does it convert lossy file to lossy in its output?

Hi, I'm not sure if this is the right place to ask this question, but I would appreciate if anyone could answer my questions.

I'm using a apple downloader script above, it uses aria2c.exe, mp4box.exe and mp4decrypt.exe.

I compared the downloaded song from this script to an itunesmatch downloaded version both from the same link, however the audio stream did not match. So I was wondering that did it convert the song after decrypting it? I'm not exactly sure how it works.

The decryption process does not change the audio samples at all, it just decrypts the data. So you may not be comparing exactly the same things (if you don't have the original that was encrypted, it's hard to know what to compare against)

Thanks for your explanation! do you consider the purchased version of the song as the original that was decrypted?
