Loss of data?
« on: 17 Aug '02 - 19:39 »
I have a simple beginner question. If I convert my mod files into mo3 and back into their original form with unmo3, can I be sure that no data is lost in the samples? Isn't mp3 compression always lossy on some frequencies?

As a second question, why at all design mo3 for back-translation, doesn't that obfuscate the format quite a bit?

Sorry, this is a case of RTFM, I didn't see:

"A lossless sample codec is also incorporated, and the whole file structure is compressed too."

The sample quality is actually retained remarkably well when using a good encoder (eg. LAME or OGG), so that it can be impossible to tell the difference despite the MO3 being a fraction of the size :)

However, you should always keep an unpacked (or losslessly packed) version of your song as the "source", and use the packed version for redistribution.

Just in case that wasn't obvious. :)

(therefore, I see little point in the MO3 decoder... isn't it kinda like converting a .JPG to a .BMP?)

But if your favourite painting program does not support .JPG?...
