amen

A toolbox for algorithmic remixing, after Echo Nest Remix.

Platforms

Amen is developed on Ubuntu 14.04 and higher. OS X should be workable. Windows users should install Ubuntu.

Installation

Amen is pretty simple, but it stands on top of some complex stuff.

If you are on Linux, you'll need libsoundfile: sudo apt-get install libsndfile1. If you're on OS X, read on.

Next, you should install Anaconda, (https://www.continuum.io/downloads) which will get you all of the dependencies.

Then, install via pip: pip install amen. That should be it!

(If you're a serious Python cat, you can just get Amen from pip, without Anaconda - but that will require installing numpy, scipy, a fortran compiler, and so on.)

Testing the Installation

After installation is finished, open up a Python interpreter and run the following (or run it from a file):

from amen.utils import example_audio_file
from amen.audio import Audio
from amen.synthesize import synthesize

audio_file = example_audio_file()
audio = Audio(audio_file)

beats = audio.timings['beats']
beats.reverse()

out = synthesize(beats)
out.output('reversed.wav')

If all that works, you just need to play the resulting reversed.wav file, and you're on your way!

Examples

We've got a few other examples in the examples folder - most involve editing a file based on the audio features thereof. We'll try to add more as we go.

Documentation

You can read the docs at http://amen.readthedocs.io/en/latest! You can also build the docs locally, using Sphinx. Just run make within the docs directory.
