Alex Radzishevsky has announced the release of a dedicated freeware audio de-duplication tool that automatically detects acoustically similar audio files (duplicates or “clones”) within a folder.
Instead of comparing bits and bytes, the tool actually “listens” to the sound – just like a human ear would. It utilizes a sophisticated, proprietary, and patented acoustic fingerprinting algorithm, part of AFT – Audio Fingerprinting Tools of www.AudioWatermarking.com and www.AudioTag.info, to match audio content by analyzing acoustic data, regardless of file format or compression. The AFT algorithm focuses on matching the acoustic data, not the melody, and only identifies clones when the audio recordings originate from the same performance or original source.
The tool is completely stand-alone and works offline. It accepts a wide range of audio file formats with the following extensions: mpg, mp2, mpe, mpv, ogg, mp4, m4p, m4v, mp3, mpa, aac, oga, aif, iff, m4a, wav, wma, 3g2, 3gp, asf, avi, flv, mov, swf, vob, wmv, mpeg, opus, and webm.
