The Ultimate Duplicate Music Finder (2025)
After years of development and user feedback, one question remains: what makes a truly great duplicate music finder?
It’s not just about finding files with the same name. It’s about accuracy, speed, and format support. It’s about a tool that works silently in the background, learns your collection, and keeps it clean — automatically.
Audio Comparer was built from the ground up to be that tool.
1. Accuracy: Finds Duplicates by Sound, Not Names
Most tools fail because they rely on filenames, tags, or file size. But duplicates aren’t always obvious. You might have:
- The same song saved as “Track01.mp3” and “Artist - Song.flac”
- A low-bitrate version from a download and a high-quality rip from a CD
- A file with missing tags and another with full metadata
Audio Comparer doesn’t guess — it listens. Using advanced audio fingerprinting, it analyzes the actual sound of each file, so it can match duplicates regardless of format, name, or tags.
2. Speed: Scans Thousands of Songs in Minutes
Audio Comparer is optimized for performance. It takes just 1–2 seconds per song to analyze and remember the audio. Once scanned, your library is indexed — and future scans are even faster.
You can scan your entire collection, divide it into audio groups, or focus on specific folders. The comparison process is lightning-fast, with results appearing in seconds.
And yes — it works with iTunes, external drives, and network locations.
3. Format Support: Works with Everything
Your music collection probably includes a mix of formats. Audio Comparer supports them all:
MP3, FLAC, WMA, AAC, OGG, WAV, APE, WavPack, and more.
It doesn’t matter if your files are 128kbps or 24-bit/192kHz — if they sound the same, Audio Comparer will find them.
More Than Just a Duplicate Finder
Audio Comparer is designed to be your long-term music library guardian:
- Perfect memory: Once it knows a song, it remembers it forever. New files are compared against the entire database.
- Smart cleanup: It can suggest the best-quality version based on bitrate, format, and file integrity.
- iTunes integration: Removes duplicates from your iTunes library while preserving playlists and ratings.
- Built-in player: Preview any track before deletion.

What Our Users Say
Works across formats
"I was amazed that it could match a 128kbps MP3 with a 320kbps version and even a FLAC file of the same song. No other tool I’ve tried can do that. Audio Comparer is the first program that truly understands audio content, not just filenames."
