[edit] Description

An audio plugin with 2 functions: ViewAudio and CacheAudio. Based on Richard Ling's original AudioGraph.

[edit] Requirements

• [x86]: AviSynth+ or AviSynth 2.5.8 or greater
• [x64]: AviSynth+
• Supported color formats: YUY2, YV12

[edit] Syntax and Parameters

[edit] ViewAudio

ViewAudio (clip, int "frames", int "top", int "height", bool "fill", int "channel")

clip   =

Input clip; must contain audio and video. Only 8-bit or 16-bit mono or stereo audio allowed. Use ConvertAudioTo16Bit() if needed.

int  frames = 2

Specifies the number of backward and forward frames. Maximum values is 10.

int  top = -1

Waveform position (Y coordinate):

• -1 : waveform will be added to the bottom on the input clip.
• 0 : waveform will be superimposed at the very top of the input clip.

Higher values specify the distance (in pixels) from the top of the input clip where the waveform will be superimposed.

int  height = 80

The height of the waveform; width will always be the same as the input clip.

bool  fill = true

Fill background; top must be greater than -1, otherwise this parameter is ignored.

• true : waveform will be filled with a black background.
• false : waveform will be superimposed onto the input clip.

int  channel = -1

What channel(s) to display:

• -1 : both channels
• 0 : left channel only
• 1 : right channel only

[edit] CacheAudio

CacheAudio (clip, int "MaxFrame", int "BlockFrame")

clip   =

Input clip; must contain audio and video. Only 8-bit or 16-bit mono or stereo audio allowed. Use ConvertAudioTo16Bit() if needed.

int  MaxFrame = 1000

Specify the maximum number of cached frames.

-1 caches all frames; requires large amount of memory and initialization may be slow.

int  BlockFrame = 100

Specifies the number of frames to be read at once.

-1 will use the same value as MaxFrame; also requires large amount of memory and initialization may be slow.

[edit] Examples

ViewAudio with default values:

AviSource("blah.avi") # make sure clip has audio and video
ViewAudio(frames=2, top=-1, height=80, fill=true, channel=-1)

CacheAudio with default values:

AviSource("blah.avi") # make sure clip has audio and video
CacheAudio(MaxFrame=1000, BlockFrame=100)
