jAudio is a free, open-source digital signal processing application designed for audio feature extraction within Music Information Retrieval (MIR) research. Developed primarily by researchers Daniel McEnnis and Cory McKay at McGill University, it functions as a core component of the broader jMIR software suite.
Its primary purpose is to convert raw, uncompressed audio files (such as .wav files) into a structured numerical dataset. This processed data can then be analyzed by machine learning toolkits (like Weka) for automatic music classification tasks like genre identification, mood detection, and artist recognition.
