Compare Audio Contents, 100% Accurate Result

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. 


Built-in High-speed Comparison Algorithm

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

Supports all Common Audio Types (About 500)

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. 

One-click to Get Result

Very Easy to Use, Only Need 1 Click to Get Result

Scanning Sources

Flexible Sources: Drives, Folders, Files and Types

You can specify the drives, folders and / or files to scan at the “Select resources” area on the left, specify the audio types (MP3, WMA, WAV, M4A, IFF, MOD and all other types) to be compared at the “Select type(s)” area on the right, can also specify excluded directories on the “Options” interface. 

Reusable ResultReusable Result: Save / Load the Duplicate Audio Listing

When there are many duplicate audio files, and you need to carefully review the results and then check and delete those that are not needed, it may be impossible to process all the results due to time reasons, such as shutting down PC after get off work or bedtime. At this time, it is very useful to save the repeated list so that it can be processed next time when your PC is turned on. Just click the “Save” button (disk icon) on the result interface to save result, and click the “Load” button (down arrow icon) on the main/result interface when you need.

Helpful OptionsHelpful Options: Smart Selection, Sub Folders, Excluding Paths, etc.

We provide a number of practical options to help you use this product better and faster, such as audio types manager, smart selection, play a sound after scanning, scan all sub folders for a specified path, do NOT scan the hidden files anyway, do NOT scan the listed system / special folders, etc.
