Sorry if this has already been discussed. I’m using Audacity to add metadata to some tracks. I import the (WAV) file, add my metadata, and then export it. However, the new exported file reduces the size by almost 20 MB. I want the exported file to be the same size as the original. Any idea what’s going on? I’m using OS X 10.11.
From what size to what size? What percentage change?
Do you use some other application that can read metadata in WAV files?
Audacity is a poor choice of metadata editor because:
a) it is slow (the audio file has to be read from disk and then rewritten back to disk
b) unless you are using 32-bit float format, the exported file will probably not be a bit perfect copy of the original.
