No. Zipping and unzipping an MP3 file will not affect the quality of the MP3. However, if you are trying to compress the MP3s, you will probably not save much disk space because, I believe, MP3s are already compressed.
Sound quality in an MP3 player is mostly related to the quality or bit rate at which the MP3 was made.In general the MP3 is not recommended by audiophiles because it loses sound quality.Therefore no MP3 gives you really good sound quality except when using the highest quality MP3 music files.
The primary advantage is that it makes your files smaller. Smaller files do not take up as much room on your storage device as larger files. The primary disadvantage is that you might loose sound quality or fidelity.
Lossless data compression preserves the full resolution of the sound, meaning that no sound quality is lost during the compression process. Sound files compressed with lossless software are an exact copy of their original.
AAC files are usually smaller with better sound quality than an MP3 file.
Why do MP3 files provide music of inferior quality than WAV files? Because MP3s are designed to save space and are compressed. Good luck. Alex 2022
Zune does not support .wav files. You need to convert them into .wma lossless files for Zune to be able to play them. Supposedly the reason for this is that .wma files are smaller, with no loss of sound quality.
How many hours of what? If you are referring to music or sound files, a typical value is 1 MB per minute, although this can vary a lot, depending on the sound quality.
Most mp3 files are stereo. That doesn't mean that there aren't mono mp3 files it's just that most music is stereo. MP3 is a standard method of compacting files with minimal loss of quality of the sound.

Sound quality can be improved by getting better speakers and purchasing a quality reciever.
Probably a combo of poor audio files + poor ipod sound + poor wires. I didn't like my Ipod on my stereo, realized how bad it just does sound!!
MP3 sound files have an .mp3 file extension, and common file extensions for raw, uncompressed sound files are .wav and .aif. Pg. 474
