Audio file comparer
This utility allows you to compare two files and create a file that contains
the difference between the two, a “delta file”. This is useful for example to:
See the effect of using an equalizer by comparing the file before and after. The
delta file will show what was added.
Check the noise added by a processor, again by comparing.
Compare two digitally recorded files to check for dropouts.
Proceed as follows:
1. Make sure that the two documents you want to compare are open.
2. Select “Audio file comparer…” from the Analysis menu.
3. Fill out the dialog box and click OK.
Click the question mark icon in the dialog for details. Here’s a run down of the major possi-
bilities:
The program can create a delta file, that is, a file that only contains the differences
between the two files. This allows you to hear the difference between two files, for
example to check what got lost when you applied data compression to a file.
The program can add markers at positions where differences are found. For this
to make sense, the differences between the files must be small.
