Description

A new sample accurate but somewhat slow FFmpeg based audio source filter for AviSynth+. No indexing required and only available in 64-bit.

Requirements

• [x64] AviSynth+

Syntax and Parameters

BestAudioSource (string "source", int "track", int "adjustdelay", bool "exactsamples", string "varprefix")

string  source =

Path to audio file. Path can be omitted if the script is in the same folder as the audio file.

int  track = -1

Positive track numbers refer to the FFmpeg given stream number. Negative numbers refer to the nth audio track with -1 being the first.

int  adjustdelay = -1

Delay adjustment.

bool  exactsamples = false

Set to true if you want opening files to be really slow but for some reason need a completely sample exact length.

string  varprefix = ""

Examples

BestAudioSource("blah.mp4", track=-1, adjustdelay=-1, exactsamples=false, varprefix="")
