acsuite-orangechannel 4.1.3

Frame-based cutting/trimming/splicing of audio with VapourSynth.

acsuite

audiocutter(.py) replacement for VapourSynth.

Allows for easy frame-based cutting/trimming/splicing of audio files using VapourSynth clip information.

Functions:

eztrim(clip, trims, audio_file[, outfile, mkvmerge_path=, ffmpeg_path=, quiet=])

import vapoursynth as vs
core = vs.core
from acsuite import eztrim

file  = r'/BDMV/STREAM/00003.m2ts'
afile = r'/BDMV/STREAM/00003.wav'  # pre-extracted with TSMuxer or similar

src = core.lsmas.LWLibavSource(file)

# for the example, we will assume the src clip is 100 frames long (0-99)
trimmed_clip = src[3:22]+src[23:40]+src[48]+src[50:-20]+src[-10:-5]+src[97:]

# `clip` arg should be the uncut/untrimmed source that you are trimming from
eztrim(src, [(3,22),(23,40),(48,49),(50,-20),(-10,-5),(97,0)], afile)

Outputs:

• If you have ffmpeg in your PATH or specify a path to an FFmpeg executable with ffmpeg_path='/path/to/ffmpeg.exe', the script will automatically output a waveform audio file (.wav) named /BDMV/STREAM/00003_cut.wav.

• If not, the script will output a Mastroka Audio file (.mka) named /BDMV/STREAM/00003_cut.mka.

MKV container example

import vapoursynth as vs
core = vs.core
from acsuite import eztrim

# no need to extract audio if using a container with a slice-able audio codec
file = r'/path/to/remuxed_bdmv.mkv'  # Video: V_MPEG4/ISO/AVC, Audio: A_PCM/INT/LIT

# trimmed_clip = src[0:-22]
eztrim(core.lsmas.LWLibavSource(file), (0, -22), file, 'custom_name.mka')

Outputs:

• If you have ffmpeg in your PATH or specify a path to an FFmpeg executable with ffmpeg_path='/path/to/ffmpeg.exe', the script will automatically output a waveform audio file (.wav) named custom_name.wav in the directory the script is running from.

• If not, the script will output a Mastroka Audio file (.mka) named custom_name.mka in the directory the script is running from.

Getting Started

Dependencies

• MKVToolNix
• VapourSynth R49+

Optional Dependencies

• FFmpeg - needed to output WAV files instead of Mastroka Audio (MKA)

Installing

Arch Linux

Install the AUR package vapoursynth-tools-acsuite-git with your favorite AUR helper:

$ yay -S vapoursynth-tools-acsuite-git

Gentoo Linux

Install via the VapourSynth portage tree.

Windows / Other

Use the Python Package Index (PyPI / pip):

python3 -m pip install --user --upgrade acsuite-orangechannel

or simply

pip install acsuite-orangechannel

if you are able to use a pip executable directly.
