# au

[au](http://jbroadway.github.io/au/) is a little script to make [ffmpeg](http://www.ffmpeg.org/) and [sox](http://sox.sourceforge.net/) easier to use for common audio manipulations like cutting to a specific number of beats at a set BPM, volume adjustments, joining files together, and converting between file formats or between mono and stereo. I made this to automate the job of preparing files for various audio hardware that I use in my live shows.

### Setup

1. install [ffmpeg](http://www.ffmpeg.org/) and [sox](http://sox.sourceforge.net/) (Linux users may need to install [PHP](http://php.net/) too)

2. save the `au` file to your `~/bin` folder

3. chmod the file to be executable:

         chmod u+x ~/bin/au

You're all set, now run:

    au help

### Available commands

    au cut    input.wav 120 16 ouput.wav                     # cut file to specified bpm*beats for making loops

    au join   file1.wav file2.wav [...file3.wav] output.wav  # join files together to make one audio file

    au pad    input.wav end 2.0 padded.wav                   # pad start or end of file with silence

    au vol    input.wav 0.5 output.wav                       # adjust the volume of a file

    au mp3    input.wav output.mp3                           # convert to an mp3 of the same name

    au wav    input.aif output.wav                           # convert to a wav of the same name

    au mono   stereo.wav mono.wav                            # convert stereo to mono

    au stereo mono.wav stereo.wav                            # convert mono to stereo

### Examples

    # cut verses.wav to 4 bars at 132bpm

    au cut verses.wav 132 16 verses-cut.wav

    

    # convert aif to wav (saves to verses.wav)

    au wav verses.aif

    

    # halve the volume of a clip (overwrites verses.aif)

    au vol verses.aif 0.5

    

    # join some files together as song.wav

    au join verse.wav chorus.wav verse.wav song.wav

    

    # pad a file with 2 seconds of silence at the end

    au pad song.wav end 2.0 padded.wav
