[![Documentation Status](https://readthedocs.org/projects/acsuite/badge/?version=latest)](https://acsuite.readthedocs.io/en/latest/?badge=latest) [![Code style: black](https://img.shields.io/badge/code%20style-black-000000.svg)](https://github.com/psf/black)

audiocutter(.py) replacement for VapourSynth.

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

Includes some extra tools for working with audio files or timestamps.


## Functions:

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

```py
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,None)], afile)
```

##### Output:

Uses the file extension of the input _audio_file_ to output a cut/trimmed audio file with the same extension. If no _outfile_ is given, defaults to `audio_file_cut.ext`.

### concat(audio_files, outfile[, ffmpeg_path=, quiet=])

```py
concat(['file.aac', 'file2.aac'], 'outfile.aac')
```

Will concatenate a list of audio files (paths given as strings) into one file using FFmpeg.

---

## Utility Functions:

### f2ts(f, src_clip=[, precision=, timecodes_file=])

Useful for finding the timestamp for a frame number.

```py
from functools import partial
import vapoursynth as vs
core = vs.core

clip = core.std.BlankClip()
ts = partial(f2ts, src_clip=clip)

ts(5), ts(9), ts(clip.num_frames), ts(-1)
# ('00:00:00.208', '00:00:00.375', '00:00:10.000', '00:00:09.958')
```

### clip_to_timecodes(src_clip)

Returns a list of timecodes for VFR clips. Used as a fallback when *timecodes_file* is not given to `f2ts` or `eztrim`.

## Getting Started

### Dependencies
- [FFmpeg](https://ffmpeg.org/)
- [VapourSynth R49+](https://github.com/vapoursynth/vapoursynth/releases)

### Installing

#### Arch Linux

Install the [AUR package](https://aur.archlinux.org/packages/vapoursynth-tools-acsuite-git/) `vapoursynth-tools-acsuite-git` with your favorite AUR helper:

```sh
$ yay -S vapoursynth-tools-acsuite-git
```

#### Gentoo Linux

Install via the [VapourSynth portage tree](https://github.com/4re/vapoursynth-portage).

#### Windows / Other

Use the [Python Package Index (PyPI / pip)](https://pypi.org/project/acsuite-orangechannel/#description):

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

or simply

```sh
pip install acsuite-orangechannel
```

if you are able to use a `pip` executable directly.
