Audio A/B Tester
Audio A/B Tester – Technical Specifications
The Audio A/B Tester is an intelligent desktop utility designed to help producers, sound engineers, and AI developers compare two audio sources side-by-side in real time. Built entirely in Python, this open-source tool provides an intuitive graphical interface for loading, playing, and visually analyzing sound files — making it ideal for before-and-after comparisons in mastering, AI voice synthesis, or audio restoration workflows.
Powered by a robust set of Python libraries, the app combines Tkinter for the GUI, PyDub and Mutagen for audio decoding and metadata extraction, SimpleAudio for real-time playback, and Matplotlib + NumPy for detailed waveform visualization and playback progress tracking. The tool supports both WAV and MP3 formats, automatically displaying duration, sample rate, and channel information upon file load.
Common use cases include:
🎧 A/B testing processed vs. unprocessed tracks (mixing, mastering, AI enhancement)
🧠 Comparing AI-generated vocals to original recordings for quality evaluation
🧪 Auditioning different effects chains or processing algorithms
🎙️ Research in machine learning-based sound modeling and restoration
The Audio A/B Tester is part of the broader Intelligent Audio Utilities suite — a collection of smart tools bridging music technology and AI. Designed for accuracy, simplicity, and cross-platform compatibility, this project demonstrates how Python can deliver professional-grade audio analysis in a lightweight, open-source package.
