The percent match values at the following tables will give you an overview which options are the best to detect duplicates between the different audio formats.
We have done several tests to determine the recognition rate for similar or almost identical audio files using different options.įor the tests we have converted a WAV file (1411 Kbits/s 16bit 44100kHz Stereo) into different audio formats.Īll new audio files have been converted with stereo sound unless explicitly described otherwise. This option enables you to compare only audio files with the same file extension. Here you can specify the comparison method to be used to generate the checksum.Ĭompare only files with the same file extension The percentage always refers to the reference audio file of a group which will be shown in a different text color. The calculated percentage matching between two audio files will be shown at the column Match. Here you can specify the minimum percentage matching of two audio files. The standard value for the scan length is 30 seconds. Here you can specify how many seconds at the beginning of the audio file should be used to calculate the checksum.Ī value between 15 and 999 seconds can be set for the scan length. (*) An error message will be shown at the log pane.
