Developer Alex Radzishevsky lets us know that he’s released an update to AFT SonicDecloner, his free acoustic de-duplication tool.

AFT SonicDecloner is a command-line tool that lets you scan through all your audio files and find duplicates, even if they are named differently. Unlike traditional file comparison methods, this tool ‘listens’ to audio files just like the human ear, and identifies duplicates originating from the same performance or recording, regardless of file compression or format.

AFT SonicDecloner v1.1 adds recursive subfolder scanning, with unlimited depth, formatted CSV reports for easier data analysis and more.
Key Features:

• Acoustic-level detection: utilizes sophisticated acoustic fingerprinting algorithm (AFT) to analyze actual sound content, not just file metadata or binary data
• Format and compression agnostic: works with all major audio formats and codecs
• Robust: works with distorted, pitch-shifted and speed-altered audio
• Does *NOT* delete your files, only reports!
• Recursive scanning — automatically searches for audio files in subfolders
• Generates detailed formatted reports — outputs analysis results in TXT and CSV formats
• Freeware – free for non-commercial use
• Cross-platform software: Windows, Mac OS, Linux
• Portable, does not require installation
• Works offline and is fully stand-alone
• Supports for batch processing via command-line
• Old-school text interface
