Installation

Lauscher uses the SoundFile package for parsing audio data. On Linux, this library requires you to install libsndfile via your distribution's package manager, e.g. via apt install libsndfile1.

We recommend setting up a virtualenv (you'll need apt install python3-venv or similar) for your lauscher project:

git clone https://github.com/electronicvisions/lauscher.git
cd lauscher
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Usage

Assuming you are working in a private copy of lauscher that has been installed as noted above, you can continue by calculating a first spiketrain from one of the included examples:

python -m lauscher test/resources/spoken_digit.flac my_first_spiketrain.npz --num_channels 70 --verbose

Note that due to the complexity of the implemented model, even short audio files might take multiple minutes to convert. Memory consumption might be huge for long audio files.
