jAudio is an open-source, Java-based audio feature extraction application specifically designed for Music Information Retrieval (MIR) research. Originally developed by Daniel McEnnis, Cory McKay, and Ichiro Fujinaga at McGill University, it serves as a cornerstone of the broader jMIR software suite.
The primary goal of jAudio is to standardize and simplify how researchers turn raw digital audio into structured numerical data, eliminating the need to continuously re-code foundational digital signal processing (DSP) algorithms. Core Architecture and Features
Unlike standard programming libraries that require steep coding knowledge, jAudio provides both a Graphical User Interface (GUI) for quick point-and-click operations and a Command-Line Interface (CLI) for automated batch processing.
Its framework divides data extraction into three specialized classes: An Evaluation of Audio Feature Extraction Toolboxes – NTNU
