For developers working on audio applications or codecs, having a tool to automatically detect changes between different versions of an audio file is crucial. is a command-line interface (CLI) tool built for this exact purpose. Designed to work like 'git diff' for audio, it can analyze two files and report specific differences in loudness (LUFS), spectral balance, timing, and even detect issues like clipping. This allows developers to automate regression testing in their continuous integration (CI) pipelines.

A standard file finder cannot locate these duplicates if the file names or formats are different. This is where software becomes essential. What is an Audio Comparer?
