isimSoftware Duplicate MP3 Finder

Just a faster duplicate music finder

with 100% accurate results you will love!

Compare whether audio files are the same at the binary level, that is, compare audio contents. Since only the audio contents are compared, the truly duplicate audio files must be found, regardless of whether the audio names and modification times are consistent. 

High-speed

This product uses our original "audio binary virtual crosspoint intelligent memory" algorithm to quickly obtain the hash value of all audio files in the scan source, and then uses the fast hash reverse sorting technology to obtain a list of duplicate audio files at one time. These repeatedly tested and optimized internal algorithms make our product to be much faster than most other similar software under the premise of ensuring the accuracy of the results.

CheckSmart Selection and Other Multiple Checking Methods

Except to quickly, comprehensively and accurately find duplicate audio files, another important function of our product is to quickly and accurately delete unwanted ones. To this end, we investigated and analyzed a large number of actual user behaviors and the reasons for repeated audio files, innovatively developed the powerful automation function - "smart selection". In addition to smart selection, our product also provides other 5 check methods, e.g. by paths, by drives, etc. 

Supports all Types

Except MP3, WMA, WAV, M4A, IFF, MOD, etc. these 13 common types, it supports about 500 other types. More importantly: even if you have a very special audio type that is not listed and needs to be found, you can also easily add it through the "Add..." button on "Audio types manager" interface.
