Audio manipulation tool

First be sure you have a running Python 3 up and running.

Then start by clone this git project:

git clone https://github.com/opengd/kavel.git

Install dependencies using pip:

pip install ciffi
pip install numpy

You will need to install PySoundFile to get kavel working https://pysoundfile.readthedocs.io/en/0.9.0/#installation

Install PySoundFile using pip:

pip install pysoundfile

On linux you also need to install libsndfile:

sudo apt-get install libsndfile1

python3 kavel.py

Example:

python3 kavel.py -r my_audio_file.flac

This will reverse the input audio file and output a new flac file named "my_audio_file_r_k.flac".

To use paulstretch on a audio file:

python3 kavel.py -s --stretch_amount=2.0 --window_size=1 my_audio_file.flac

This will create a new flac file called "my_audio_file_k_s2.0_w1.0.flac" stretched using paulstretch.
