = 1.0
Scale up the waveforms.


bool  under = false
Display the waveform underneath the video instead of superimposed on it.


bool  smooth = false
Smooth out waveforms.


bool  aa = true
Anti-aliasing.


[edit] Examples

Waveform with default values: 

AviSource("blah.avi") # make sure clip has audio and video
Waveform(window=0, height=0.333, zoom=1.0, under=false, smooth=false, aa=true)


[edit] Changelog 

Version      Date            Changes

v2.0.2       2022/11/13      - adds frame property pass-through support

v2.0         2021/05/15      - v2.0 initial release

v0.3         2015/02/28      - new parameter: "marks"
                             - mitigate crash when "window" is set to high values

v0.2         2012/10/06      - commented out the function which uses vsprintf_s
                             - hopefully fixed those rowsize/pitch issues (but only for YV12/YUY2 so far)
