Scripts:

There are 4 separate scripts that need to be run from the terminal:

1. MRaudioChopper
2. MRaudioChopperSliding
3. MRaudioStitcher
4. MRaudioStitcherSliding

You need to have ffmpeg (https://ffmpeg.org) installed for the scripts to work. The scripts are pretty basic and dumb. No serious error checking or input checking is done, therefor the following rules should be observed:

• The folder in which the script is run must only contain audio files
• Create 3 subfolders called:
  • shortStart
  • shortEnd
  • shortSliding

MRaudioChopper

cd folder/with/sound/files/ to the folder containing the sound files...

Run MRaudioChopper arg where arg is an integer value that is the amount in seconds the audio file is chopped to. A positive value trims the file from the beginning and expects a folder named /shortStart in the pwd.

A negative value trims it from the end and expects a folder named /shortEnd in the pwd.

The resulting file is transcoded to a .aiff at 44.1kHz

no checks are made if the files in the directory are actually soundfiles... no checks are made if /shortStart exist

MRaudioChopperSliding

cd folder/with/sound/files/ to the folder containing the sound files

Run MRaudioChopperSliding (no arguments)

The script takes into account the number of files in the directory to decide on the starting point of the trim -> each file will start a bit further into the file therefore sliding through all files by the end. This means that for the first couple of files mostly the beginning of the files will be heard and towards the last files only the ending of the files.

The duration of the files is 30sec + 1% of the total length of the current file.

The trimmed version is saved to /shortSliding

The resulting file is transcoded to a .aiff at 44.1kHz

no checks are made if the files in the directory are actually soundfiles... no checks are made if /shortSliding exist

MRaudioStitcher

cd to either /short[Start/End]

Run MRaudioStitcher (no arguments)

Decides on a random cross-fade based on the length of the current file.

Final file is named output.aiff and should be moved and renamed before running this script again or it will be overwritten!!

MRaudioStitcherSliding

cd to /shortSliding

Run MRaudioStitcherSliding arg where arg is a positive integer value that is subtracted from the total length of the file, in seconds, and used as the cross-fade time

Final file is named output.aiff and should be moved and renamed before running this script again or it will be overwritten!!

Typical usage:

cd /folder/with/audio
MRaudioChopper 20
cd /folder/with/audio/shortStart
MRaudioStitcher

or

cd /folder/with/audio
MRaudioChopper -20 
cd /folder/with/audio/shortEnd
MRaudioStitcher

or

cd /folder/with/audio
MRaudioChopperSliding 
cd /folder/with/audio/shortSliding
MRaudioStitcherSliding 4

It is of course also possible to run MRaudioStitcherSliding on /short[Start/End]:

cd /folder/with/audio
MRaudioChopper -20 
cd /folder/with/audio/shortEnd
MRaudioStitcherSliding 2
