I've always wanted to know whether there is any true quality loss in the
following circumstances:

1. I burn a 192 kbps mp3 file to CD as a .wav file so that it can play on
a CD player. If I re-create an mp3 file at 192 kbps from that same CD, is
there any quality loss?

2. I open a 192 kbps mp3 file in Soundforge to edit. Soundforge creates a
temporary file for editing. Once I edit the file, I save the new file as a
a 192 kbps mp3 file. Is there any quality loss in this process?


Yeah there is, but minimal and probably not noticeable, but if you
repeat that a dozen times then there'll be perceptible loss. Use a
bitrate of 256 or 320 if you wanna edit and re-save to MP3 all the
timem that way you'll only have real loss after the 100th time. Better
yet, use MP4, it's way better than MP3 and can handle the same
molesting you're doing to your song at half the bitrate.

3. I run a 192 kbps mp3 file through a normalizing program like Mptrim. If
the program makes changes to the file, such as eliminating silence at the
beginning of the file and normalizing the volume, is there any quality loss?

Not really. But obviously, if you set the volume too low and then
amplify back to normal then you will raise the noise level to what was
inaudible before. Apply common sense before doing anything to your
song.

4. When zipping and unzipping mp3 files in Winzip and WinRar, is there any
quality loss?

Thanks

Lol... you're full of ****. Winzip and WinRAR are both lossless,
meaning no quality loss.
