This is Python code for Bag-of-Features representations for acoustic event detection and classification. The method for multi-channel fusion is described in [3] and the single-channel method in [1,2]. It also includes a two demos:

• Classifying single-channel acoustic events on the FINCA acoustic event dataset
• Classifying multi-channel events on the FINCA multi-channel dataset

For details please read the 'Getting started' section

Note that this is a updated version of the code used in the publications ([1,2,3]). Some dependencies have been replaced by python libraries that are easier to handle. If you have used one of our previous - non github - release, the results may differ slightly.

The software was tested on Debian 64bit.

1. Either add the src folder to your PYTHONPATH or use a Python IDE of your liking (e.g. Eclipse and pydev)
2. Use the multi_channel_experiments or the single_channel_experiment sample file to include our code in your experiments

For running the sample experiments:

1. Download the FINCA "Multi-channel acoustic event dataset" for multi-channel experiments or the FINCA "Acoustic event dataset" for single-channel experiments from http://patrec.cs.tu-dortmund.de/cms/en/home/Resources/index.html
2. Set the respective FINCA_DATASET_PATH in the demo file
3. Run the experiment
